What Is My Known Traveler Number (KTN)?

A Known Traveler Number (KTN) is a unique identification number issued by the Transportation Security Administration (TSA) in the United States. It is part of the TSA PreCheck program, which is designed to expedite the security screening process for eligible travelers when flying domestically within the United States. Here’s everything you need to know about your Known Traveler Number:

1. TSA PreCheck Program:

• The TSA PreCheck program is a trusted traveler program that allows pre-screened travelers to enjoy expedited security screening at participating U.S. airports. This means shorter lines, no need to remove shoes, belts, and laptops, and a generally more efficient airport experience.

2. Eligibility:

• To be eligible for TSA PreCheck, travelers must meet specific criteria. U.S. citizens and lawful permanent residents can apply, as well as some foreign nationals. Eligibility is also extended to members of certain other trusted traveler programs like Global Entry and NEXUS.

3. Application Process:

• To obtain a Known Traveler Number, eligible individuals must complete an application and undergo a background check. This process involves providing personal information, fingerprints, and documentation to confirm identity and citizenship or lawful permanent resident status.

4. Interview:

• After submitting the application, applicants are typically required to attend an in-person interview at an Enrollment Center. During the interview, they will answer questions and have their fingerprints taken.

5. Approval and KTN Assignment:

• Upon successful completion of the application and background check, applicants are approved for TSA PreCheck and assigned a Known Traveler Number (KTN). This number is unique to the individual and is used to identify them in the TSA PreCheck system.

6. Using Your KTN:

• Travelers with a KTN can provide this number when booking flights or entering it in their frequent flyer profiles. When the KTN is associated with a flight reservation, the traveler is eligible for TSA PreCheck screening.

7. Benefits of TSA PreCheck:

• Travelers with TSA PreCheck enjoy expedited security screening, which can save valuable time at the airport. They also benefit from not having to remove their shoes, belts, lightweight jackets, or laptops from carry-on bags.

8. Validity:

• A Known Traveler Number is typically valid for five years. Travelers must renew their TSA PreCheck membership before it expires to continue enjoying the benefits.

9. International Travel:

• While TSA PreCheck primarily applies to domestic U.S. flights, some international airlines and airports also participate in the program, offering expedited security screening for eligible travelers departing to international destinations.

In conclusion, a Known Traveler Number (KTN) is a valuable credential that allows travelers to experience a more efficient and convenient airport security process when flying within the United States. It simplifies the travel experience and is especially beneficial for frequent travelers or those who value convenience and time savings at the airport.
