Skip to content The code SSSS stands for Secondary Security Screening Selection, a procedure used by the Transportation Security Administration (TSA) to enhance airport security. Passengers who receive this designation are asked to complete additional screening before boarding their flight. These extra checks may include a more detailed inspection of carry-on luggage, testing electronic devices, verifying identification, or conducting a routine pat-down. Because airlines typically do not notify passengers ahead of time, the additional screening often comes as a surprise. Although the process may take a little longer than standard security, it is designed to be thorough while helping maintain the safety of everyone traveling through the airport.
