Official cost
No fee
Submit on the Thailand Immigration Bureau domain, not a paid lookalike.
No-fee arrival card · not a visa
Thailand TDAC.
One official route.
Submit within three days before arrival on the Immigration Bureau domain.
Prepare your passport, Thai arrival details and first accommodation address. This guide turns the official form into a calm sequence and helps you avoid paid lookalikes.
The short answer
Required before immigration. Still not a visa.
The Thailand Digital Arrival Card replaces the paper arrival card for non-Thai travellers. It records an arrival; it does not create permission to stay or replace a visa check.
Submission window
Within 3 days
The official FAQ includes your arrival date in that window.
Validity
One entry
Submit a new TDAC for every new arrival in Thailand.
Official estimate
About 3–5 min
That estimate assumes your passport, journey and first address are ready.
Your TDAC and permission to enter are separate decisions. Check the current Thailand visa and entry rules, and use the dedicated tourist visa guide when your stay or passport needs a visa.

Trip.com and 12Go are affiliate links for an accommodation or journey you genuinely need. They do not submit, approve or influence your TDAC, which remains free on the official site.
When the journey differs
Four situations that change the route.
The useful question is not which visa label you have. It is whether a non-Thai traveller will pass Thai immigration on this arrival.
Children
Every traveller needs a record
The official FAQ includes infants and children. A parent may submit on their behalf.
Family or group
Up to 10 in one submission
The group route can reuse shared journey and accommodation information.
Air, land or sea
The mode does not remove the rule
Non-Thai travellers entering through immigration submit before arrival.
Airside transit
No immigration, no TDAC
The official FAQ says it is not required if you remain in transit and do not pass immigration.
Mistake or itinerary change?
Repair the record before entry.
A different hotel, flight or passport typo needs a calm correction. The official site provides an update route and explains when to submit a new form.
01
Open Update Arrival Card
Retrieve the submission using the identifiers requested by the current form.
02
Correct available fields
Then review the full journey and accommodation record again.
03
Otherwise submit again
If that field cannot be edited, the latest valid submission is the one used.
Final checkpoint
English details. Correct domain. QR code offline.
The official guide asks for details in English. Recheck anything read from an MRZ scan and keep the downloaded document or email available through your arrival.
Verbatim search questions
Thailand TDAC FAQs
These are real English People Also Ask questions captured on 26 July 2026. Answers follow the current Thailand Immigration Bureau guide and FAQ.
Is it necessary to fill a Thailand Digital Arrival Card?
Yes for non-Thai nationals who enter Thailand and pass immigration by air, land or sea. The official exceptions include crew and travellers who remain in transit without passing immigration. The TDAC is an arrival form, not a visa or permission to stay.
How do I get a digital arrival card for Thailand?
Use only tdac.immigration.go.th. Choose Arrival Card, enter your passport, personal, journey, first-accommodation and any requested health information, review the preview, submit and download the document with QR code.
How many days before we can fill TDAC Thailand?
The Immigration Bureau says to submit within three days before arrival, including the arrival date. The calculator on this page turns that rule into three calendar dates using the Thai arrival date on your itinerary.
Does it cost to get a Thailand Digital Arrival Card?
The official Thailand Immigration Bureau submission requires no fee. Commercial assistance websites may charge for a service you do not need. Check that the address ends in immigration.go.th before entering passport data.
Which is the official TDAC website for Thailand?
The official address is tdac.immigration.go.th. Open it directly or through an official immigration or government source; avoid search advertisements and lookalike domains that ask for payment.
Do children need a Thailand arrival card?
Yes. The official FAQ states that infants and children need a TDAC. A parent or authorised person can submit for them, and the group flow supports up to ten travellers in one submission.
Do I need to fill TDAC for transit in Thailand?
Not if you remain airside and do not pass Thai immigration. If you leave the transit area, collect baggage landside or otherwise enter Thailand through immigration, submit a TDAC before that entry.
Can you edit TDAC after submission?
Use Update Arrival Card before travel for fields the system permits. If the detail cannot be changed, the official FAQ recommends submitting a new correct form; the most recent valid submission is used.
Do I need to print my TDAC for Thailand?
Printing is not required according to the official FAQ. Download the document and QR code to your phone. An optional paper copy can be a useful fallback if your device is unavailable.
What does "within 3 days before arrival" mean?
The official FAQ counts the day you arrive. For example, an arrival on 10 August produces a practical submission window of 8, 9 and 10 August. Use your local Thai arrival date rather than the date you leave home.
