Can you share your KTN with someone else?

Officially, Known Traveler Numbers (KTNs) belong to a person, so every traveler needs their own KTN so long as they are 13 or older.



No, you cannot share your Known Traveler Number (KTN) with someone else. A KTN is a unique identifier issued by the TSA to individuals who have been vetted through programs like TSA PreCheck, Global Entry, NEXUS, or SENTRI. This number is tied directly to your biometric data, your legal name, and your government-issued identification. If you attempt to use someone else’s KTN on a flight reservation, or let someone else use yours, the TSA’s secure flight system will detect the "data mismatch" between the number and the traveler’s name. This will result in the "TSA PRE" indicator being removed from the boarding pass, and in more serious cases, it could lead to a permanent revocation of your PreCheck or Global Entry status. In 2026, the TSA has further strengthened these protocols using facial recognition at many checkpoints to ensure the person in the PreCheck lane is the person to whom the KTN was issued. Each traveler, including children over a certain age (usually 13 to 17 depending on the airline), must have their own vetting and their own KTN to use the expedited security lanes.
