Known Traveler Number program: What is it, and should you get 1?

Editor's Note

When you travel, there are a few pieces of information you probably like to keep handy, including your frequent flyer number, your passport number and your trip confirmation number.

However, another number comes into play if you have TSA PreCheck or Global Entry : your Known Traveler Number. It's an important number that ensures access to the TSA PreCheck lanes .

Here's what to know about getting a KTN, how to find it and how to ensure it's attached to your flight reservations.

What is a Known Traveler Number?

A KTN is a nine-digit code each TSA PreCheck and Global Entry member receives from the U.S. Department of Homeland Security upon approval for one of those two programs. Members of a couple of other Trusted Traveler programs get a KTN as well.

The code may be a combination of both letters and numbers. It's your identification number that proves you're a member of one of these programs and shows that you are eligible to use the TSA PreCheck lanes at U.S. airports.

Travelers with a KTN have gone through an application and screening process , and they are known and recognized as travelers by the U.S. government.

Should you apply for a Known Traveler Number?

Getting a KTN is helpful for air travel because if you have one, it means you're a member of a program that gets you shorter wait times.

A KTN is your key to access the TSA PreCheck lanes. These lanes typically have shorter lines and allow members to undergo a less intrusive screening process than the standard lanes. About 99% of TSA PreCheck customers wait 10 minutes or less at security, according to the Transportation Security Administration.

There are several ways to get a KTN through different Trusted Traveler programs run by the DHS. Each program requires travelers to submit an application and go through an interview process. Those interviews generally occur in person at enrollment centers for first-time applicants, with many enrollment centers located at airports. The government is allowing virtual interviews for certain applicants, often those seeking to renew their membership.

Each program that provides travelers with a KTN has a fee, and memberships in all programs are valid for five years. Many credit cards also offer application fee credits for Global Entry or TSA PreCheck .

TSA PreCheck

If you've applied for TSA PreCheck, gone through the screening process and received confirmation of your approval into the program, you'll receive a KTN from the government.

TSA PreCheck offers a fast-tracked security experience for its members. When going through the TSA PreCheck lanes, you generally won't have to remove your shoes, take laptops or liquids out of your bag, or go through the full-body scanner.

The application fee is $78 for first-time applicants.

Global Entry

If you've received your TSA PreCheck membership by applying for Global Entry, you'll receive your KTN through your Global Entry membership.

Global Entry is a U.S. Customs and Border Protection program that allows travelers designated as low-risk by the U.S. government to use faster customs lines when returning to the U.S. from abroad. Members also get access to TSA PreCheck.

The fee for an application to this program is $100.

If you're planning to travel internationally and within the U.S. multiple times in the next five years, Global Entry is probably your best bet since it gets you expedited screening both at customs and at TSA checkpoints for only $22 more than a standard TSA PreCheck membership.

Nexus and SENTRI

The DHS has two other Trusted Traveler programs for travelers entering the U.S. from Canada and/or Mexico. Nexus and SENTRI also provide members with TSA PreCheck access and, thus, a KTN.

Nexus allows pre-screened travelers to use expedited processing when entering the U.S. from Canada by air or land. The fee for this program's application is $50.

SENTRI allows pre-screened travelers expedited entry into the U.S. from Canada and Mexico by air, land or sea. The application fee for this program is $122.25.

How do you add a Known Traveler Number to your travel bookings?

Once approved for TSA PreCheck, Global Entry, Nexus or SENTRI, you'll have to follow one additional step to ensure "TSA PreCheck" is printed on your boarding pass: You have to attach your number to your airline profile.

If you're just looking to attach your number to a single reservation, you can typically do this when filling out your personal information at checkout when booking a flight. However, we recommend always flying with a frequent flyer account to earn miles .

If you have a frequent flyer account, you can attach your KTN right to the personal information section of your airline profile. Once you do this, your KTN should be automatically added to each booking you make with that airline, as you include your frequent flyer number on the reservation. You typically can add your KTN to an existing reservation, too.

What to do if you forgot to add a KTN to your flight

If you already booked a flight and forgot to add your Known Traveler Number to your reservation, don't fret. You should be able to easily pull up your reservation and add your KTN.

Go to the airline's website or mobile app. Pull up your reservation using the confirmation number (or record locator) the airline gave you when you booked your trip. Then, go to the traveler information section. There should be a line that says "Known Traveler Number," "KTN" or "Secure Traveler Information." That's where you put your KTN.

If you've already checked in for your flight and downloaded your boarding pass, you may need to re-download the boarding pass to see "TSA PreCheck" appear.

Where can you find your Known Traveler Number?

The time when you'll most likely need your KTN handy is when booking a flight or updating your airline profile. This goes for new members of TSA PreCheck, Global Entry, SENTRI or Nexus, as well as existing members who might be flying with an airline for the first time since joining one of those programs.

With all the numbers, passwords and accounts we have to keep track of in our lives, it's easy to lose your KTN ... and most of us probably don't know our number by heart. Fortunately, there are a few ways to locate it.

If you're a standard TSA PreCheck member looking to track down your number, you can use this page from the DHS to put in your personal information and look up your number.

If you received your KTN through the Global Entry program, you have a couple of options. If you have your physical Global Entry card, check the backside. Your nine-digit "PASSID" is your KTN; it may start with "15," "98" or "99."

Another way to locate your Known Traveler Number is to log in to your Global Entry or other Trusted Traveler Program account. There, you should be able to see which program you're enrolled in, as well as your membership number/PASSID, which, again, is your KTN. You should also be able to see when your membership expires.

An additional option for tracking down your number is to check your frequent flyer account for an airline you've recently flown with. If your membership in one of the Trusted Traveler programs is active and you've used TSA PreCheck before, odds are your KTN is on file with one or more airlines you regularly fly.

For this option, you'll need to go to your airline profile. If your KTN is in your profile, you should see it listed under your personal information.

Bottom line

A Known Traveler Number is a code that gets you into the TSA PreCheck lane. It's how the airline and government recognize a trusted traveler who is a member of TSA PreCheck, Global Entry or other similar programs.

Keep your number handy and add it to your airline profile. If you're not a member, consider enrolling in one of these programs that gives you a KTN and makes your trip through the airport less of a hassle.

Known Traveler Number Guide: (How to Lookup, Global Entry, Pre-Check) [2023]

This comprehensive article will tell you everything you need to know about your Known Traveler Number.

I’ll cover how you can get one and the best way to do that with programs like TSA Pre-Check and Global Entry. I’ll show you how to look-up your Known Traveler Number and add it to your travel itineraries with airlines like United, Southwest, and Delta.

Finally, I’ll explain the differences between a Known Traveler Number and a Redress Number.

Table of Contents

What is a Known Traveler Number?

A Known Traveler Number, also called your “KTN,” is a 9-digit number used to link your TSA Pre-Check enrollment to your travel itinerary in order to ensure that you can receive TSA Pre-Check benefits like expedited security screening.

