Thailand replaced its paper arrival form with the Thailand Digital Arrival Card (TDAC). Whether you travel visa-free or with a visa, you will most likely need to submit it online before you arrive.
Who needs the TDAC?
Most foreign nationals entering Thailand by air, land or sea – including visa-exempt travellers. Thai citizens and certain transit passengers who do not pass immigration are exempt.
When should I submit it?
Submit it within 3 days before your arrival (including the day of arrival). You cannot submit it weeks in advance, so set a reminder.
What you need
- Your passport details
- Flight number and arrival date
- Your accommodation address in Thailand
- Your email address
- Basic health declaration information
Step by step
- Go to the official TDAC website of the Thai Immigration Bureau (it is free – avoid sites that charge a fee).
- Fill in your personal, travel and accommodation details.
- Check that your passport number and name exactly match your passport.
- Submit and save the confirmation (a QR code or reference is sent to your email).
- Keep it on your phone – immigration may ask to see it.
Watch out for fake sites. The official TDAC is free. Websites that charge "processing fees" are not required.
Common mistakes
- Submitting too early (more than 3 days before arrival)
- Typos in passport number or name
- Using a hotel address that doesn't match your booking
Do I still need a visa?
The TDAC is not a visa. Check whether your passport is visa-free for 30 days or needs an e-Visa in our Thailand visa guide, or let us handle your Thai visa.
