Seeing “SSSS” printed on your boarding pass can be confusing and even nerve-wracking for travelers. This code stands for “Secondary Security Screening Selection,” which means the TSA has selected you for extra security checks beyond the normal screening.
The TSA doesn’t reveal all the exact factors that lead to an “SSSS” flag, but it often involves things like unusual travel routes, purchasing last-minute or one-way tickets, paying with cash, or sharing a name similar to someone on watchlists. Sometimes, it’s just a random selection.
If you have “SSSS” on your pass, be ready for more detailed screening. This includes thorough pat-downs, additional luggage inspections, possible swabbing for explosives, and more questions about your travel. Because of this, allow extra time when getting through security.
You can reduce your chances by enrolling in Trusted Traveler programs like TSA PreCheck or Global Entry, although these don’t guarantee avoidance of secondary screening. If you feel you’ve been unfairly chosen multiple times, you can submit a complaint through the DHS Traveler Redress Inquiry Program (DHS TRIP).
Knowing what “SSSS” means and what to expect can help you stay calm and prepared, making your airport experience smoother despite the extra precautions.
