Fake TDAC websites: how to spot one, and what to do if you paid

Checked 5 November 2026 by Darius Cheung. Independent guide, not a government website.

Short answer

The official TDAC is free and lives at tdac.immigration.go.th. Any other address, or any request for a card payment to submit the form, means you aren't on the official site. If you paid one, you may not have a valid card: file again on the official site, ask your bank about the charge, and watch out for messages using the details you gave them.

How common is this?

Thai immigration police warned about fake TDAC sites on the day the system launched, 1 May 2025, and said they look official, charge fees and collect sensitive data. In June 2025, immigration, the Tourist Police and embassies ran a campaign urging travellers to use only the official address, attributing part of the problem to scammers manipulating search results.

One account in The Thaiger describes a family of three who paid US$120 each for an "urgent service" and waited hours with no card. Note that article's content comes from a company selling related services, so treat it as one side's story.

Being independent ourselves, we should say this plainly: this site isn't a government site either. We don't file cards, we don't take payment, and we don't see your data. The form you fill in with our extension is still the official one, on the official address.

If you paid or typed your details into a copy

  1. Assume you don't have a valid card. Go to the official site and file. It's free. If you have a card from the other site, compare it, but don't rely on it.
  2. Call your bank about the charge and ask what they can do. Have the date, amount and site address ready, and take screenshots if the page is still up.
  3. Treat your passport details as exposed. Expect convincing emails. Don't open links in messages about your "application", and don't give more details to anyone who contacts you.
  4. Check what's stored. If you created an account with a password you use elsewhere, change it there.
  5. Report it. Thailand's Tourist Police took part in the 2025 campaign, so they are a sensible place to report it.

Are all third-party services scams?

No. An agent can legitimately help a traveller who needs it, and some sell related services openly. The line we'd use: anyone charging for the free 72-hour submission should tell you clearly that it's free on the official site. Many don't. You can do it yourself in a few minutes, and if you're stuck, the step-by-step guide and error guide are free too.

Questions people ask

Is there a TDAC app I should use?

The embassy's instructions point to the website and its QR code. Be careful with apps from search results, and check who publishes them.

Is tdac.immigration.go.th safe?

That's the address the Thai embassy gives. As ever, check the spelling carefully, since copies often differ by a word.

Is ArrivalFiller an official service?

No. It's an independent, free browser extension that fills the official form from answers saved in your own browser. You still submit on the government's site.

ArrivalFiller only runs on the official address. It has no payment step and nothing goes to us, and it won't activate on a copy of the form.

Where this comes from

Rules change, so check the official site before you travel. Where we quote a form's message, we copied it from the form's own public code. Some messages may rarely appear, and we don't run test submissions on government forms.
