Can I use e-gates in Thailand with a new passport after entering visa exempt previously?

Rules for Using Thai e-Gates

• Same Passport Required: You must have previously entered Thailand using the exact same passport so your biometric data (fingerprints and facial image) is already stored in the Thai Immigration system.

• New Passport Process: If you have a brand-new passport (even if you are a citizen of one of the 33 eligible nationalities), your biometric record is not linked to it yet.

• First-Time / New Document Check: You must go through a staffed immigration counter on your first entry with a new passport to register your biometrics. Once that entry is logged, you can use the e-gates on future trips with that same passport.

• Be a citizen of an eligible nationality (open to 33 specific countries at Bangkok Suvarnabhumi Airport).

• Enter Thailand on a visa-exempt (visa-free) status rather than holding a physical visa or long-stay permit.

• Submit a completed Thailand Digital Arrival Card (TDAC) before arrival.

You can no problem. Passport Not important

As Graham said no. Its because biometric data and previous history will not match to the new one.

New passport needs to be stamped for your first entry with it
