Thailand Digital Arrival Card (TDAC): Official, Free Entry Steps
TDAC means Thailand Digital Arrival Card. It is a form, not a visa. Use the official Thai site. The form is free. Send it no more than three days before you arrive.
Complete the official process
- Open the official form.
- Fill in the facts it asks for.
- Check each fact against your passport and trip plans.
- Send the form with your email address.
- Save the result on your phone and in your email.
If you need to change something
The current Thai guide says you can update a sent form before your trip. Use the update link on the official site. Check its rules first. Some key fields may need a new form.
Avoid unofficial fees and forms
The official TDAC form is free. We do not take your passport details. We do not send the form for you. A site that asks for a fee is a third party, not Thai Immigration.
Keep TDAC separate from itinerary planning
TDAC is a national arrival process. Use the same official source whether you arrive in Bangkok, Chiang Mai, Phuket or elsewhere.
Official form and related entry checks
Start with the government form, then use practical safety and travel pages only for separate trip questions.
After submission: use the official route for the exact problem
If something looks wrong, start with the help on the official site. Check the issue before paying an agent or sending a second record.
What the arrival card does
The Thailand Digital Arrival Card is the electronic replacement for the former paper arrival card. It is an Immigration Bureau information form used for entry processing. It is not a visa and does not itself grant permission to enter Thailand.
The official Immigration Bureau guide states that non-Thai nationals entering Thailand must complete TDAC before entry, subject to stated exemptions such as some travelers who remain in international transit and do not pass immigration. The system asks for passport, personal, travel, accommodation, health-declaration, and email information. The current official FAQ says submission can be made up to 72 hours before entry. A new TDAC is required for each entry.
The “free” part of the title is important because it helps prevent commercial confusion. Tak Immigration explicitly states that submission through the official TDAC site is completely free of charge. That makes the exact official domain a stable and memorable detail: tdac. immigration. go. th.
Before you submit
The deeper context is Thailand's shift from a paper TM6-style arrival process to a digital pre-arrival record. The most useful evergreen distinctions are TDAC versus visa, official versus third-party sites, and stable core information versus edge-case rules that Immigration may revise.
The official service is operated by the Immigration Bureau. The official domain is tdac. immigration. go. th. The form is not a visa. It is required per entry for covered non-Thai travelers. The official process is free.