This is the same number used for other trusted traveler programs, such as Global Entry, NEXUS, and SENTRI . However, for these latter programs, this number is known as your “PASSID.”

Tip: Use the free app WalletFlo to help you travel the world for free by finding the best travel credit cards and promotions!

Why do you want a Known Traveler Number?

With a Known Traveler Number, you can participate in TSA Pre-Check, which means you’ll be able to breeze through security at airports.

How do you get a Known Traveler Number?

You can get a Known Traveler Number by signing up, getting approved, and paying the fees for any of the following programs:

TSA Pre-Check

Global entry.

As already discussed, TSA Pre-Check will usually get you through airport security in a breeze.

You’ll usually get access to a priority security line which is often much shorter than the standard security line (though not always, unfortunately).

You’ll also be able to go through a less restrictive and invasive screening process. You often only have to pass through a traditional metal detector (as opposed to the full-body scanners) and you also get to enjoy the following benefits:

• Shoes can stay on
• Belt can stay on
• Light jackets can stay on
• Laptops allowed to stay in bag
• Liquids ( 3-1-1 Rule ) can stay in bag

This program costs $78 to enroll for five years and it does not require the extensive interview process that Global Entry requires. There are multiple ways to get TSA Pre-Check for free and you can read about those here.

Global Entry would be my preferred method for obtaining a Known Traveler Number. That’s because not only will you get TSA Pre-Check, but you’ll also get expedited entry at Customs and Immigration when making your way back into the US.

This program does require you to attend an interview to be approved but the interview process is not difficult at all . If you’ve got a clean criminal history and come prepared with your documents then you should pass the background check and interview without any issues at all.

In some cases this “interview” process will only take about five minutes total.

You might get asked some very basic questions like what countries you have visited and whether or not you have traveled for business or pleasure. It’s hardly anything close to an interrogation in most cases.

The hardest part is often scheduling the interview because availability can be limited and in some cases it might take weeks (or even months) to find an open slot.

Luckily, some airports offer interviews upon arriving from international locations. So if you have some international travel coming up, this can be one of the easiest ways to get approved for Global Entry.

There are many credit cards that come with a $100 statement credit for your Global Entry application fee, so it’s very easy to get this program for free. My personal recommendations for getting a $100 statement credit for your Global Entry/TSA Pre-Check is to go with the United Explorer Card. It has great perks and a low annual fee and you can read more about it here! 

Since you’ll get both TSA Pre-Check and expedited entry back into the US, I think Global Entry is the way to go for many people.

NEXUS is a joint program between the US and Canada that will grant pre-approved, low-risk travelers expedited entry into  both  Canada and the US. Specifically, membership in the NEXUS program allows you to reduce your wait times at designated ports of entry by:

• Using dedicated processing lanes at land border crossings
• Using NEXUS kiosks when entering Canada
• Using their card in dedicated SENTRI lanes along the U.S.-Mexico border
• Using Global Entry kioks when entering the United States, and
• Calling a marine telephone reporting center to report your arrival into the United States and Canada

You may also be granted access to the Canadian Air Transport Security Authority (CATSA) Security Line at some Canadian airports to expedite airport pre-boarding security screening. (This is like a Canadian version of TSA Pre-Check.)

Just like Global Entry, NEXUS will require you to clear a background check. The difference is that this background check also is submitted to Canadian authorities, such as the  Canadian Security Intelligence Service (CSIS), Royal Canadian Mounted Police (RCMP).

One of the major draws to the NEXUS program is that the  application fee is only $50 . This is surprising since NEXUS comes with both Global Entry and TSA Pre-Check, which cost $100 and $85 respectively. For people who live near or travel between the US/Canada border, NEXUS is an especially attractive bargain.

The Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States.

You can enter the United States by using dedicated primary lanes into the United States at Southern land border ports so this is a program you might be interested in if you’re traveling between the US and Mexico a lot.

You might be a little overwhelmed with all of the different Trusted Traveler programs and perhaps you’re not sure which program you should sign-up for.

If that’s the case you can check out this TSA tool  which can help you narrow down what program is most ideal for you based on your citizenship, number of flights, and travel destinations.

Other related travel programs

CLEAR is a privately owned service offered to passengers that allows them to bypass the lines going into airport security, whether you are going into the standard security line or the TSA Pre-Check line.

In order to use it you find the CLEAR line leading to security which should have little to no line and then you simply scan your boarding pass and biometric data and then you’re off to the races and able to skip whatever line you would have been waiting on. You don’t even have to show your ID.

CLEAR can be great for frequent flyers in busy airports but it’s not cheap at $179 per year (though cheaper promos are often available). This program does not require you to have a Known Traveler Number.

Mobile Passport

Launched in the fall of 2014, Mobile Passport Control is an app, developed by Airside Mobile and Airports Council International-North America in partnerships with CBP, that you can download to use in order to expedite your entry into the US. It’s available in the  Apple App Store  and  Google Play .

It’s free to use and can be just about as good as Global Entry at some airports, though I’d still take Global Entry over Mobile Passport.

That’s because Global Entry gets you Pre-Check and also allows you to get through customs AND immigration while Mobile Passport often only get your priority access through immigration. This program also does not require you to have a Known Traveler Number.

Adding a Known Traveler Number

Once you have your Known Traveler Number, you’re going to need to add that number to your travel profiles for the various airlines so that your Known Traveler Number will automatically show up in your itineraries.

However, you should note that your Known Traveler Number will NOT automatically show up in all of your travel  itineraries.

Many people assume that once they add their Known Traveler Number to their profile, it will always show up but that’s not the case. So you always need to double check that your KTN was added.

Below, you can see how to add your Known Traveler Number to some of the major airlines. For whatever reason, it is not always the easiest thing to do since you often have to click around a lot.

Usually you can find where to input it if you just look for your profile and a button allowing you to edit your profile, but the steps below should help you locate this.

American Airlines

Sign in to your American Airlines account and then click on your name at the top of the page. Then click on “your account.” Next, click on “edit account” and then click on “Information and password.” Scroll down and then under “Secure traveler,” you will see where to input your Known Traveler Number.

Sign in and click on “My Account” and then scroll to “My Preferences” to change your personal details within your profile information.

Sign in and click on Profile and Preferences and then click on “Travel identification documents” and then you’ll see the area to enter it in below.

Go to the Delta website and log-in and then proceed to My Delta -> My Profile -> Basic Info. You’ll then see a field where you can input your Known Traveler Number.

First, sign in to your JetBlue account. Click on the arrow in the upper right corner by your name and then click on “Edit profile.” Scroll down and you will see where to input your information.

Hawaiian Airlines

First, sign in to your Hawaiian Airlines account. Go to My Account and under that click on “Profile & Settings.” Click on the travel tab and you will see where to input your information.

Travel portals and OTAs

Most online travel agencies (like Expedia) will allow you to enter in your Known Traveler Number into your profile which should populate into your itinerary when you make a booking.

But since you’re dealing with a third party, you should always verify that your number was properly included in your booking.

