Thailand Digital Arrival Card (TDAC)

Free online arrival card for all foreign nationals; replaces the paper TM6.

Only use the official site. Lookalike sites copy official forms and charge for them. In March 2026, Thailand's Immigration Bureau told reporters that at least 1 in 10 foreign arrivals had used a fake TDAC site (press reports: Bangkok Post, Khaosod English, 29 March 2026). Check the address before you type anything: it should be tdac.immigration.go.th.

Before you open it

Have your passport and your travel plans to hand, then answer the questions on the official site itself. We don't reproduce the form here: the official version is the only one that counts, and it can change without notice.

Get it right first time

TripEase tells you whether your passport needs TDAC, reminds you when it opens for your trip, and gives you one-tap access to the official form, with your details ready to copy. You always submit on the official site yourself.
