Thailand Digital Arrival Card (TDAC): Official, Free Entry Steps

Use the official Thai Immigration form at tdac.immigration.go.th. Submission is free and should be completed within the three days before arrival in Thailand.

Decision

Use the official free TDAC form within the three days before arrival.

Prepare your passport, travel, accommodation, and contact details; submit through Thai Immigration; then save the confirmation where you can reopen it during travel.

What TDAC changes

TDAC is the digital pre-arrival form for foreign nationals entering Thailand by air, land, or sea. It does not replace a passport, visa, or any separate entry requirement.

What travelers usually get wrong

The official form is free. A commercial or look-alike website may charge for assistance, but that fee is not the Thai government’s TDAC submission fee.

How to use this page

Follow the official link, submit only inside the permitted three-day window, check every field, and retain the confirmation for your journey.

The TDAC workflow in three steps

This page is a preparation guide. Thai Immigration’s TDAC website remains the source of record.

Step 1 Open the official free form

Go directly to tdac.immigration.go.th; do not begin from an advertisement or an unofficial payment page.

Step 2 Submit within three days of arrival

Complete the form during the official submission window, using the arrival and accommodation details for this trip.

Step 3 Save and recheck the confirmation

Keep the confirmation accessible and return to the official system if you need to review the submitted record.

TDAC preparation checklist

Treat this as the traveler prep layer, not the official source itself.

Why TDAC became a core topic

TDAC is not generic paperwork. It became one of the clearest traveler-intent topics because it changed the entry workflow for foreigners and stayed relevant after launch rather than fading into a one-week news spike.

What belongs on the page

Keep four layers separate: official source of record, the traveler checklist, scam and confusion warnings, and the editorial trip implication if the process is delayed or misunderstood.

What not to overclaim

Do not present third-party agents, old arrival-card habits, or social chatter as if they were the official process. If the operational detail is uncertain, say so and send the reader back to the official path.

How it changes trip planning

A clean first day depends on finishing TDAC on time, carrying the right confirmation, and not letting an avoidable entry issue become the story of the arrival day.

Keep TDAC separate from itinerary planning

The same national arrival process applies regardless of whether the trip begins in Bangkok, Chiang Mai, Phuket, or another destination. Weather, routes, and regional pivots belong in destination guides—not inside the entry-form instructions.

Complete TDAC through the official flow, do it on time, keep the confirmation easy to show, and do not rely on random third-party explainers.

What should I do first?

Open the official TDAC website at tdac.immigration.go.th. The government form is free; submit it within the three days before you arrive in Thailand.

If an unofficial site asks for payment or the instructions conflict, stop and return to the official Thai Immigration TDAC website.

What should I check before using this guide?

Check the official TDAC instructions again before travel because entry procedures can change. Avoid third-party sites that imply a government fee is required.

After submission: use the official route for the exact problem
