Thailand has moved from the paper TM6 form to the Thailand Digital Arrival Card, or TDAC. It is an online arrival form for non-Thai nationals entering the country.
Complete the form within the three days before arrival, including the arrival date. Have your travel and accommodation details ready, then keep the confirmation accessible for your journey.
What is the Thailand Digital Arrival Card?
TDAC collects travel, accommodation, and health information before arrival. It is not a visa and does not replace any separate entry or visa requirement that applies to your passport.
