Planning a trip to Thailand in 2026? Before packing your bags, make sure you complete the Thailand Digital Arrival Card (TDAC). The TDAC is an online arrival form that replaces the traditional paper arrival card and helps Thai immigration process travelers more efficiently.

Whether you’re visiting Thailand for a vacation, business trip, or family visit, this guide explains who needs the TDAC, how to apply, the required documents, and common mistakes to avoid.

What Is the Thailand Digital Arrival Card (TDAC)?

The Thailand Digital Arrival Card (TDAC) is an online immigration form that international travelers must submit before arriving in Thailand.

Instead of filling out a paper arrival card on the plane or at immigration, travelers can now submit their travel information online, making the arrival process faster and more convenient.

The TDAC is not a visa. It is simply an arrival registration required by Thai immigration authorities.

Who Needs to Complete the TDAC?

Most foreign travelers entering Thailand are required to complete the TDAC before arrival, including:

Tourists
Business travelers
Students
Visitors meeting family or friends
Visa holders
Visa-exempt travelers

Thai citizens generally do not need to complete the TDAC.

When Should You Apply?

It is recommended to submit your TDAC within the permitted submission window before your arrival (as specified by Thai authorities).

Avoid waiting until the last minute to prevent delays caused by internet issues or incorrect information.
