How do I add TSA PreCheck before boarding?

A Known Traveler Number (KTN) is issued to all individuals approved to receive TSA PreCheck® expedited screening. The KTN must be added in the KTN field when booking airline travel reservations to have the TSA PreCheck® indicator appear on your boarding pass.

Yes. TSA PreCheck® is available when you depart from a U.S. airport to a foreign country, and for domestic, connecting flights after you return to the United States. If you travel internationally four or more times a year, consider enrolling in Global Entry instead of TSA PreCheck®.

Yes! In short, the TSA states: “To receive TSA PreCheck, you must include your Known Traveler Number (your CBP PASSID for Global Entry, NEXUS, or SENTRI members) in the appropriate field of your airline reservation, and the TSA PreCheck® indicator must be displayed on the boarding pass to access the lanes.”

If you are unclear why you are not receiving the TSA PreCheck® indicator on your boarding pass, first check that your membership has not expired by looking up your KTN (Known Traveler Number) here. If your KTN is still active, confirm with your airline that your KTN, name, and date of birth are accurate.

MORE DETAILS

Your “Known Traveler ID” from the TSA has to be added to your account at each airline you use — it's not automatic. Once that's done and enough time has passed so that it's fully in the airline's system (a few days, it's not immediate), that should trigger the appearance of the pre-check status on your boarding pass.

MORE DETAILS

Go to the TSA PreCheck website and select the tab that says “Renewal” to begin the process. Provide your KTN, date of birth and legal last name. You'll then be guided through a series of screens that will ask you to confirm your address and passport information and answer some security questions.

Can you bring a guest through TSA PreCheck? Usually, no, but there are exceptions. These include allowances for the following types of guests who don't have their own TSA PreCheck membership: spouses, children, those with a disability, and active military personnel. There are also rules for pets.

MORE DETAILS

No. The system checks your KTN against the name, gender, and birthdate on the ticket. The system will let you add any number you want, but the boarding pass will never actually show the symbol if the number doesn't match the ticketholder.
