What Is the Thailand Digital Arrival Card (TDAC)?
The TDAC is an online form that every traveller must complete before entering Thailand. It collects information such as your personal details, flight number, accommodation, and health status. This digital system replaces the paper TM6 form that was handed out on planes or at border checkpoints.
This is part of Thailand’s move towards a more digital and efficient immigration process. Submitting the TDAC online will help speed up your entry and reduce queues at immigration counters.
TM6 form Thailand
The TM6 immigration form was a mandatory paper-based arrival and departure card that all foreign travellers entering or leaving Thailand were required to complete. Typically distributed by airline staff during international flights, the form collected essential information such as personal details, passport information, flight numbers, and accommodation addresses. Upon arrival, travellers would submit the completed form to immigration officers, who would retain the departure portion for collection upon exit.
Suspension of the TM6 Form
Thailand suspended the requirement for air travellers to complete the TM6 form. This decision aimed to streamline the immigration process, reduce congestion at airports, and enhance the overall travel experience for visitors. Thailand is now replacing the old paper form with the new digital arrival card. This is known as the TDAC. It is short for Thailand Digital Arrival Card.
Who Needs to Submit the TDAC?
Effective May 1st, 2025, the TDAC must be completed by all foreign travellers entering Thailand by air, land, or sea.
The only exceptions are:
✅ Transit passengers who do not go through immigration
✅ Travellers with a valid border pass
✅ Thai citizens
For all other travellers, submitting the TDAC is now a mandatory step before arriving in Thailand.

When Should You Submit the TDAC?
You must submit the TDAC within 3 days before your arrival in Thailand. This includes the day you arrive. Submitting it too early is not allowed, and the system will not let you choose a date outside this 3-day window.
For example:
- If you are arriving in Thailand on 31st May, you can submit your TDAC any time between 29th and 31st May.
- You cannot submit it earlier than 29th May in this case.
This means you should mark your calendar and make sure to complete the TDAC at least one day before you fly, just in case of internet problems or other issues.
What Information Do You Need to Submit?
Before you start filling out the TDAC, make sure you have the following details ready:
- Your passport number and expiration date
- Your flight number and arrival date/time
- The address of your accommodation in Thailand (hotel, guesthouse, Airbnb, etc.)
- Your contact details (email and phone number)
- A simple health declaration
It takes only about 5–10 minutes to fill out the form if you have everything prepared.
Step-by-Step: How to Submit the TDAC
- Go to the official website: TDAC Immigration
- Choose your language and start the application.
- Enter your personal and travel information.
- Review everything to make sure it’s correct.
- Submit the form.

Final Tips Before You Travel
- Don’t wait until the last minute. Submit the TDAC three days before your flight.
- Double-check all the information you enter.
- Save or print the QR code you receive.
- Keep the QR code ready to show at immigration counters upon arrival
