The End of the Paper Chase
For years, travellers to Thailand were familiar with the paper TM.6 arrival and departure card, often hastily filled out on the plane. As of May 2025, this paper form was officially replaced by the Thailand Digital Arrival Card, or TDAC. This online system
is mandatory for all foreign nationals entering the country, whether by air, land, or sea. The move was designed to streamline the entry process, making it faster, more secure, and entirely paperless. For Indian travellers, this means no more fumbling for pens or trying to balance a form on your lap during final descent. Thai nationals are exempt from this requirement.
Why Filling It Out Early Is a Game-Changer
The single biggest advantage of the TDAC system is the ability to complete it before you even leave for the airport. The official portal allows you to submit your details up to 72 hours (or three days) before your arrival time in Thailand. Completing it early eliminates the last-minute scramble and potential for errors made under pressure. It means that when you land, your information is already in the immigration system. Instead of joining a queue to fill out a form, you can proceed directly to the immigration counter, where the officer can access your details electronically. This simple act of preparation can be the difference between a 20-minute wait and an hour-long ordeal, a common pain point for travellers arriving during peak hours.
A Step-by-Step Guide to the TDAC
Completing the form is free and straightforward, taking only about five minutes if you have your information ready. 1. Visit the Official Website: The only place to complete the form is the official Thai Immigration Bureau portal: tdac.immigration.go.th. Beware of third-party websites that charge a fee; the official service is always free. 2. Gather Your Documents: Before you start, have your passport, flight number, and the full address of your first night's accommodation in Thailand handy. 3. Enter Your Details: The form will ask for personal information exactly as it appears on your passport, followed by your travel details like arrival date and flight number. All information must be entered in English. 4. Complete the Declaration: You may need to answer simple health declaration questions, such as listing countries you have visited in the 14 days prior to your arrival. 5. Review and Submit: Double-check all entered information for accuracy. After submitting, a confirmation with a QR code will be sent to your email. Save a screenshot of this QR code on your phone as a backup.
Common Mistakes to Avoid
To ensure a seamless process, steer clear of these common pitfalls. First, do not use unofficial websites that ask for payment; the TDAC is a free government service. Second, ensure all details, especially your name and passport number, match your passport perfectly to avoid any mismatch in the system. Third, have your hotel address ready. Simply putting "Bangkok" is not enough and can cause delays. Finally, remember the 72-hour submission window. Trying to fill the form a week in advance will not work as the system will not accept it. If you are travelling with family, including infants, remember that every single traveller must have a completed TDAC. You can submit for a group of up to 10 people in one session.
What to Expect at Thai Immigration
Upon arrival, head to the immigration counters designated for foreign passports. While the officer can pull up your details digitally, it is wise to have the QR code confirmation email or screenshot ready on your phone in case you are asked for it. The officer will scan your passport, take your fingerprints and a photo, and stamp your entry into the kingdom. With your TDAC already filed, the process is significantly quicker. You are not required to print the confirmation, showing it on your smart device is sufficient. This streamlined process means you can get to the baggage claim and start your Thai adventure that much faster.
