If you’ve ever noticed “SSSS” printed on your boarding pass, you might wonder what it means and why it’s there. This four-letter code stands for “Secondary Security Screening Selection,” which means the TSA has chosen you for additional security checks before you board your flight. These checks are more detailed than the usual screening and can take extra time.
The TSA doesn’t publicly explain exactly how they decide who gets “SSSS,” but factors like traveling to certain countries often, buying last-minute one-way tickets, paying with cash, or having a name similar to someone on a watchlist can increase your chances. Sometimes, passengers are selected randomly to keep security unpredictable.
When your boarding pass shows “SSSS,” be ready for extra steps at the checkpoint. This can include a thorough pat-down, a closer look at your carry-on and checked bags, and tests for explosive materials. TSA officers might also ask you more questions about your travel plans. Because of this, it’s best to arrive at the airport early to avoid rushing.
To reduce the chance of being selected, consider joining trusted traveler programs like TSA PreCheck or Global Entry, which involve background checks and can speed up security. Also, try to keep your travel plans consistent and avoid buying last-minute one-way tickets. If you believe you’ve been repeatedly chosen unfairly, you can request help through the DHS Traveler Redress Inquiry Program.
Knowing the meaning of “SSSS” and what happens during secondary screening can help you stay calm and prepared, making your airport experience smoother.
