All About SFO Security Checkpoints & How It Works
Security checkpoints are at the stand at the entrance to each boarding area, and only ticketed passengers may pass beyond them. SFO airport has 6 main security checkpoints for passengers to complete their screening at the kiosks. Along with the general lanes, every checkpoint provides TSA PreCheck®, Priority Line, and CLEAR lanes. Security does not allow baggage carts through the screening area.
Passengers may enter through any checkpoint in any terminal as long as they carry a same-day boarding pass to travel under TSA rules. After they pass through security, they can walk to any gate in the airport.
Arriving international passengers who connect to onward flights must complete the federal inspection process, exit the secure area, and go through security again. International flights with preclearance may skip the federal inspection process.
