A Transportation Security Administration (TSA) Known Traveler Number (KTN) is a unique identifier assigned to pre-approved, low-risk air travelers who have undergone a thorough background check by the TSA. For example, frequent flyers or individuals with sensitive occupations may qualify for a KTN.
KTNs streamline the airport screening process by allowing pre-approved travelers to bypass certain security procedures, such as removing shoes and emptying liquids. Benefits include expedited security checks, reduced wait times, and a smoother overall travel experience. The implementation of the KTN program in 2005 marked a significant advancement in airport security.
