The Thailand Digital Arrival Card, explained without a fee.
10% of foreign arrivals to Thailand in 2026 paid a scam site to submit a free form. Here is the official site, every field it asks, and how to tell real from fake.
What the TDAC actually is
The TDAC is a free form you fill out before entering Thailand. The Thai government introduced it in May 2024, replacing the paper arrival card. It takes about 8 minutes if you have your passport and flight details in front of you.
No one can charge you for it.
No one can submit it faster than you can.
There is no fast-track, priority, premium, or “white-glove” service. Those services do not exist. The only legal destination for your TDAC form is tdac.immigration.go.th, a domain reserved for Thai government entities under the .go.th suffix.
The problem
If you search Google for “thailand digital arrival card” right now, the first three results are paid ads from middlemen charging $20 to $90 to fill a free form. Some of them submit the real form on your behalf. Some of them don’t, and you find out at immigration.
In March 2026, Thai authorities publicly named iVisa as one of these middleman sites. The Royal Thai Immigration Bureau stated that approximately 10% of foreign arrivals had used unofficial sites and overpaid.
Before you touch any form
Check the address bar. The official site is tdac.immigration.go.th and nothing else.
Not thailand-tdac.com. Not official-tdac.org. Not any variant with gov, official, or immigration in the domain that doesn’t end in .go.th. Anyone can register a .com. Not anyone can register a .go.th.

Every field the official form asks
The TDAC has 23 fields across 4 sections: passport, trip, health, and contact.
None of them require a photo upload.
None of them require payment.
If a site asks for either, you are not on the official site.

Known sites that are NOT the TDAC
These sites all charge money for a free form. Some of them submit a real form on your behalf. Some of them do not.

Frequently asked
Is there a fee for the TDAC?
No. Anyone charging you for the TDAC is a middleman. The Royal Thai Immigration Bureau does not collect any payment for this form.
Can I fill it on my phone?
Yes. The official site is mobile-friendly. We recommend filling it on a laptop if possible because the character limits on some fields are tight and typing with a keyboard reduces errors.
When should I fill it?
Within 3 days before your arrival in Thailand. Earlier than that, the official site will reject the submission.
I already paid a middleman. Can I get a refund?
Contact your credit card issuer and dispute the charge as “service not rendered” (if they didn’t actually file your form) or “deceptive practice” (if they did file but charged a fee for a free service). Success rates vary.
I filled out the form but didn’t get a confirmation email.
Check spam. If still missing after 1 hour, submit again. The official site is idempotent — duplicate submissions are harmless and the most recent one applies.
