The Thailand Digital Arrival Card (TDAC) is a new mandatory online registration system for all non-Thai nationals entering Thailand by air, land, or sea.
It replaces the traditional paper-based TM.6 arrival card and is part of Thailand’s move to digitize and streamline its immigration process [3][4].
Key Features and Requirements
Who Must Complete TDAC:
All foreign nationals (non-Thai passport holders), regardless of visa type or length of stay, must complete the TDAC before entering Thailand. This includes tourists, business travelers, and long-term residents. Thai nationals are exempt[3][4][5][6].
When Should You Fill It Out?
The TDAC must be submitted online within three days (72 hours) prior to your scheduled arrival date in Thailand. The system opens for submissions three days before your arrival, and you can also complete it at the airport, if necessary, though advance completion is strongly recommended to avoid delays [1][3][4][6][7].
What happens if I start filling it out before the three-day window?
If you begin filling out the Thailand Digital Arrival Card (TDAC) before the three-day (72-hour) window prior to your scheduled arrival, the system will not allow you to submit the form.
The process is designed so that registration and submission are only possible within the allowed three-day window.
Most sources recommend preparing your information in advance but waiting until the three-day window opens to actually start and submit your TDAC.
If you attempt to submit before the window, you will likely need to start over when the system allows submissions, as there is no indication that the portal saves early, incomplete entries for later retrieval.
What Do I have to Do?
Registration is done through the official portal at
tdac.immigration.go.th. The process involves entering personal details, passport information, travel itinerary, accommodation in Thailand, and a health declaration
[3][4][5][6][7].
What if I'm Travelling in a group or with my family?
Families or groups can submit their TDAC registrations together in a single session, but each traveler must have their own individual TDAC confirmation [3][5].
What languages are available?
The system is available in English, Chinese, Korean, Russian, and Japanese [5][6].
How do I know that my information has been accepted?
After submission, travelers receive an electronic confirmation (usually by email), which must be presented-either digitally or as a printout-along with travel documents to immigration officers upon arrival [5][6][7].
How much does it cost?
There is no charge to complete the TDAC registration [5].
What Information Is Required?
- Passport details and personal information
- Travel details (flight/vehicle number, date of arrival)
- Address of accommodation in Thailand
- Health declaration (including recent travel history and, if relevant, proof of vaccination for diseases like Yellow Fever) [4][5]
Important Notes
TDAC is Not a Visa:
The TDAC is not a visa and does not replace any visa requirements. Travelers must still obtain a visa if required for their nationality or travel purpose [4][5][6].
Health and Security:
The TDAC includes a health declaration to help Thai authorities monitor and prevent the spread of communicable diseases and to enhance border security [4][5].
If you are arriving from, or have recently transited through, a country with a risk of yellow fever transmission (primarily in Africa and Central/South America), you must present a valid yellow fever vaccination certificate upon entry to Thailand.
Even if you only had a layover of more than 12 hours in a yellow fever country, the requirement still applies.
Failure to Comply:
Not completing the TDAC in advance may result in delays, denial of entry, or other immigration-related issues.
Assistance is available at immigration checkpoints for those unable to complete the form online, but this is intended for exceptional cases only [3][6].
