Submit within 3 days before your arrival date, including that date. You do not need to submit one if you are only transiting through an airport without going through Thai immigration.

Where do I complete the TDAC, and how much does it cost?

Complete it on the Thai Immigration Bureau’s official website, tdac.immigration.go.th. Official submissions are free, so use the official domain instead of similar sites that charge a fee.

How do I complete the TDAC arrival card?

Have your passport, flight information, address in Thailand, and an email address you can access ready, then enter them on the official website. The form asks for passport details, flight and arrival date, address in Thailand, purpose of travel, health declaration information, and email address.

Do family members and children need separate TDACs?

Every non-Thai traveler, including infants and children, needs their own TDAC. A representative can gather and submit information for family members or a travel group, with up to 10 people included in one submission.

How can I correct information after submitting?

You can correct eligible details using the “Update Arrival Card” feature. You cannot change your name, passport number, nationality, or date of birth this way. If any of these details are wrong, submit a new TDAC with the correct information. If the same person submits more than once, the most recent submission is valid.

What if I complete it after arrival or enter Thailand again?

If you could not submit in advance or cannot access the internet or a smartphone, you can use a TDAC kiosk and Wi-Fi at the arrival airport. The official FAQ lists kiosks at Suvarnabhumi, Don Mueang, Phuket, Chiang Mai, and Hat Yai airports.

A TDAC is valid for one entry on the arrival date shown. Submit a new one every time you re-enter Thailand after leaving.

What to do in these situations

When submitting for your family

Gather each traveler’s information and include up to 10 people in one submission. Children and infants must each have their own details entered.

If there’s an error in your submission

First, check whether the item can be corrected using “Update Arrival Card.” If a key passport detail is wrong, submit a new TDAC with the correct information.
