Thailand TDAC, the free form, and how to spot the sites pretending to be it.

The Thailand Digital Arrival Card (TDAC) replaced the paper arrival card in May 2025. It is required for every foreign arrival, free to file, and accepted only at tdac.immigration.go.th.

In March 2026, the Royal Thai Immigration Bureau stated that about 10% of foreign arrivals paid a middleman to submit this free form. That is the problem we are trying to fix, one honest page at a time.

The fast facts

• Official URL: tdac.immigration.go.th — nothing else ends in .go.th, and that suffix is restricted to Thai government entities.
• Cost: free. Always free. No premium, fast-track, or priority tier exists.
• When to file: within 3 days before your arrival. Filing earlier gets rejected.
• What you need: passport, flight number, arrival date, email, about 8 minutes.
• What you get: a QR code, by email. Screenshot it. That is what you show at immigration.
• If you already paid a middleman: dispute the charge with your card issuer as “service not rendered” or “deceptive practice.” Success rates are highest within 60 days.

Who we are, who we are not

We are not the Royal Thai Immigration Bureau. We are not a travel agency. We do not file your TDAC for you, and we would not take your money if you asked us to.

Our current affiliate revenue comes from clearly disclosed travel affiliate links (travel insurance, eSIM, airport transfers) in eligible guides. We have never taken money from a visa middleman, and we will not. Read more on our about page.