Add Known Traveler Number after booking?

If you add your Known Traveler Number to your profile after you make a flight reservation, there’s a good chance that your flight itinerary is not linked to your Known Traveler Number and you won’t get TSA Pre-Check. 

In that case, you should be able to call up the airline and request for them to input your number into your itinerary.

You could also just wait until you arrive at the check-in desk for baggage and request for your Known Traveler Number to be added to your boarding pass.

Also, sometimes you’ll have to re-add your Known Traveler Number to specific itineraries. It’s not always clear why this happens but sometimes you’ll just have to do it.

If you ever are given a boarding pass without TSA Pre-Check on it and you know you have a TSA Pre-Check membership, simply approach an agent at the check-in desk and tell them you would like to add your Known Traveler Number.

It’s usually no problem for them to do this and they can re-issue you a boarding pass in a couple of seconds that has TSA Pre-Check.

For the reasons above, I highly recommend that you keep your Known Traveler Number somewhere easily retrievable like in your smart phone in a folder or app that you won’t forget about and can quickly pull up.

Where can I look up and find my Known Traveler Number?

If you are a member of the TSA Pre-Check Application Program you can, look up your KTN online .

If you are a member of another trusted traveler program, such as Global Entry, NEXUS, or SENTRI,  log on to the Trusted Traveler Program website  to obtain your PASSID, which once again is the same as your KTN.

You’ll find it right under “Program Memberships.”

You can also check the back of your trusted traveler cards for your PASSID. Note that TSA does not issue an ID card like Global Entry, NEXUS, and SENTRI do.

Related: Can You Get Through TSA and Fly with No ID?

What is a redress number?

You might also be wondering about a redress number since that field often shows up near where you input your Known Traveler Number.

A redress number is the record identifier for people who apply for redress through the DHS Travel Redress Inquiry Program (DHS TRIP) .

“DHS TRIP is for travelers who have been repeatedly identified for additional screening and who want to file an inquiry to have erroneous information corrected in DHS systems.”

For example, someone might share the same name as another person on a no-fly list and that might bring up a red flag every single time this unfortunate traveler attempts to board a plane.

The redress number will help those people avoid additional searches, pat downs, and questioning in the future.

So in case you were wondering a redress number really has nothing to do with your Known Traveler Number.

Known Traveler Number for Military members

If you are a member of the military, you can utilize TSA Pre-Check for free.

Members of the U.S. Armed Forces can get expedited screening including those serving in the U.S. Coast Guard, Reserves, and National Guard.

This can be done by using the official Department of Defense (DoD) identification number when making flight reservations. Your 10-digit DoD ID number is located on the back of your Combined Access Card ID and it is not the same as your SSN. Read more about how to utilize this benefit here.

TSA Pre-Check vs Global Entry

Now that you’re aware of all of the benefits you might be wondering whether or not you should choose TSA Pre-Check or Global Entry.

The answer to this question depends a lot on your personal preferences.

If you are only going to be traveling within the US then your need for Global Entry will be nearly zero.

In that case, getting TSA Pre-Check should be just fine. The only drawback to that is that if an unexpected trip comes up you’ll lose out on the benefit you could have had with Global Entry.

On the other hand, if you’re going to be traveling internationally then you might want to think about Global Entry since it will save you a lot of time getting back into the country.

The two drawbacks to Global Entry are that it requires you to attend an interview and that the background check can be tough to clear if you have anything on your record like a DWI, DUI, etc.

Known Traveler Number FAQ

The easiest way would be to get approved for TSA Pre-Check .

No, you do not need a Known Traveler Number for CLEAR?

At the time of booking, you will typically see a field where you can enter your Known Traveler Number. In addition, you can add your Known Traveler Number to your frequent flyer profile. If you are at the airport, you can also ask an agent to add your Known Traveler Number to your boarding pass.

There is no practical difference and these are essentially the same.

As you can see, getting a Known Traveler Number can be very easy and can even be done for free with the right credit card.

I recommend going with a program like Global Entry to get your PASSID/Known Traveler Number and using a credit card with a $100 credit for Global Entry.

If you always keep your Known Traveler Number with you at all times you’ll be able to add it to your boarding pass when needed and there shouldn’t be any major issues.

I only travel to the States. Which one should I apply. I read and I see so many type to apply. Quite confusing. Truly appreciate if you can advise . Thank you Regards Teresa

If you don’t travel outside the US, TSA Pre-Check is a solid option.

How to Find Your KTN (Plus How to Enroll in or Renew PreCheck)

Last Updated: February 18, 2024 Fact Checked

Finding Your KTN

Enrolling in a trusted traveler program, renewing your tsa precheck authorization, expert q&a.

TSA PreCheck makes it easy for you to breeze through airport security without having to take off your shoes, belt, or jacket. But to access those PreCheck lanes, you need to enroll in the service and provide your PreCheck number—called a Known Traveler Number (KTN)—to the airline when you book your flight. If you've forgotten your KTN, the easiest way to find it is to check the TSA Enrollment website.

Things You Should Know

• Look for your KTN on official sources, such as your approval letter, or the TSA Enrollment website , if you're a US citizen.
• Use the PASSID on your membership card as your KTN if you're enrolled in the Global Entry, NEXUS, or SENTRI programs.
• Enroll in Precheck programs online to get a KTN. Schedule an in-person appointment, supply the required documents, and pay the application fee for approval.
• Check your TSA Precheck status and fill out the renewal application online within 6 months before it expires so it's continuously active.

• Your PASSID is a 9-digit number that usually starts with 15, 98, or 99.
• If you previously enrolled in TSA PreCheck directly, but then enrolled in Global Entry, NEXUS, or SENTRI later, use the PASSID associated with the later program as your KTN—it supersedes your previous enrollment.

• This receipt isn't the same as your approval letter. Your approval letter was mailed to you after your Enrollment Center appointment and has your KTN on it. Your UE ID and your KTN are two different things.

• The TSA also has an online form , but you'll probably get a quicker resolution by calling.

• TSA PreCheck : access to PreCheck lanes for airport departures; US citizens and lawful permanent residents are eligible; $78 for 5 years
• Global Entry : entry to the US from international destinations by air, land, or sea; access to PreCheck lanes for airport departures; US citizens, lawful permanent residents, and select foreign nationals are eligible; $100 for 5 years
• NEXUS : entry to the US from Canada by air, land, or sea; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents as well as Canadian citizens; US citizens and permanent residents, Canadian citizens and permanent residents, and Mexican nationals are eligible; $50 for 5 years
• SENTRI : entry to the US from Canada and Mexico by air or land; includes access to PreCheck lanes for airport departures for US citizens and lawful permanent residents; US citizens and permanent residents, as well as all foreign nationals, are eligible; $122.25 for 5 years

• If you'd rather apply in person, enter your ZIP code in the TSA Enrollment Center locator to find the nearest Enrollment Center.

• If you need to reschedule your appointment, you can do that from the TSA Enrollment website as well. The Enrollment Centers do take walk-ins, although you may have to wait a while, especially during peak hours.

