How to Find Your Known Traveler Number (KTN)

A Known Traveler Number (KTN) is a unique identification number issued by trusted traveler programs, such as TSA PreCheck or Global Entry, to travelers who have undergone pre-screening and background checks. Having a KTN can help expedite your airport security screening process, making travel more efficient. Here’s how to find your Known Traveler Number:

1. Check Your Trusted Traveler Program Approval Email:

• If you applied for TSA PreCheck, Global Entry, NEXUS, or SENTRI and were approved, you should have received an approval email or letter. Your Known Traveler Number is usually included in this correspondence.

2. Log into Your Trusted Traveler Program Account:

• Visit the website of the trusted traveler program you applied for (e.g., TSA PreCheck, Global Entry) and log into your account using your username and password. Once logged in, you may be able to find your KTN in your profile or account information.

3. Contact the Program’s Customer Service:

• If you can’t find your KTN through the program’s website, you can contact their customer service or support team for assistance. They can provide you with your KTN after verifying your identity.

4. Check Your Membership Card:

• If you were approved for a program like Global Entry, you may have received a physical membership card. Your KTN might be printed on this card.

5. Visit an Enrollment Center (Global Entry Only):

• For Global Entry members, you can visit a Global Entry Enrollment Center for assistance. They can verify your identity and provide you with your KTN if needed.

6. Review Your Airline Reservation:

• If you have previously added your Known Traveler Number to your airline reservation, it may be visible on your boarding pass or in your reservation details.

7. Check Previous TSA PreCheck Boarding Passes:

• If you have used TSA PreCheck in the past, your Known Traveler Number may be printed on previous TSA PreCheck boarding passes.

8. Contact Your Airline:

• If you have trouble finding your KTN, you can contact the airline you frequently travel with. They may have it on record if you provided it during booking.

9. Retrieve Your SENTRI or NEXUS Card (SENTRI and NEXUS Members):

• If you are a SENTRI or NEXUS member, your KTN may be found on your SENTRI or NEXUS membership card.

It’s important to keep your Known Traveler Number handy, as you’ll need to enter it when making flight reservations to ensure you receive the benefits of expedited security screening. Additionally, remember to verify the expiration date of your trusted traveler program membership, as you’ll need to renew it to maintain access to your KTN and its associated privileges.
