Thailand has replaced the paper TM6 form with the Thailand Digital Arrival Card (TDAC), an online arrival form for non-Thai nationals entering the country.
Complete it within the three days before arrival, including the arrival date. Have your travel and accommodation details ready and keep the confirmation accessible for your journey.
The card is separate from the border itself. Who can use Thailand’s automated passport channels today sets out what the airports publish about meeting an officer or a machine on arrival. Neither channel excuses you from this form.
What the card is
TDAC collects travel, accommodation and health information before arrival. It is not a visa and does not replace any entry or visa requirement that applies to your passport.
