Air travel can be stressful even on the smoothest of days. Between checking luggage, finding gates, and keeping track of flight times, passengers already have a lot on their plates. Unexpected delays, long security lines, or additional procedures can make the experience even more overwhelming. One detail that often surprises travelers is a small, four-letter code printed on their boarding pass—something most people don’t notice until they reach the airport.
That code, “SSSS,” stands for Secondary Security Screening Selection. It indicates that a passenger has been chosen for additional screening by the Transportation Security Administration (TSA). This is part of the TSA’s Secure Flight program, a risk-based pre-screening system designed to identify both low-risk and higher-risk travelers before they reach the checkpoint. The system compares passenger information—such as full name, date of birth, and gender—against trusted traveler lists and federal watchlists to ensure airport security remains strong.
