Understanding the TDAC System
Thailand has officially replaced the old paper-based TM6 arrival and departure card with a fully digital system known as the Thailand Digital Arrival Card, or TDAC. Launched in May 2025, this system is now a mandatory requirement for all non-Thai travellers
entering the country, regardless of their visa status or mode of entry—whether by air, land, or sea. The primary goal of the TDAC is to streamline the immigration process, reduce wait times, and enhance security by integrating arrival data into a unified biometrics system. It's crucial to understand that the TDAC is not a visa; it is a compulsory declaration of your identity, travel details, and accommodation. Completing it is free of charge on the official government portal.
When and Where to Fill Your Form
Timing is key when it comes to the TDAC. You can only submit the form within a specific window: no earlier than 72 hours (3 days) before your scheduled arrival in Thailand. The system will not allow you to submit your details before this period to ensure all information is current. It is highly recommended to complete the form at least a day or two before you fly to avoid any last-minute stress. You must use the official Thai Immigration website to fill out the form. Be wary of third-party websites that may look similar but charge a fee for this free service. Once submitted, you'll receive a confirmation with a QR code, which is essential for your arrival.
A Step-by-Step Guide to Submission
Navigating the TDAC portal is straightforward if you have all your information ready. First, visit the official TDAC website and select the option for the arrival card. You will need to gather several key documents and details before you begin: your passport, details of your return or onward flight, and the full address of your first night's accommodation in Thailand. The form will ask for personal information (name, date of birth, passport number), travel details (flight number, date of arrival), and your accommodation information. The system is strict about data accuracy, so double-check that the name and passport number you enter match your travel documents exactly to avoid issues at immigration.
Special Information for Indian Travellers
For Indian citizens, Thailand remains a highly accessible destination. As of mid-July 2026, the Thai government confirmed that Indian passport holders will continue to receive visa-free entry. However, the maximum stay under this scheme has been adjusted to 30 days, down from a previous 60-day allowance. This change does not affect the majority of tourists. Alongside your visa-free entry, completing the TDAC is still mandatory. Ensure you carry confirmations of your return ticket and hotel bookings, as immigration officials may ask to see these. While there were some confusing reports earlier in the year, the 30-day visa-free arrangement is the current and confirmed policy.
After You Submit: The QR Code
After you have filled in all the details and reviewed them for accuracy, you will enter your email address and submit the form. You should then receive a confirmation, typically as a downloadable PDF file containing a unique QR code. It is vital to save this file to your phone and also consider keeping a printed copy as a backup. This QR code is your digital pass through immigration. Upon arrival at the airport in Thailand, you will need to present this QR code along with your passport to the immigration officer. The officer will scan the code, which pulls up your pre-submitted information, making the entry process significantly faster and smoother than the old paper system.
Common Pitfalls to Avoid
The most common mistake travellers make is using unofficial websites that charge for the TDAC submission. Remember, the official process is completely free. Another frequent error is making typos in crucial information like your passport number or name; even a small mistake can lead to delays. Always double-check every field before submitting. Finally, don't wait until the last minute at the airport to fill out the form, as you might face issues with internet connectivity. Completing it a day in advance ensures a stress-free start to your holiday. By being prepared, you can ensure your arrival in the Land of Smiles is as pleasant and welcoming as the country itself.
