What Is a Known Traveler Number (KTN) & How to Find Yours?

If you are a member of a Trusted Traveler Program (TTP), you will receive a Known Traveler Number (KTN)—a unique nine-digit identifier, usually starting with 98. This number grants you access to TSA PreCheck® and Global Entry lanes, helping you move through airport security and customs more quickly.

Benefits of a Trusted Traveler Program (TTP)

Trusted Traveler Programs offer:
Expedited airport security screening with TSA PreCheck®
Faster re-entry into the U.S. through customs and border control
Convenient travel processing for frequent domestic and international travelers

Types of Trusted Traveler Programs

The Department of Homeland Security (DHS) offers several TTPs, including:

  • Global Entry – For international travelers re-entering the U.S.
  • NEXUS – For travelers between the U.S. and Canada
  • SENTRI – For travelers between the U.S. and Mexico
  • TSA PreCheck® – For expedited security screening within the U.S.

How to Find Your Known Traveler Number (KTN)

Your KTN is assigned once you are approved for a Trusted Traveler Program. Depending on your membership, you can locate it as follows:

Global Entry, NEXUS, or SENTRI Members: Find your KTN on the back of your membership card or by logging into your account on the Trusted Traveler Program website.
TSA PreCheck® Members: Your PASS ID serves as your KTN and can be found in your TSA PreCheck® online account.

How to Use Your KTN When Traveling

To take advantage of TSA PreCheck® and Global Entry benefits, enter your Known Traveler Number (KTN) when booking flights. Most airlines have a designated field for your KTN or PASS ID during the reservation process.

By ensuring your KTN is linked to your airline reservations, you can enjoy seamless faster airport security and customs processing.
