Travelling to Thailand? The Thailand Digital Arrival Card (TDAC) is an online arrival form that replaces the paper arrival card. The Immigration Bureau guide says non-Thai nationals entering Thailand must submit it online, subject to the exceptions listed in the guide.
Submit within three days before arrival, including the arrival date. Have your passport, journey and accommodation details ready. The official guide also lists health-declaration information among the details requested. Check the guide for your journey type before submitting.
Use tdac.immigration.go.th. The official portal says the form is free. Avoid lookalike websites or services charging to submit it. Save your confirmation and QR code, and check your details before departure. The guide explains which information can be updated.
TDAC is an arrival card, not a visa. Check visa eligibility and passport requirements separately. Entry rules and portal instructions can change, so return to the official sources shortly before you travel.
