What is TSA PreCheck®?

TSA PreCheck®, like Global Entry, NEXUS and SENTRI, is a Trusted Traveler Program offered by the Transportation Security Administration (TSA) that can help you move through airport security faster. 

Becoming a TSA PreCheck® member requires an application, in-person appointment and enrollment fee. Upon approval, you get a Known Traveler Number (KTN). By adding the KTN to your flight reservations, you can enjoy shorter security lines and an easier screening process at over 200 airports and 90 airlines.

Some travel credit cards, like Capital One’s Venture, Venture X, Spark Miles and Venture X Business cards, will reimburse cardholders’ TSA PreCheck® or Global Entry application fee with a statement credit up to $100.*

What if TSA PreCheck® isn’t on your boarding pass?

It’s a good idea to add your KTN when booking a flight so that it shows up on your boarding pass. But if you forgot to add your KTN or it’s not shown on your boarding pass, there are a few things you can do.

You can contact the airline to add your KTN after booking or make sure you entered your name, date of birth and KTN correctly. If your KTN still doesn’t show up, consider checking that your TSA PreCheck® membership is active. You can also submit an online form or call the TSA at (866) 289-9673.

Can you add TSA PreCheck® after booking?

If you didn’t include your TSA PreCheck® number when booking a flight, it’s possible to add it later. You can usually add it through the airline’s mobile app or contact the airline online or by phone to add it to a reservation.

Can you add your KTN to an existing reservation?

TSA issues each TSA PreCheck® member a KTN that grants access to expedited security lines. So adding a KTN to an existing reservation is the same as adding TSA PreCheck® after booking.
