TDAC before you fly: the free Thailand Digital Arrival Card checklist
Since 1 May 2025, every non-Thai national entering Thailand by air, land or sea must file a Thailand Digital Arrival Card. It is free and takes about 5 minutes.
Rules from the Immigration Bureau TDAC FAQ. Checked 29 October 2026.
The rules
- Who: every non-Thai national, including children and infants, and visa-exempt travellers.
- When: within 3 days before arrival, counting the arrival day.
- Where: only the Immigration Bureau site, tdac.immigration.go.th.
- Cost: free. Sites that charge a fee are not official.
- Once per entry: a TDAC is single use. File a new one for every trip into Thailand.
Have these ready
- Passport details
- Flight number and arrival date
- Your first address in Thailand, such as the hotel name
- Travel purpose and a short health declaration
- An email address to receive the TDAC
Good to know
- Transit only: if you do not pass immigration, you do not need one.
- Plans changed: you can update or resubmit before you enter. The latest entry counts.
- No reminders: the system does not email you before your trip, so set your own.
- Not a visa: the TDAC does not change visa or visa exemption rules. Check those separately.
