I forgot my Known Traveler Number (KTN). How do I find it?

If you are a member of the TSA PreCheck® Application Program, look up your Known Traveler Number (KTN) here.

 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 is your KTN.

If your TSA PreCheck® benefits come through HME, TWIC®, or DoD, please visit these respective links for additional information: HME, TWIC®, DoD.

If your TSA PreCheck® benefit comes through TSA PreCheck® for DHS employees, please visit TSA PreCheck® for DHS Employees | TSA PreCheck® for additional information.