• List A : unexpired passport book or card, permanent resident card, unexpired US enhanced driver's license or enhanced state-issued ID
• List B : unexpired driver's license or state ID, unexpired US military ID, expired passport within 12 months of expiration, US birth certificate, US certificate of naturalization

• Many credit cards help offset or even cover the cost of TSA PreCheck membership as a benefit to customers—especially cards with travel or airline miles incentives. Contact your credit card company to see if this is a perk for you.

• The representative who fingerprints you will give you your receipt, which includes your Universal Enrollment ID (UE ID). Hang on to this! You'll need it to look up your KTN online.

TSA PreCheck®

What is tsa precheck ® .

The TSA PreCheck ® program expedites traveler screening through participating TSA security checkpoints (for a complete list of participating airports, visit the TSA PreCheck® Airports and Airlines page 1-866-289-9673 -->). No need to remove shoes, belts, 3-1-1 liquids, laptops, or light jackets.

Are You Eligible?

U.S. citizens, U.S. lawful permanent residents and citizens of partner countries enrolled in Global Entry , NEXUS or SENTRI are eligible to participate in TSA PreCheck ® , as well as Canadian citizens who are members of NEXUS.

How It Works

If you are an eligible Global Entry, NEXUS or SENTRI member, enter your membership number (PASS ID) in the “Known Traveler Number” field when booking reservations, or enter it into your frequent flyer profile with the airline. The membership number enables Transportation Security Administration’s (TSA) Secure Flight System to verify that you are a legitimate CBP Trusted Traveler and eligible to participate in TSA PreCheck ® .

Where You Can Find Your Membership Number

You can find your Trusted Traveler member number by logging into your Trusted Traveler Programs (TTP) account. Your membership number is listed toward the bottom of the page. Your membership number is also located on the back of your Trusted Traveler card in the upper-left corner.

The TSA PreCheck ® program expedites traveler screening through TSA security checkpoints. For a complete list of participating airports in TSA PreCheck ® or for more information, visit www.tsa.gov or call the TSA Contact Center at 1-866-289-9673 .

If you’re new to TSA PreCheck or Global Entry, you may be wondering what a Known Traveler Number (KTN) is, how it works, and why there’s a KTN box when booking flights, but there isn’t one for your TSA PreCheck or Global Entry number. Here’s what you should know about your KTN.

What Is a Known Traveler Number?

Your Known Traveler Number is your membership number with a Trusted Traveler Program. This number is what allows you to access TSA PreCheck security lanes and Global Entry lanes (depending on which Trusted Traveler Program you join).

How To Get a Known Traveler Number

To acquire a Known Traveler Number, you must participate in one of the Trusted Traveler Programs. These are:

• Global Entry
• TSA PreCheck

Global Entry and TSA PreCheck are by far the most popular options in the U.S. The NEXUS and SENTRI programs also provide a Known Traveler Number, though these programs are much less commonly used in the U.S.

Credit Cards That Reimburse for Global Entry, TSA PreCheck, and/or NEXUS Application Fees

Many premium credit cards will reimburse you for the application fee for either Global Entry or TSA PreCheck (including American Express, Capital One, Chase, and Citi, which all provide cards that offer an application fee reimbursement).

Since several cards offer this benefit, consider the other benefits of your credit card options before you choose one. Look at the points they earn, trip delay protection, purchase protection, elite status, or airport lounge access.

If your priority is earning tons of valuable (and transferable!) points, you might choose the Chase Sapphire Reserve card . It earns 5x points on air travel and 10x points on hotels and car rentals when you purchase travel through Chase Travel, 10x points on Lyft (through March 2025), 3x points on all other travel, and it comes with a Priority Pass Select membership for lounge access. You’ll also receive a $300 travel credit that is automatically applied to your first $300 in travel purchases each cardmember year (this includes taxis, Uber , Lyft , train tickets, flights, hotels, and more).

If airport lounge access and elite status are your top priorities, the Amex Platinum card and Amex Business Platinum card provide world-class lounge access , including Centurion Lounges and Delta Sky Clubs (when flying Delta), on top of a Priority Pass Select membership upon enrollment. Cardholders also receive elite status with both Hilton Honors and Marriott Bonvoy upon enrollment. To top it off, you’ll earn 5x Membership Rewards points when booking flights directly with an airline.

And for travelers who value simplicity in earning and redeeming their rewards along with a reasonable annual fee, consider the Capital One Venture X card . It earns 2x Capital One miles on all purchases and comes with the lowest annual fee among the most popular premium credit cards.

Whichever card you choose, all you have to do is use it to pay for the Global Entry or TSA PreCheck application fee, and you’ll automatically be reimbursed.

How To Find Your Known Traveler Number

Hot Tip: You can find your PASSID  (also known as your Known Traveler Number) on the back of your Global Entry, NEXUS, or SENTRI card.

If you only have TSA PreCheck, log in to the Trusted Traveler Program website to access your PASSID/Known Traveler Number. If you lose your Global Entry, NEXUS, or SENTRI card, you can use the Trusted Traveler Program site to find the number.

How To Add Your Known Traveler Number to Bookings

While it might not be apparent at first, you’ll be happy to know that your TSA PreCheck or Global Entry number is, in fact, your Known Traveler Number. Simply enter your Known Traveler Number in the appropriate field when booking your flight. This can also be done later — even at the check-in desk at the airport.

The vast majority of the time, you do not need to carry your Global Entry card to access the airport’s TSA PreCheck or Global Entry lanes. That said, there have been some recent reports of travelers being asked to show their physical card. This appears to happen most at airports that allow travelers with Global Entry to preclear security, especially for flights departing from Canada. It also may happen when entering the U.S. by car via NEXUS or SENTRI lanes.

Hot Tip:  Unlike when returning from most countries, if you want to access Global Entry lanes when returning from Canada, you will need your physical Global Entry card with you.

Global Entry or TSA PreCheck: Which One Is Right for You?

As anyone who’s been through airport security knows, it can be a frustrating hassle. To expedite the screening process  at many U.S. airports, TSA PreCheck access provides a much better experience. If you are returning to the U.S. from an international destination, Global Entry can make getting through customs a breeze.

If you mainly travel within the U.S., you might think that you only need to get TSA PreCheck — this is understandable, considering the fee is $78 compared to $100 for Global Entry.

However, a Global Entry membership also provides access to TSA PreCheck. When you account for the application fee reimbursement offered by several credit cards, why wouldn’t you go ahead and get Global Entry? With the right card, the impact on your wallet is the same — neither should cost you a dime!

By getting Global Entry, you can enjoy a quicker security experience when boarding flights in the U.S. If you decide to travel abroad, you can take comfort in the fact that returning to the U.S. will be easy.

Hot Tip:  If you have additional questions, don’t miss our piece on the top Global Entry FAQs and TSA PreCheck FAQs . 

