Thailand Digital Arrival Card (TDAC)

TDAC is Thailand’s mandatory digital arrival card system run by Immigration. Travellers submit identity, trip and accommodation details so officers can process arrivals faster than with paper forms.

Complete it only on the official site: https://tdac.immigration.go.th. Keep a confirmation / QR as instructed by the portal.

• Most non-Thai citizens arriving by air, land or sea under current Immigration rules
• Submit typically within 72 hours before arrival
• Health declaration often unlocks only inside that 72-hour window — submission is incomplete until finished
• Thai nationals generally follow different procedures — this guide is for foreign travellers

1. Go to https://tdac.immigration.go.th (bookmark the official domain).
2. Enter passport and personal details exactly as on the passport.
3. Add flight / arrival details and accommodation in Thailand.
4. Complete the health section when it becomes available in the 72-hour window.
5. Save or screenshot your confirmation / QR code before you travel.

• Spell names exactly like the passport, including middle names.
• Do not use unofficial “helpers” that charge fees.
• If you also use the THIM app, still treat TDAC rules as binding unless Immigration states otherwise.
• Wrong district for accommodation is less critical than a wrong passport name — fix names first.

What is the Thailand Digital Arrival Card (TDAC)?

TDAC is Thailand’s mandatory digital arrival card for most foreign travellers. It replaced the old paper TM6 card and must be completed before arrival within the official time window.

Where do I fill in the TDAC?

Use only the official government portal: https://tdac.immigration.go.th — or follow Immigration guidance for completing arrival details via the official THIM app.

When must I complete the TDAC?

Typically within 72 hours before arrival. The health declaration often unlocks only inside that window — your submission is incomplete until that step is done.

Do I need THIM as well as TDAC?

TDAC is the arrival-card requirement. THIM is the Immigration Bureau’s broader app that can help with digital arrival flows. See ThaiPlot’s THIM guide for the comparison.

Can websites charge for TDAC?

No. Official TDAC is free. Paying a third party for “TDAC processing” is a common scam.

The THIM (Thailand Immigration Management) app is Immigration’s broader mobile platform. It works with digital arrival flows but does not replace TDAC. Read our THIM guide for downloads and comparison.
