Thailand Digital Arrival Card (TDAC) - What You Must Complete Before Flying to Bangkok
The one form you really don’t want to fill out at the airport

Bangkok , Thailand
As of 2026, the Thailand Digital Arrival Card Get Your Thailand Digital Arrival Card (TDAC)is mandatory for entry. You must complete it online within 3 days before your flight.
It replaced the earlier ETA proposal, so this is now the official system.
The process itself is simple and takes only a few minutes. But do not leave it until you are standing at the check-in counter. We saw people trying to complete it while a line was building behind them.
Fill it out at home, calmly. Screenshot the confirmation. It’s a small step that makes arrival smooth.
