About the Thailand Digital Arrival Card

The electronic Thailand arrival card (Thailand Digital Arrival Card) is shortened to TDAC. It lets visitors submit required trip details before they reach Thailand, including the flight, accommodation, and passport, so the Thai government can keep track of arrivals.

Whether or not you need a visa,every foreign national must complete it online. Paper arrival cards are not handed out on the plane.

When did the TDAC start?

The measure has been in effect since May 1, 2025, and every foreign visitor entering Thailand must complete it. There is no exception.

Where do you fill in the TDAC?

The official site for the Thailand Digital Arrival Card is https://tdac.immigration.go.th. If you see a different address, treat it as a scam site and keep your personal data off it.

Does the TDAC cost anything?

The Thailand arrival card iscompletely free. Any site that asks you to pay during the application is a scam. Watch for that.

Still need data for the trip?An eSIM does not need to be mailed. Set it up on the phone and you are online, with no card swap. Match the days and data yourself. Buying at the last moment before boarding still works.

What you need for the arrival card

Before you fill in the Thailand Digital Arrival Card, have these ready:

• Personal details: name, nationality, date of birth, and similar items
• Passport details: the biodata page. The passport must still have more than 6 months of validity before you enter Thailand.
• Flight details: flight numbers and dates for arrival in Thailand and departure from Thailand.
• Accommodation details: the name and address of the hotel or place you are staying.

Next, enter the date you arrive in Thailand, where you are coming from, the purpose of the trip, the flight number, and similar details. For mode of transport, choose COMMERCIAL FLIGHT.

The address also asks for the province, district, and subdistrict. The example below uses one hotel address to show how to split them.
