After this, the provider will collect your payment of $78. First-timers need help to apply and pay online. The websites that do not end in gov aren’t TSA PreCheck’s official website. Upon the approval of your application, you will get a KTN (Known Traveler Number) that you must include in your airline’s reservation details to ensure quick screening during security checks.

  1. If it doesn’t auto-populate, you can include it during flight booking. The KTN field is in the airline’s Who’s Flying section, under Secure Traveler Information, where you must manually enter the number.


When you enrol for a TSA PreCheck, you get the benefit of quick screening without having to open your shoes, light jacket, or belt during security checks.
