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.
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.
Follow the official link, submit only inside the permitted three-day window, check every field, and retain the confirmation for your journey.
This page is a preparation guide. Thai Immigration’s TDAC website remains the source of record.
Go directly to tdac.immigration.go.th; do not begin from an advertisement or an unofficial payment page.
Complete the form during the official submission window, using the arrival and accommodation details for this trip.
Keep the confirmation accessible and return to the official system if you need to review the submitted record.
Treat this as the traveler prep layer, not the official source itself.
| Step | What to prepare | Why it matters |
|---|---|---|
| Before the window opens. | What to prepare: Passport, travel, first-accommodation, and contact details | Why it matters: You can prepare without submitting too early |
| Within three days of arrival. | What to prepare: Use only the official Thai Immigration TDAC website | Why it matters: The official submission is free and avoids look-alike payment sites |
| After submission. | What to prepare: Save the confirmation and keep it accessible during travel | Why it matters: You can reopen the record instead of relying on memory or a search result |
| If details or rules are uncertain. | What to prepare: Return to the official instructions and system | Why it matters: Current government instructions outrank old posts and third-party summaries |
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.
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.
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.
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.
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.
This guide is stronger when you can see which quarter or audience made the topic more important. Use the linked research pages for that wider context.
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.
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.
Check the official TDAC instructions again before travel because entry procedures can change. Avoid third-party sites that imply a government fee is required.
Start with the government form, then use practical safety and travel pages only for separate trip questions.
Do not submit a second record or pay an intermediary merely because something looks wrong. Start from the official system and match the next step to the problem you actually have.
Return to the official TDAC system and follow its current update instructions. Recheck passport, arrival, and accommodation details before saving.
