What Is a TSA Precheck Number?

A TSA Precheck number, also known as a Known Traveler Number (KTN), is a unique identification number assigned to individuals who have been approved for TSA Precheck. TSA Precheck is a program by the Transportation Security Administration (TSA) that allows eligible travelers to enjoy expedited screening at participating airports in the United States.

Definition of a KTN

A Known Traveler Number (KTN) is a 9-digit number issued to travelers who have successfully enrolled in TSA Precheck. This number serves as a way to identify individuals who have gone through an extensive background check and are considered low-risk travelers.

By providing your KTN at the time of booking or during the check-in process, you can ensure that you will be eligible for TSA Precheck benefits.

Who Needs a Precheck Number

Anyone who wishes to enjoy the benefits of TSA Precheck, such as expedited security screening and not having to remove shoes, laptops, liquids, belts, and light jackets, will need a TSA Precheck number. It is important to note that not all travelers are automatically eligible for TSA Precheck.

To be eligible for TSA Precheck, individuals must meet certain criteria, such as being a U.S. citizen or Lawful Permanent Resident, passing a background check, and not having any disqualifying criminal convictions.

Additionally, travelers who are members of certain trusted traveler programs, such as Global Entry or NEXUS, are automatically eligible for TSA Precheck.

To obtain a TSA Precheck number, individuals must apply for TSA Precheck and complete the enrollment process. Once approved, they will be issued a KTN, which they can then use when booking flights or updating their traveler profiles with participating airlines.
