What “SSSS” Stands For
SSSS = Secondary Security Screening Selection
It’s not a personal accusation.
It’s not proof you’re suspicious.
It’s not even about you, necessarily.
It’s a random or algorithm-driven flag used by the TSA (Transportation Security Administration) as part of the Secure Flight program—a system designed to:
Enhance aviation security
Identify potential threats before boarding
Match passenger data against government watchlists and trusted traveler databases
If your name matches certain patterns—or is randomly selected—you get the SSSS tag, which means:
You’ll undergo additional screening at the checkpoint.
