Starting May 1st, 2025, all foreign nationals entering Thailand by air, land, or sea must complete the Thailand Digital Arrival Card (TDAC) electronically three days before arrival.
Completion of the TDAC will be mandatory for all foreign passport holders, including tourists, business travelers, and long-term residents. Exceptions apply only to travelers transiting or transferring through Thailand without passing through immigration control and to those entering using a Border Pass.
To register the TDAC, travelers should visit the Thailand Immigration Bureau’s official website: https://tdac.immigration.go.th or scan the QR code above.
