Planning a trip to Thailand from India in 2026? Thailand is one of the most visited countries in the world and for good reason. Beautiful beaches, amazing street food, rich temples, and a nightlife scene that is hard to match anywhere else.

But before you board your flight, there is one new step every Indian traveller needs to know about. It is called the Thailand TDAC form, short for Thailand Digital Arrival Card. It replaced the old paper TM6 arrival card that travellers used to fill out on the plane. This guide covers everything about the TDAC: who needs it, how to fill it out, and what happens if you skip it.

What Is the Thailand Digital Arrival Card?

The Thailand Digital Arrival Card, or TDAC, is an online registration form that all international travellers must complete before arriving in Thailand. Think of it as a digital version of the paper arrival card you used to fill out mid-flight.

But the TDAC is smarter, faster, and fully online. You fill it out before you travel. Once submitted, you receive a QR code by email. You show that QR code at immigration when you land in Thailand. The Thai government made this mandatory to speed up the arrival process at airports and to keep better records of who is entering the country. For a complete overview of entry requirements, documents, and the latest regulations, check out our guide on Thailand Travel Rules for Indians 2026.

Do Indians Need to Fill the Thailand TDAC Form?

Yes, all Indian passport holders travelling to Thailand must complete the Thailand TDAC form before arrival, whether you are visiting for tourism, a family trip, honeymoon, or transit. There are no exceptions based on nationality. Every international traveller arriving in Thailand by air must register through the TDAC system. Also, the Thailand TDAC form is completely free to fill out. There is no government fee for TDAC registration. 

For more information and regular updates, you can refer to the official website of Thailand Visa.

Common Mistakes Indians Make When Filling the Thailand TDAC

Some of the common mistakes Indians make when filling the TMAC:

• Entering details that don’t match the passport. Even a small spelling difference can cause issues.
• Filling it too early. The TDAC window is typically 72 hours before arrival. Filling it a week in advance may not be accepted.
• Not saving the QR code. Some travellers fill the TDAC but forget to save or screenshot the QR code. Without this, you will need to log back in at the airport, which wastes time.
• Entering the wrong hotel address.

Thailand Visa and TDAC: What Is the Difference?

Many Indian travellers confuse the TDAC with the Thailand visa. They are two completely different things.

• Thailand Visa: It allows travellers to enter the country, but not everybody needs to apply for it, as it depends on the nationality. Indian travellers can currently take advantage of the Thailand Visa on Arrival for Indians facility, subject to the latest government regulations.
• Thailand TDAC Form: The TDAC form is a digital arrival registration that every international traveller needs to apply before even flying atleast 24 to 72 hours before entering the country. It registers you and makes the immigration process very easy. 

You need both. Your visa gets you permission to enter. Your TDAC registers your arrival digitally. But as for Indian nationals, they just need to fill out the form; no need for a visa, as they have a visa-on-arrival option.

Conclusion

The Thailand TDAC form for Indians is a simple, free, and mandatory step before every trip to Thailand in 2026. It takes less than 10 minutes to complete, and it makes your airport arrival smoother and faster. Fill it out 24 to 72 hours before your flight, save your QR code, and you are good to go.