Final Thoughts

Airports are becoming busier by the year, so having access to TSA PreCheck and Global Entry is vital for quicker and smoother security screenings. With so many credit cards offering to reimburse you for the application fee, there is no excuse not to have a Known Traveler Number.

Whether you get TSA PreCheck or Global Entry, you’ll be all set for a better airport experience — just enter your PASSID/Known Traveler Number when booking your flight.

Frequently Asked Questions

How do i know if i have a known traveler number.

If you have applied for and been approved for Global Entry, NEXUS, SENTRI, or TSA PreCheck, you have a Known Traveler Number. It is your membership number from one of these Trusted Traveler Programs.

Can you add a Known Traveler Number after booking your flight?

Yes. If you forget to add your Known Traveler Number at the time of booking, you can add it later. This can be done online or at the check-in desk at the airport. We recommend doing it online before checking in.

Why isn't my Known Traveler Number working?

If your Known Traveler Number isn’t working, the likely causes are:

• You, a travel agent, or reservations agent entered the number incorrectly
• Your name doesn’t match what is on your Trusted Traveler Program profile

Where do I find my Known Traveler Number on my Global Entry card?

Your Known Traveler Number can be found on the back of your Global Entry card. It is your PASSID number.

If you have NEXUS or SENTRI, your PASSID number will also be found on the back of your card.

How long is a Known Traveler Number good for?

Your membership with a Trusted Traveler Program lasts 5 years. At that point, you will need to renew your membership and pay another fee. Don’t forget to use a credit card that will reimburse you for the fee!

Redress Number vs. Known Traveler Number: What’s the Difference?

Many or all of the products featured here are from our partners who compensate us. This influences which products we write about and where and how the product appears on a page. However, this does not influence our evaluations. Our opinions are our own. Here is a list of our partners and here's how we make money .

Every time you book a flight, two little boxes loom large on the passenger information page: redress number and Known Traveler Number (KTN).

Even if you travel often, you may not know the difference. Here's how these two numbers differ, where to find them and how to know if you need either.

The main differences between redress and KTN numbers

Not every traveler will have a redress number or a KTN. In fact, the majority of travelers won’t have either. And if you do, you’ll know, because you will have gone through a lengthy application and approval process.

A redress number is exclusively for travelers who have experienced (sometimes often or repeated) difficulty or delays during security screening, whether traveling domestically or internationally, and who have started a redress inquiry with the Department of Homeland Security to resolve a misidentification issue.

A KTN, on the other hand, is granted to travelers who have applied and paid for Global Entry or TSA PreCheck in order to enjoy expedited security screenings at airports in the U.S.

What is a redress number?

A redress control number, more frequently known as a redress number , is an identifier given to individuals who were falsely identified as posing a threat to transportation security or public safety when flying. If you believe you have been incorrectly added to a watchlist or run into frequent screening problems and delays at border control — often as a result of having the same name as someone on the Transportation Security Administration's (TSA) watchlist — you might open a redress case to get your name cleared.

When you start a case with the Department of Homeland Security Traveler Redress Inquiry Program (DHS TRIP), you receive a seven-digit redress number, which essentially links you with your redress case.

Most travelers don’t have, nor will ever need, a redress number.

What is a Known Traveler Number?

If you’ve applied and been approved for TSA PreCheck or Global Entry, an expedited security screening program at airports across the U.S., you’ll receive a Known Traveler Number.

The nine-digit number is linked to your Trusted Traveler account and must be shared with airlines when booking in order to gain access to the dedicated TSA PreCheck line at security. You’ll know if you entered it correctly if there’s a TSA PreCheck logo, complete with green check mark, on your boarding pass.

Your Known Traveler Number can be found by logging into the Trusted Traveler Programs website. It’s also printed on the back of your Trusted Traveler card.

Do you need a redress number or Known Traveler Number?

If you’re traveling soon or in the midst of booking a flight and are wondering if you need either number, the answer is likely “no.”

KTNs are entirely optional, though are often worth the expense for frequent travelers. Plus, there's a way to get a KTN for free as part of the benefits of your travel credit card. Some credit cards offer statement credits that will reimburse you for TSA PreCheck or Global Entry application fees.

If you don’t have a KTN, don’t sweat it; you can leave that box empty.

Likewise, if you’ve never experienced delays or difficulties other than the occasional pat-down or random selection for bag screening at security or ports of entry, you probably don’t need a redress number, either, and can also leave that field empty.

» Learn more: What Chase cards come with TSA PreCheck?

Where do I enter a redress number or Known Traveler Number?

If you do happen to have either number, you can add them during booking on airline websites. After you’ve selected your preferred flights, when you come to a page that prompts you to enter the details of each traveler, you’ll find boxes for both a redress number and Known Traveler Number.

Enter either if you have them (or neither if you don’t) and they'll be linked to your booking.

You can also add either number to your frequent flyer account so they’ll be automatically entered during every booking and you don’t have to go searching for your number each time you travel.

The process for each program may look a bit different, but log into your profile, find the page where you can update personal information and enter your number in the corresponding text box. It will be saved for future bookings.

The bottom line

Whether you have a redress number or KTN depends entirely on you as an individual traveler. While a KTN is entirely optional and offers a way to move more quickly and easily through security, a redress number is reserved for those who regularly experience unnecessary delays or difficulties at checkpoints, often due to mistaken identity.

If you do have either, just make sure to include your number on your travel booking to help ensure a seamless and hassle-free trip through security.

Redress number vs. known traveler number: understanding the difference.

In the world of customs and border protection, you may find some of the terminology unclear. For example, you may have heard of redress numbers vs. Known Traveler Numbers (KTN) in the context of airport security. But what do those terms mean and what are the differences?

What is a redress number?

Much like other travel identification numbers assigned by the government, a redress number is designed to expedite the border security process.

Redress numbers are issued by the Department of Homeland Security to individuals who have previously experienced difficulties during screening at transportation hubs such as airports. These difficulties may include watch list issues, screening problems at ports of entry and situations where a traveler believes they have been unfairly or incorrectly delayed, identified for additional screening or denied boarding.

If you do think you're eligible for a redress number, you can apply online through the Department of Homeland Security's website. After submitting your application, it will become subject to approval, which can take up to 50 business days.

Upon approval, you will receive your redress number, which you'll be able to use when traveling. This should help you avoid difficulties at security screenings going forward.

Note that if your security issues relate to a criminal record or an instance of excessive intoxication, you will likely not be eligible for a redress number.

What is a Known Traveler Number?

Separate from a redress number, a Known Traveler Number is issued to people who apply to and are approved for TSA PreCheck ® , the program that allows approved travelers to access expedited security lines for domestic travel in the United States.

Additionally, while the terminology is slightly different, a similar identification number is issued to those who apply to and are approved for Global Entry, NEXUS and SENTRI, programs that allow for expedited access into the United States via air, land or sea. In this case, you'll be issued a PASSID number, which is entered in the same place as the Known Traveler Number when booking air travel.

