What does TSA look for when they check your ID?

The TSA officer may ask you to complete an identity verification process which includes collecting information such as your name, current address, and other personal information to confirm your identity. If your identity is confirmed, you will be allowed to enter the screening checkpoint.



When a TSA officer checks your ID in 2026, they are verifying three primary things: authenticity, identity, and flight eligibility. First, they use Credential Authentication Technology (CAT) scanners to ensure the ID is not a forgery and contains the correct security features (like the REAL ID star). Second, they perform a "visual match" to ensure the person standing in front of them is the same person in the photo; in many airports now, this is supplemented by facial recognition cameras that match your live face to your government-held passport or ID photo. Finally, the system cross-references your ID with the Secure Flight database to confirm you have a valid boarding pass for a flight departing that day and that you are not on any high-risk watchlists. They are also looking for signs of tampering, such as altered dates or names, to ensure the document has not been compromised.
