What is the TDAC?
The TDAC is Thailand's online entry form. It replaced the paper TM6 form on 1 May 2025. Every foreign national entering Thailand by air, land or sea submits one for each trip, within the 3 days before arrival, with passport, travel, accommodation and health details. The TDAC is not a visa: check separately whether your passport needs one.
What you need
- Your passport, valid for at least 6 months from arrival
- Your arrival date and flight number (or how you arrive by land or sea)
- The address where you stay in Thailand
- An email address you can open on your trip
Who needs a TDAC?
All foreign nationals entering Thailand, children and infants included (a parent or guardian fills it in for them). Under the official rules you do not need one if you are:
- Transiting or transferring through Thailand without passing immigration control
- Entering Thailand with a Border Pass
Applying more than 3 days ahead? No problem: we keep your application and submit it as soon as the official window opens.
Thailand TDAC: questions and answers
Is the TDAC free?
Yes, if you submit it yourself on the official Thai Immigration website. Our price is for our service: we fill in your TDAC from one short form, a person checks it against your passport, we submit it in the right window and send you the confirmation. You see the full price before you pay.
When must the TDAC be submitted?
Within the 3 days before you arrive in Thailand, the day of arrival included. You can apply with us earlier: we keep your application and submit it as soon as the window opens.
How late can I apply?
Our form takes arrival dates from tomorrow onwards. The sooner you apply, the more time we have to check your details and sort out anything that does not match your passport.
Do children need their own TDAC?
Yes. Every traveller needs their own TDAC, children and infants included. A parent or guardian fills it in for them.
Do I need a new TDAC for every trip?
Yes. A TDAC covers one entry on the arrival date you give. Each new trip to Thailand needs a new one.
Do I need a TDAC if I only change planes in Bangkok?
Not if you stay airside and do not pass immigration control. If you leave the airport or go through immigration, you need one.
Is the TDAC a visa?
No. The TDAC is an entry form, not a visa. Depending on your passport and the length of your stay, you may also need a visa.
How do I get my TDAC?
We email the confirmation with its QR code to the address you give in the form. Keep it on your phone when you land. A printed copy is a good backup.
My travel plans changed. What now?
Write to us as soon as you can with your reference number. Before we submit, we simply update your application. After submission we help you correct the details.
