Thailand Digital Arrival Card (TDAC)

The Thailand Digital Arrival Card (TDAC) is an online form that replaced the old TM6 paper arrival card, effective May 1, 2025, to streamline immigration and enhance border security. It is mandatory for **all foreign nationals** entering Thailand by land, air, or sea, regardless of their visa status or type (including those entering visa-free or with long-term visas). Thai citizens are exempt.

You can submit the TDAC form **no earlier than 3 days (72 hours) prior to your arrival** in Thailand. If you attempt to submit it earlier than this 3-day window, the system will reject your arrival date, often showing an 'invalid format' error. You can submit it anytime within the 72-hour window, including upon arrival at the airport before passing through immigration.

The official Thailand Digital Arrival Card is **completely free to complete**. If you are asked for credit card information or charged a fee, you are likely on a third-party or scam website. Thai Immigration police have repeatedly warned travelers to use only the official TDAC website to avoid these scams. The official government website uses the `.go.th` domain.

No, you do not need to complete the TDAC if you are a transit passenger and **do not pass through Thai immigration** (i.e., you stay within the international transit area). However, if your transit requires you to pass immigration to retrieve luggage, change terminals, or check in for an onward flight, then you must complete the TDAC.

The TDAC requires personal details, travel itinerary, and accommodation information. All details must be entered in **English (Latin alphabet)**, avoiding non-Latin characters like Arabic, Cyrillic, or French accents. Key details include your passport number, full name, date of birth, occupation, and the flight number of the plane that lands in Thailand. For accommodation, only the address of your **first place of stay** in Thailand is required. You may also be required to provide a health declaration and proof of Yellow Fever vaccination if traveling from an at-risk country.

Yes, you can update most information after submission, such as travel and accommodation details, before your trip. However, certain **personal identity information cannot be updated** once submitted, including your full name (as in your passport), nationality/citizenship, and date of birth. If you make a mistake in these specific fields, you must submit an entirely new TDAC registration.

Yes, you must register for the TDAC for **every entry** into Thailand. The TDAC is only valid for the specific entry you declare.

After submitting the form online, you will receive an electronic confirmation, usually immediately, via email. Although your TDAC is recorded in the immigration system once submitted, it is recommended to **save a screenshot of the QR code** or print a paper copy to present to the border officer upon arrival, just in case they request it.
