What Is TSA PreCheck?

TSA PreCheck is a U.S. government program that allows travelers deemed low risk by the Transportation Security Administration (TSA) to pass through an expedited security screening at certain U.S. airports.

The application process for TSA PreCheck can be started online, but an in-person background check must also be conducted.

Qualifying travelers don’t have to remove their belts, shoes, or lightweight jackets. They may also leave a laptop in its case and a 3-1-1 compliant bag (which can contain items with small quantities of liquids and gels, such as a travel-size bottle of mouthwash) in their carry on luggage.

How TSA PreCheck Works

The program is intended to speed up the passage of verified travelers through security checkpoints, which may become crowded as passengers gather to board their flights. Typically passengers must remove articles of clothing and personal items that could be used to contain hazardous materials.

Shoes, for example, were previously used in attempts to smuggle and detonate explosives on an airplane. Electronic equipment such as laptops are also usually subject to scrutiny at checkpoints because of attempts to hide materials inside by removing components.

Key Takeaways

  • TSA PreCheck is a way to clear passengers who have been vetted and confirmed in advance, allowing for swifter passage through security checkpoints and shortening the lines other passengers must wait in.
  • An application process can be started online but an in-person background check is also required.
  • Once approved, travelers receive a Known Traveler Number (KTN), which is valid for five years.

Some 200 airports and 65 airlines offer this service. You can apply directly to the TSA. You will have to visit one of the more than 380 application centers where you will be fingerprinted and asked for valid identity and citizenship information. There is an $85 non-refundable application fee. Travelers who are foreign citizens must meet certain residency requirements in order to qualify for the program.

The Department of Homeland Security operates other federal programs such as Global Entry, NEXUS, and SENTRI for verifying the identities of trusted travelers. The NEXUS program covers pre-screened travelers who are traveling between Canada and the U.S. The SENTRI program governs travel on land into the U.S. from Mexico. Global Entry lets trusted travelers who are traveling internationally quickly move through customs and border protection.

Once approved, you will receive a Known Traveler Number (KTN). Use that number any time you book a flight. The KTN is valid for five years. When you have your KTN, you can use a faster line at participating airports reserved for TSA pre-passengers.