Like a redress number, a Known Traveler Number is also issued by the Department of Homeland Security, and recipients must go through an application and screening process to be approved. This then grants entry to the TSA PreCheck line, which allows travelers to go through airport security without removing liquids, laptops, shoes, belts or light outerwear.

Redress number vs. KTN: Differences and benefits

The main differences between a redress number and a Known Traveler Number are the circumstances in which it's issued and used.

A redress number relieves part of the stress of traveling by making it less likely you will be targeted for additional screening, or delayed or denied boarding or entry. Ultimately, the goal of a redress number is to create a smoother traveling experience for those who have had difficulties with security in the past. It works to correct the potential misidentification of travelers as high risk, thus complicating their experience through security.

By contrast, a Known Traveler Number allows travelers to access specially approved security lines and screening processes designed to expedite their wait time. Additionally, unless you are an active member of the military, you pay for this perk. TSA PreCheck costs $78 as of April 2023 for a five-year membership. This fee is subject to change, so be sure to check the TSA PreCheck website for the most up-to-date cost. A redress number, on the other hand, is free.

If comparing a redress number vs. a Known Traveler Number, you'll find the “why" behind the two numbers the biggest difference. Redress numbers are intended to correct misidentifications that may lead to security issues for certain travelers, while a Known Traveler Number is a travel perk you can pay for. Ultimately, their goal is the same — to help make your travel a little bit smoother.

Known Traveler Number on Global Entry Card (Unlimited Guides)

If you are a frequent traveler who often enters or exits the US, you’re likely to be interested in any schemes that allow you to skip the security line to gain expedited access to the US territory – and several such schemes exist.

One of these is the highly popular Global Entry scheme, which allows those who have been accepted to pass through security a whole lot quicker than non-members. But what exactly is it?

To answer this and other similar questions, in this post, we have all the info you need to know about Global Entry and the all-important Known Traveler Number on the Global Entry card.

What is Global Entry?

Global Entry is a system that entitles members to expedited entry into the US at participating airports and some seaports.

Applicants for the scheme are assessed, and those deemed low risk may be accepted. Members of the scheme then gain access to expedited security clearance via automated control lanes on arrival in the US.

Who is eligible?

US nationals and US lawful permanent residents are eligible to apply for the scheme, as are nationals of the following countries:

• Dominican Republic
• Netherlands
• South Korea
• Switzerland
• UK (British citizens only)

In addition, Israel, Japan, Qatar, Saudi Arabia, Australia and Costa Rica are also in the process of joining the scheme.

However, applications to the scheme may be refused. Reasons for this include criminal convictions, providing false information on the application and customs-related offences, among others.

How do you apply?

Applications to the scheme are filed with US Customs and Border Protection. Following this, applicants are called to an in-person interview. Prior to the interview, all applicants undergo a rigorous background check to assess their eligibility for the scheme.

The fee for joining the scheme is currently $100 – and this is non-refundable in the case of an application being rejected.

Further details of the application process are available on the CBP website .

How do you know if you’ve been accepted?

After completing the interview, you may be notified of your acceptance into the scheme very quickly, sometimes almost immediately or within around 15 minutes – or sometimes within a couple of hours.

Once you are accepted, you will receive an email – and you will subsequently also receive notification by post, which will also contain your membership card if you have requested one.

What is your Known Traveler Number (KTN)?

So what is the all-important Known Traveler Number (KTN) – and where can you find it?

Your KTN is a nine-digit number that you need to communicate to airlines when booking flights and that will then grant you access to expedited security clearance.

This number will be communicated to you in the email you receive when you are accepted into the scheme, and it can also be found on the back of your membership card under PASSID.

You will also be able to find your number on TSA or Trusted Traveler Program websites, and airlines usually save the number when you use it with them for the first time, so you won’t need to find it again the next time you book with the same airline.

Once you have your number, you don’t need to carry or use the physical membership card for air travel – and the membership card isn’t usually issued unless you specifically request it.

What’s the procedure for using Global Entry?

When booking a flight, you should notify the airline of your KTN when you fill in the rest of your details.

However, if you don’t do this when booking your flight, you can notify the airline of your number later, sometimes right up until the day of your flight.

On arrival at a participating airport, Global Entry members proceed to designated Global Entry kiosks. These kiosks then scan the traveler’s machine-readable passport, and the traveler is required to fill out an online customs declaration form.

After this, the machine will produce a receipt that tells the traveler to proceed to baggage reclaim – which means the security check has been completed – or they will be told to proceed to an inspection booth to go through the regular entry procedures.

This means that once you have provided your KTN to the airline, the Global Entry kiosk will already have your number, so you won’t need to remember it or enter it again.

Note that Global Entry is only available at selected airports, and not all international airports in the US are part of the scheme.

How about for land and sea borders?

When entering the US via land and sea borders, Global Entry can also help expedite your passage through security clearance – but the procedure might be slightly different.

In this case, the Global Entry membership card is used at special “Ready Lanes” to skip regular security checks.

When entering from Canada or Mexico via land or sea, the membership card alone is sufficient, and you don’t need to carry a passport.

However, note that a valid passport is required to enter Canada, and the Global Entry card will not allow you to cross the border in that direction.

Where can you find your Known Traveler Number?

Once you have been accepted to the Global Entry scheme, you will be notified by email, and your nine-digit KTN number will be communicated to you in the email. You can then begin using it immediately.

If you have requested a membership card, this will later be mailed to you, and the number will be written on the back.

You will also be able to find your number on TSA or Trusted Traveler Program websites.

Can you use a Global Entry card instead of a passport?

No. Your Global Entry card doesn’t replace your passport, so you should always carry your passport when you travel internationally.

The exception to this is that the membership card may be used as a valid form of ID when entering the US via land or sea (but not air) from Canada or Mexico.

Do you need to carry the membership card with you?

No. You don’t need to carry the physical membership card, you just need to know your nine-digit KTN and communicate it to the airline before traveling.

Are membership cards issued automatically?

No. Membership cards are only issued upon request since the KTN is all you need to take advantage of the benefits of Global Entry when flying into participating airports in the US.

What are the advantages of requesting a Global Entry membership card?

Although you don’t need a membership card to enjoy the benefits of Global Entry when flying, you will need the card to use the scheme when entering the US overland or by sea from Mexico or Canada.

You can also use the card as a valid form of photo ID in certain places, so for many people, it’s still worth having – especially since it doesn’t cost anything extra to ask for it.

Does Global Entry guarantee expedited entry?

No. Sometimes even members of the Global Entry scheme are selected for standard or enhanced screening and will have to go through the necessary procedures instead of enjoying expedited entry into the US.

Can you add the number after reserving a flight?

Yes. Even if you don’t add your KTN during the booking process, you can still contact the airline before flying, sometimes even on the same day as your flight, to add the number to your reservation.

How long is Global Entry valid?

Global Entry is valid until five years after your next birthday on being accepted into the program. This means, for example, if you are accepted in January 2024 and your birthday is May 1 st , your membership will be valid until May 1 st , 2029.

How do you reapply?

