Planning a trip to the Land of Smiles? Before you pack your bags, there is one critical step you cannot miss: the Thailand Digital Arrival Card (TDAC).
Since May 2025, Thailand has replaced the traditional paper TM6 immigration form with a fully digital system. Whether you are visiting for a week-long beach holiday or a long-term business stay, understanding the TDAC is essential for a smooth entry.
This guide covers everything you need to know about the TDAC in 2026, including who needs it, how to apply for free, and common mistakes to avoid.
What is the Thailand Digital Arrival Card (TDAC)?
The Thailand Digital Arrival Card (TDAC) is an online pre-arrival registration system managed by the Royal Thai Immigration Bureau. It collects essential traveler information, such as passport details, flight numbers, and accommodation addresses, before you land in Thailand.
Why Was It Introduced?
- Speed: Reduces queue times at immigration counters by pre-processing data.
- Efficiency: Eliminates the need for pen-and-paper forms on the plane.
- Security: Allows authorities to screen travelers more effectively before arrival.
Important Note: The TDAC is NOT a visa. It does not grant you permission to enter Thailand. You must still hold a valid visa or qualify for visa exemption. The TDAC is simply a digital declaration of your arrival.
Who Must Apply for the TDAC?
As of August 2026, the TDAC is mandatory for almost all foreign nationals entering Thailand.
You MUST apply if:
- You are a tourist (visa-exempt or visa-on-arrival).
- You hold a business, education, or retirement visa.
- You are entering via air, land, or sea borders.
- You are traveling with family (each individual needs their own TDAC, though parents can apply for minors).
You are EXEMPT if:
- You are a Thai citizen.
- You are holding a Border Pass.
- You are in transit and do not pass through immigration control (e.g., staying in the international transit area).
When Should You Apply?
Timing is crucial. The system is designed to process data before you arrive.
- Earliest Application: 72 hours (3 days) before your scheduled arrival.
- Latest Application: Technically, you can apply upon arrival, but this may cause significant delays at immigration.
- Recommendation: Apply 2–3 days before your flight to ensure you receive your confirmation email without stress.
Pro Tip: If you have a connecting flight, use the arrival date of your final destination in Thailand as your “Arrival Date.”
How Much Does the TDAC Cost?
The Thailand Digital Arrival Card is 100% FREE.
There are no government fees for submitting the TDAC. Be cautious of third-party websites that charge a “service fee” to fill out the form for you. While these services exist, they are unnecessary. The official government portal is free, easy to use, and available in multiple languages.
Step-by-Step: How to Apply for TDAC
Follow these simple steps to complete your registration.
Step 1: Gather Your Documents
Before starting, have the following ready:
- Valid Passport (with at least 6 months validity).
- Flight Details (Flight number, airline, arrival time).
- Accommodation Address in Thailand (Hotel name, address, phone number).
- Email Address (to receive confirmation).
Step 2: Visit the Official Portal
Go to the official Thailand Immigration Bureau website: tdac.immigration.go.th
Trust Check: Always ensure the URL ends in .go.th. This indicates an official Thai government website.
Step 3: Fill in the Form
Enter your personal details exactly as they appear on your passport. Key sections include:
- Personal Information: Name, DOB, Nationality.
- Travel Information: Flight number, purpose of visit.
- Accommodation: Full address of your first night’s stay.
- Health Declaration: Questions about recent travel history and symptoms.
Step 4: Submit & Save Confirmation
Once submitted, you will receive a QR Code and a reference number via email.
- Save this email.
- Take a screenshot of the QR code.
- You do not need to print it. Showing it on your smartphone is sufficient.
At Immigration: What to Expect
When you land in Thailand:
- Proceed to the immigration counter.
- Have your Passport and TDAC QR Code ready.
- The officer may scan your QR code or ask to see it visually.
- Once verified, you will receive your entry stamp.
Note: Keep your TDAC confirmation until you leave Thailand. In rare cases, officers may ask to see it upon departure.
Frequently Asked Questions (FAQ)
Can I apply for my whole family at once?
Yes. The official portal allows you to add additional travelers under one main application. This is ideal for families or groups.
What if I make a mistake in my application?
Minor typos (like a wrong hotel phone number) are usually acceptable. However, if your passport number or name is incorrect, you should submit a new application. Always double-check your data before hitting submit.
Do I need TDAC for every entry?
Yes. If you leave Thailand and re-enter (e.g., a side trip to Laos or Cambodia), you must complete a new TDAC for each re-entry.
Is the TDAC required for land borders?
Yes. Whether you enter via Suvarnabhumi Airport or cross the border from Malaysia by bus, the TDAC is mandatory.
