Thailand’s Digital Arrival Card (TDAC)
The Thailand Digital Arrival Card (TDAC) has been required since 1 May 2025. This new online form replaces the traditional paper-based TM6 arrival cards previously required for all non-Thai travelers. The TDAC is mandatory for entry by air, land, or sea and aims to streamline the immigration process.
Rules checked: 3 September 2026. The process below follows Immigration's current TDAC guide, version 1.18 for application version 2026.08.00.
We’ve not had to fill out the TM6 form since 2022, which has been great, so we’re not sure this is streamlining or improving anything from the travelers perspective.
If you don’t hold a Thai passport you must complete the TDAC before entering Thailand. The current exceptions include travellers in international transit who do not pass through immigration and crew. If you will clear immigration, collect bags or make a self-transfer, submit one.
Remember: The TDAC isn’t a visa or visa substitute; you must still ensure you have the correct visa or qualify for visa exemption for your trip.
Read our visa exemption and Visa on Arrival guide or use the Thailand visa finder if you are unsure.
Applying for the TDAC is quite straightforward. You can submit your application online up to three days before your arrival date. Technically, you could complete it upon arrival in Thailand, but we recommend applying beforehand to speed up immigration. Immigration's current FAQ says kiosks and Wi-Fi are available at five named airports; that is a fallback, not a reason to leave the form until landing.
The official application is available at https://tdac.immigration.go.th, and you can complete it using a phone, tablet, or computer (the airport wifi has been hit and miss in the past).
After submitting your TDAC application, you’ll receive a QR code via email. Keep this QR code handy, as you’ll need to show it (on your phone or printed) with your passport at immigration.
Here’s the process:
- Go to the official website: https://tdac.immigration.go.th
- Click “Arrival Card” and enter required information. Everything must be in English.
- Provide information about your travel plans, including your initial accommodation.
- List countries visited within two weeks prior to your arrival (required for health declarations).
- Review your information, correct errors.
- Submit your application and receive your QR code via email.
- Download or print the QR code.
If you make a mistake or your plans have changed, you can update your TDAC details anytime before arrival (note that passport number, nationality, name, and date of birth cannot be changed after submission). Immigration's FAQ says to submit a new correct form for one of those fields, after which the latest valid submission is used.
The system supports group submissions of up to ten travellers, and children need their own entry. If you arrive without internet access, Immigration's current FAQ says kiosks and Wi-Fi are provided at specified airports; do not make that your first choice when the form can be completed before travel.