The reapplication is the same as the initial application procedure, and the fee is also the same. However, not all those reapplying are required to go for an in-person interview – although in some cases, this can be necessary.

When can you reapply?

It is recommended that you reapply early since if your application hasn’t been accepted by the time your membership runs out, you may find yourself traveling while ineligible to enjoy the benefits of Global Entry.

It’s best to reapply at least six months before the expiry of your previous membership – but you can apply up to one year before, which effectively means on your birthday the year before your membership is due to expire.

How much is the fee for signing up for Global Entry?

The application fee is currently $100, and this is non-refundable, even in the case of a rejected application. The fee for reapplication is the same.

A valuable scheme for those who enter and exit the US frequently

As we’ve seen, Global Entry offers some valuable benefits to members of the scheme, and if you travel into and out of the US frequently, the $100 fee for a five-year membership will probably seem like money well spent.

Applying for the scheme is easy, and once you’ve been accepted, you can begin enjoying the benefits immediately, making use of expedited security clearance instead of wasting lots of time standing in line with everyone else.

To apply for Global Entry, you first need to create a TTP account. Then you can apply online, pay the application fee and schedule an interview at a Global Entry Enrollment Center. You’ll receive a PASS ID, which serves as the KTN, if you’re approved.

To offset the cost of TSA PreCheck® or Global Entry, certain travel credit cards reimburse cardholders for the application fee on their credit card statement .

• Global Entry, NEXUS or SENTRI: The KTN is the PASS ID. It’s nine digits long and begins with either 10, 13, 14, 15, 16, 50, 70, 80, 95, 98 or 99.

What if I can’t locate my Known Traveler Number?

TSA PreCheck ® members can look up their KTN online . Global Entry, NEXUS or SENTRI members can sign in to the Trusted Traveler Program website to retrieve their PASS ID number, which serves as their KTN.

How to use a Known Traveler Number

Adding a Known Traveler Number to an existing reservation

If you’ve already made an airline reservation, you can still add your KTN by contacting the airline by phone or online. Be sure your reservation’s personal information, like your birth date, full name and KTN, matches the information you used to enroll in the TTP. Otherwise, the TSA PreCheck® indicator might not show on your boarding pass.

Known Traveler Number FAQ

Still have questions? Here’s more information about KTNs.

Do children need KTNs?

Whether a child needs a KTN depends on their age:

• If the child is 12 or under, they can use TSA PreCheck® lanes with an enrolled parent or guardian. 
• If the child is between 13 and 17 years of age, they must be on the same reservation as an enrolled adult and have the TSA PreCheck® indicator on their boarding pass to use TSA PreCheck® lanes.

The TSA recommends that children who regularly travel alone enroll in TSA PreCheck® and have a KTN. 

How long does it take to get a KTN?

According to the TSA, it typically takes three to five days to receive approval for TSA PreCheck®. But the process can take up to 60 days. The TSA recommends renewing your membership at least 60 days before it expires.

Where is a Known Traveler Number on a Global Entry card?

On a Global Entry card, the Known Traveler Number is the same as the PASS ID number. It can be found on the back of the card in the upper left-hand corner.

Known Traveler Numbers in a nutshell

Where Is The Known Traveler Number On TWIC Card

Published: December 15, 2023

Modified: December 28, 2023

• Travel Essentials & Accessories

Introduction

Traveling is an exciting and enriching experience that allows us to explore new cultures, discover stunning landscapes, and create lifelong memories. However, it’s no secret that navigating through airports and security checkpoints can sometimes be a bit of a hassle. Long lines and tedious procedures can quickly dampen the excitement of embarking on a new adventure.

Thankfully, there are ways to streamline the travel process and make it more efficient. One such tool is the TWIC card, which stands for Transportation Worker Identification Credential. This card is issued by the Transportation Security Administration (TSA) and is primarily intended for individuals who work in the transportation industry, such as truck drivers, port workers, and maritime employees.

However, the TWIC card also offers additional benefits beyond the scope of the transportation industry. One of these benefits is the inclusion of a Known Traveler Number, which allows cardholders to enjoy expedited screening at select TSA checkpoints through programs like TSA PreCheck and Global Entry. By having a Known Traveler Number on your TWIC card, you can bypass the regular security lines and enjoy a more seamless and hassle-free travel experience.

In this article, we will delve into the specifics of both the TWIC card and the Known Traveler Number. You will learn how to obtain a TWIC card, the process of acquiring a Known Traveler Number, and where exactly you can find the Known Traveler Number on a TWIC card. By the end, you’ll be well-equipped with the knowledge to make your future travels smoother and more enjoyable.

What is a TWIC Card?

A TWIC card, which stands for Transportation Worker Identification Credential, is a form of identification issued by the Transportation Security Administration (TSA) in the United States. It was introduced as part of the Maritime Transportation Security Act of 2002, with the goal of enhancing security measures in the transportation industry.

The TWIC card serves as a proof of identity and eligibility for individuals who work in various sectors of the transportation industry, including maritime, trucking, and port facilities. It is a biometric card that contains the cardholder’s personal information, such as their name, photograph, and fingerprint data, which allows for quick and accurate identification.

To obtain a TWIC card, applicants must complete a thorough background check, including a criminal history records check and a security threat assessment. This process helps ensure that only individuals who meet specific eligibility criteria and do not pose a security risk are granted access to sensitive transportation areas.

Once issued, the TWIC card is valid for five years and must be carried by the cardholder at all times while working in secure transportation areas. This includes ports, terminals, vessels, and other designated facilities. Failure to present a valid TWIC card when requested by security personnel can result in restricted access and potentially impact employment within the transportation industry.

In addition to its primary purpose as an identification credential, the TWIC card also provides certain advantages to cardholders. One of these benefits is the inclusion of a Known Traveler Number, which allows for expedited screening at select TSA checkpoints. This allows cardholders to skip the regular security lines and experience a faster and more efficient screening process.

Overall, the TWIC card plays a critical role in maintaining the security and integrity of the transportation industry. It ensures that individuals working in sensitive areas undergo comprehensive background checks and helps facilitate smoother and more secure operations within the maritime, trucking, and port sectors.

What is a Known Traveler Number?

A Known Traveler Number (KTN) is a unique identification number assigned to individuals who have been approved for expedited screening through trusted traveler programs such as TSA PreCheck or Global Entry. This number allows travelers to enjoy a more efficient and streamlined airport security process.

When a traveler applies and is approved for programs like TSA PreCheck or Global Entry, they are assigned a Known Traveler Number. This number is stored in the traveler’s profile and can be used when making flight reservations or updating existing bookings with participating airlines.

