The Thailand Digital Arrival Card (TDAC) is an electronic arrival card that has replaced the old TM6 paper form as of May 1, 2025. Every person entering Thailand—regardless of nationality or purpose of stay—must register their information online via the official TDAC portal. Registration is free and can be completed no earlier than three days before the planned arrival.

Who needs the TDAC?

The Thailand Digital Arrival Card applies to all international travelers entering the country by air, sea, or via a land border crossing. This includes both visa-exempt visitors and holders of a tourist visa, an e-visa, or a non-immigrant visa. Anyone traveling without a completed TDAC risks delays or being denied entry at the border.

TDAC, TM6, and Visa — What’s the Difference?

Many travelers confuse the TDAC with a visa. These are three different documents: The visa (or visa exemption) is what actually grants you entry. The TDAC is simply an electronic registration of your travel details—it replaces the old paper TM6 form but is not a substitute for a visa. For example, if you plan to stay in Thailand for more than 60 days, you’ll need an appropriate visa in addition to the TDAC.

Step-by-Step: Filling Out the Thailand Digital Arrival Card

1. Visit the official TDAC portal no earlier than 72 hours before arrival.
2. Enter your personal information, passport details, and flight number.
3. Provide your address in Thailand (the hotel name and address are sufficient).
4. Review your information and submit it—a confirmation will appear immediately on the screen.
5. Save the TDAC confirmation as a PDF or download it via email—you’ll need to present it upon arrival.

Common Issues with TDAC Registration

In the first few months after the introduction of the Thailand Digital Arrival Card, there were server outages and error messages on the official portal. Common issues include a passport photo in the wrong format, a form filled out too early (more than 72 hours before arrival), or invalid address information. We check your information before submission and ensure the TDAC is submitted correctly—saving you time at the airport.

How much does the TDAC cost?

The Thailand Digital Arrival Card is free on the official portal. Third-party providers that charge fees for TDAC registration are not official and are expressly not recommended. Our visa specialists at buch-dein-visum.de can handle the entire process for you upon request—for a fixed service fee, including data verification and a confirmation backup.

Apply for the TDAC and Visa Together

If you also need an e-visa or a regular visa for Thailand for your trip, we’ll handle both steps for you. This ensures that all your entry documents are properly prepared before you check in at the airport.

Frequently Asked Questions About the TDAC

When does the TDAC become mandatory?

As of May 1, 2025, the Thailand Digital Arrival Card is mandatory for all international travelers. The old TM6 paper card is no longer accepted.

How early can I fill out the TDAC?

No earlier than 72 hours before your scheduled arrival in Thailand. If you fill it out too early, you’ll receive an error message.

What happens if I forget to fill out the TDAC?

Without a completed TDAC, you will not be able to complete the entry process at the Thai border. It is possible to fill out the form at the arrival airport, but this often results in longer wait times.

Do I need a new TDAC for each entry?

Yes—the digital entry card is valid for a single entry only. A new TDAC is required for each subsequent entry (even after a brief departure from Thailand).

Does the TDAC also apply to children?

Yes, every person—including children and infants—needs their own Thailand Digital Arrival Card. Parents can submit their children’s cards together with their own TDAC in the same process.

Where can I find the official TDAC portal?

The official portal is operated by the Thai Immigration Bureau. For security reasons, we do not provide a direct link to it—please contact our team if you need assistance with registration, and we will complete the process on your behalf.
