Planning to travel to Thailand in 2025? Before packing your bags, here’s an important update every traveler should know: Thailand has officially launched the Thailand Digital Arrival Card (TDAC), an online platform that replaces the traditional paper declaration. No more fumbling with forms on the plane or queuing at the airport to complete the procedure – now, just a few minutes of declaring online is all it takes to enter the country quickly!
Our detailed guide will help you understand what TDAC is, how it differs from the old paper system, the step-by-step process for completing your online immigration declaration, and helpful tips before your trip. Whether you are a first-time visitor or returning to Thailand, this article will ensure your trip goes smoothly.
What is TDAC?
If you have been to Thailand, you are probably familiar with the TM6 immigration form, also known as the Thai Immigration Department’s Arrival and Departure Card, which is a mandatory document for foreign visitors entering Thailand. Previously, visitors would receive the form on the plane or at the border and had to fill it out and submit it to the immigration officer. However, from May 1st 2025, Thailand will implement an online declaration system through the Thailand Digital Arrival Card (TDAC), completely replacing the traditional paper application form for a smoother entry process.
TDAC is a new online declaration system, replacing TM6
The Thailand Digital Arrival Card is an online application developed to replace the paper immigration form, integrating with Thailand’s e-visa, health screening and tourist fee collection systems. It is designed to facilitate all foreigners entering Thailand by air, land or sea.
How is TDAC different from the previous process?
The TDAC has the same content as the previous TM6 paper declaration, except that visitors can complete it online. Specifically, the online declaration form is divided into several sections, including personal information, travel itinerary and accommodation details, health declaration, and finally signature confirmation.
The previous TM6 paper declaration
Visitors need to complete the declaration form online at the official website of the Thai Immigration Department within 3 days before arriving in Thailand. After submitting the application, a digital card will be sent via email. Visitors must print or save it on their smartphone to present at the immigration office. When entering the country, officers will scan the QR code to check the information, helping to shorten the processing time compared to filling out the previous paper declaration form.

Important notes and preparation tips before traveling to Thailand after the change
The move to the online TDAC system may be a little daunting for some travelers at first, but it’s actually an improvement that makes the immigration process much faster and more convenient. So how can you make sure your trip goes smoothly? Here are some important things to remember before you leave:
1. Complete the TDAC Declaration Form before you fly
This process only takes a few minutes but will save you dozens of minutes of queuing when you arrive. We recommend you declare at least 3 days in advance to ensure there are no last-minute issues.
2. Save your QR code
After completing the declaration, the system will send a QR code to your email for you to present at immigration, so save it on your phone or print it out in case your phone runs out of battery or has network problems. Don’t forget to double-check the code before you arrive to avoid any unwanted situations.
3. Prepare all necessary documents
Please note that the Thailand Digital Arrival Card is not a visa. You must still ensure that you have the appropriate visa or visa exemption to enter Thailand. Some important documents include:
- Passport valid for at least 6 months.
- Return or onward air ticket (if not a Thai citizen).
- Confirmed hotel reservation or address of accommodation.
4. Check the latest entry information
Thailand may change some visa or entry regulations from time to time. Before flying, check the official website of the Thai Embassy or the Ministry of Tourism for the latest information.
5. Notes on filling in information
The system allows you to update most of the information you have submitted at any time before you travel. However, some important personal identification information cannot be changed, including full name, passport number, nationality and date of birth. If you need to correct this important information, you may need to apply for a new TDAC form.
With the introduction of the Thailand Digital Arrival Card (TDAC), entering Thailand will become more efficient and friendly for visitors.