The Known Traveler Number is essentially a way for the TSA and other participating agencies to identify individuals who have undergone thorough background checks and are deemed low-risk travelers. By providing their Known Traveler Number during the booking process, travelers can enjoy several benefits:

• Expedited Security Screening: Travelers with a Known Traveler Number are eligible for TSA PreCheck, which allows them to bypass the regular security lines at airports. Instead, they can proceed through special PreCheck lanes where they can keep their shoes, belts, and light jackets on and leave laptops and liquids in their carry-on bags.
• Efficient and Faster Travel Experience: With expedited screening, travelers can save valuable time and avoid the usual inconveniences associated with airport security. They can arrive at the airport later, breeze through security, and have more time to relax or take care of other travel-related tasks.
• Consistent Screening Process: Using the Known Traveler Number ensures a consistent and predictable screening process for travelers. Since they have already gone through thorough background checks, their risk level is considered lower, and they can enjoy a more hassle-free experience at the airport.
• Access to Global Entry: Many travelers with a Known Traveler Number also have access to Global Entry, a program that expedites the customs and immigration process when returning to the United States from international destinations. With Global Entry, travelers can use automated kiosks to complete the necessary forms and skip the long queues at passport control.

It’s important to note that while a Known Traveler Number is associated with a traveler’s profile, it is not printed on any physical document like a passport or driver’s license. However, for individuals who possess a TWIC card, the Known Traveler Number is included on the card itself, making it easily accessible.

Having a Known Traveler Number can greatly enhance the travel experience by reducing wait times, minimizing stress, and allowing travelers to focus on enjoying their journey. By participating in trusted traveler programs and providing their Known Traveler Number when booking flights, individuals can take advantage of expedited screening and enjoy a more efficient and convenient airport experience.

How to Obtain a TWIC Card

Obtaining a TWIC card is a straightforward process that involves several steps. It is important to note that the TWIC card application process requires applicants to visit an enrollment center and undergo a background check. Here is a step-by-step guide on how to obtain a TWIC card:

• Pre-enrollment: Before visiting an enrollment center, applicants must pre-enroll online. This involves providing personal information, such as name, date of birth, and contact details. The pre-enrollment process also requires applicants to schedule an appointment at their preferred enrollment center.
• Prepare the required documents: When visiting the enrollment center, applicants must bring specific documents to verify their identity and work eligibility. These documents typically include a valid government-issued photo ID, proof of citizenship or immigration status, and documentation supporting their employment in the transportation industry.
• Visit the enrollment center: At the scheduled appointment time, applicants must visit the enrollment center they selected during the pre-enrollment process. At the center, they will be required to provide biographic information, have their fingerprints captured, and have their photograph taken.
• Pay the fees: There is a fee associated with obtaining a TWIC card, which can be paid during the enrollment process. Various payment methods, such as credit/debit cards and money orders, are generally accepted. The current fee for a TWIC card can be found on the official TSA website.
• Undergo a background check: The TSA conducts a thorough background check and security threat assessment on all TWIC card applicants. This includes criminal history records, immigration status, and other relevant information. The background check typically takes several weeks to complete.
• Receive the TWIC card: Once the background check is successfully completed, applicants will receive their TWIC card via mail. The card is typically sent to the address provided during the enrollment process. It’s important to ensure that the mailing address is accurate and up to date.

The entire process of obtaining a TWIC card can take several weeks, so it is recommended to apply well in advance of any planned travel or employment start dates. It’s also important to note that the TWIC card is valid for five years from the date of issuance. At the end of the validity period, individuals will need to renew their TWIC card to maintain their authorization for access to secure transportation areas.

By following these steps and providing the necessary documentation, individuals can obtain a TWIC card and enjoy the benefits it offers within the transportation industry. Whether you work in a maritime port, trucking company, or other transportation-related fields, having a TWIC card can help streamline your access to secure areas and facilitate a more efficient and secure work environment.

Where to Find the Known Traveler Number on a TWIC Card

If you have a TWIC card, you may be wondering where to find your Known Traveler Number (KTN) on the card itself. The KTN is a unique identification number that is associated with your enrollment in trusted traveler programs such as TSA PreCheck or Global Entry. While the KTN is not explicitly labeled, it can be found on the TWIC card in the following location:

The Known Traveler Number can typically be found on the back of the TWIC card, towards the bottom. It is usually located in a separate section, often marked as “KTN” or “Known Traveler Number,” followed by a series of alphanumeric characters.

It’s important to note that the placement of the Known Traveler Number on a TWIC card may vary slightly depending on the card’s design and the issuer. Some TWIC cards may have a dedicated space for the KTN, while others may incorporate it into the card’s general information section. However, regardless of the specific placement, the KTN will always be clearly identifiable by the label or title associated with it.

If you are unable to locate your Known Traveler Number on your TWIC card or if there is no designated section for it, it’s advisable to contact the issuing authority or the Transportation Security Administration (TSA) directly for assistance. They will be able to provide guidance and help you locate your KTN on your TWIC card.

Once you have identified your Known Traveler Number, it is recommended to keep a record of it in a safe and easily accessible place. You will need to provide your KTN when making flight reservations or updating existing bookings to ensure you receive the benefits of expedited screening through programs like TSA PreCheck or Global Entry.

By having your Known Traveler Number readily available and providing it when booking flights or updating reservations, you can enjoy the convenience of expedited security screening at select TSA checkpoints. This will help save time, reduce stress, and enhance your overall travel experience by allowing you to bypass the regular security lines and enjoy a more efficient screening process.

Remember, it is essential to protect your TWIC card and the associated Known Traveler Number to prevent unauthorized use or potential identity theft. Treat your TWIC card like any other valuable identification document and keep it secure at all times.

Obtaining a TWIC card and having a Known Traveler Number can greatly enhance your travel experience, both within the transportation industry and at the airport. The TWIC card serves as a valuable form of identification for individuals working in various sectors, ensuring security and integrity within the industry.

With the inclusion of a Known Traveler Number on the TWIC card, cardholders can enjoy the benefits of expedited screening and a more streamlined airport experience. By participating in trusted traveler programs like TSA PreCheck or Global Entry, individuals can bypass regular security lines, keep their belts and shoes on, and enjoy a more efficient and stress-free screening process.

The process of obtaining a TWIC card involves pre-enrollment, visiting an enrollment center, undergoing a background check, and paying the associated fees. Once approved, the TWIC card will be issued, and it is valid for five years. Remember to keep the card secure and always carry it when working in secure transportation areas.

To find your Known Traveler Number on a TWIC card, look for a designated section on the back of the card marked as “KTN” or “Known Traveler Number,” followed by a series of alphanumeric characters. If you have difficulty locating your KTN, reach out to the issuing authority or the TSA for assistance.

By taking advantage of the benefits provided by a Known Traveler Number, you can transform your travel experience, save time, and reduce stress at the airport. With expedited screening, you can focus on enjoying your journey and spend less time dealing with lengthy security processes.

Whether you work in the transportation industry or plan on traveling frequently, a TWIC card with a Known Traveler Number can be a valuable asset. It ensures your identity and eligibility for secure areas while also providing expedited screening privileges at select TSA checkpoints.

So, don’t let airport security procedures slow you down. Apply for a TWIC card, acquire a Known Traveler Number, and enjoy the benefits of a more efficient and hassle-free travel experience.
