You are not alone if you are unsure whether to fill out a TDAC or a TM6 if you are traveling to Thailand soon. Recent immigration updates have left many travelers seeking clarity. Is it necessary to have both? Just one? Which one applies to air travel, and which one to land travel?
Learn what TDAC vs TM6 are, who needs them in 2025, and how to avoid travel hiccups at immigration with this guide. No matter who you are-a solo tourist, a business traveler, or a family visiting-you’ll find clear, up-to-date info tailored to real travel scenarios.
Getting to know TDAC
In order to replace manual entry forms for air passengers, Thai immigration has introduced the Thailand Digital Arrival Card (TDAC). Travelers can submit their entry details online before arriving, reducing immigration wait times.
TDAC Key Facts:
- Almost all non-Thai air travelers require it
- It must be filled out online before your flight
- A physical TM6 card is no longer required at airports
- The purpose of this form is to collect information such as passport details, travel plans, and accommodation information
You will be processed faster upon arrival if you complete TDAC before departure. Additionally, it reduces paperwork errors caused by handwritten TM6 cards.
TM6 – Traditional Arrival/Departure Cards
A TM6 card is a physical paper card that was previously handed out on flights or at immigration. For years, it was the standard form of entry and exit into Thailand.
Highlights of TM6:
- Information about arrivals and departures
- All travelers were required to wear it (before digital systems)
- For air travelers, currently suspended
- Some land or sea borders still use it
TM6 forms have faded from airports, but they haven’t disappeared completely. If you enter Thailand via a land crossing from a neighboring country like Laos or Malaysia, you might still be asked for it.
