Why did I get an SSSS on my boarding pass? SSSS stands for Secondary Security Screening Selection. It’s a tag printed on your boarding pass to indicate that you have been selected to receive additional enhanced screening of your body and your personal items like carry-on baggage at the airport — either at the initial TSA screening area or the boarding gate.
