Thailand Digital Arrival Card (TDAC): Everything You Need to Know 

Did you know that you now need to submit the Thailand Digital Arrival Card when entering Thailand? Here’s how to do it.

When you come to Thailand, you now need to complete an immigration form online. It’s known as the Thailand Digital Arrival Card, or TDAC for short. It replaces the old paper arrival card, known as the TM6 form.

This means you no longer need to ask for an arrival card and fill it out by hand. Instead, you can submit it online before coming to Thailand and show it to an immigration officer when you arrive.

The TDAC should make immigration faster and smoother.

In this article, we’re going to show you everything you need to know about the Thailand Digital Arrival Card, including what to do, how to file it, and what to expect.

Who Needs to Submit the TDAC?

Every foreigner traveling to Thailand needs to file the Thailand Digital Arrival Card online, whether arriving by air, land, or sea, and regardless of visa type.

There are two main exceptions:

• You are a Thai national.
• You are in transit and don’t need to pass through immigration.

This includes children and infants. Every traveler, regardless of age, needs their own TDAC.

How to Fill Out the TDAC

There are two ways you can file the TDAC: online or at the international airport when you arrive.

Let’s take a closer look at each option.

Online

This is our recommended way. It can be done in just a few minutes and saves you hassle at the airport. This means that after you arrive in Thailand, you can go straight to immigration.

The required information is pretty much the same as the paper form.

Tip: Have your passport details and travel information ready before you start. The system doesn’t allow you to save progress, so you’ll need to complete it in one session (about 3 to 5 minutes).

Here’s how to do it step-by-step:

• Go to tdac.immigration.go.th
• Click “Arrival Card”
• Enter your passport information such as name, passport number, occupation, and so on
• Enter travel details including arrival date, airport, flight number, and accommodation address in Thailand
• If you’re coming from a country that requires health control (such as certain African countries), you need to complete the health declaration form and upload a vaccine certificate*
• Add your email address
• Click “Add Other Traveler” if you want to submit the TDAC for other people in your group.
• Review the information to make sure it’s correct
• Submit the form
• Save the confirmation (either as a screenshot or printed copy)

Important: The official TDAC is completely free. Thai authorities have issued official warnings about fake websites that charge fees between US$10 and US$100 for TDAC processing. Only use the official site at tdac.immigration.go.th. Any site asking for payment is a scam.

Tip: After submitting, check your spam or junk folder if you don’t receive the confirmation email. The TDAC email sometimes gets filtered automatically.

*You can find more details on the Thailand Ministry of Foreign Affairs website

Once at immigration, just show the screenshot or printed copy to the officer. In many cases, the immigration officer just glances through it.

International Airports

Another way to submit the TDAC is at international airports. There are kiosks at five international airports: Suvarnabhumi, Don Mueang, Phuket, Chiang Mai, and Hat Yai, set up before the passport control area. The process is the same as doing it online. However, this time, there are airport staff members available to help you complete it.

Important: It’s reported that the queues at TDAC kiosks are long and disorganized due to the high number of people arriving in Thailand. So, it’s better to complete it before your arrival, allowing you to breeze through immigration. Another option is to install an eSIM on your phone before your arrival, so you’ll have internet access and can submit the TDAC on your phone while waiting in line at passport control.

When to Submit the TDAC

You can submit your TDAC online anytime within three days (72 hours) before your arrival in Thailand. For example, if you’re landing on May 5, you can submit it as early as May 2.

If you haven’t submitted it beforehand, you can still do it on the day of your arrival at the airport kiosks before passport control.

Facial Recognition and Automated Gates at the Airport

Since late 2024, Airports of Thailand has rolled out a biometric facial-recognition system at six airports: Suvarnabhumi, Don Mueang, Phuket, Chiang Mai, Mae Fah Luang (Chiang Rai), and Hat Yai. Domestic passengers got access from November 1, 2024, and international travelers from December 1, 2024.

The idea is to let you move through the airport using your face instead of repeatedly showing your passport and boarding pass. You enroll once at the check-in counter or a self-service kiosk, give consent for the system to use your facial data and passport, and from there you can pass baggage drop and the boarding gate with a face scan.

Important: If you hold a long-stay visa, such as a work permit, BOI status, a marriage or spousal visa, or Long-Term Residence, immigration advisors recommend you avoid the automated biometric gates and use a staffed immigration counter instead. The automated lanes are built around short-stay, visa-exempt tourists, and a human officer is better placed to handle the stamps and extensions your visa depends on.

This system is separate from the TDAC. Whichever lane you use, you still need to submit the Thailand Digital Arrival Card online before you arrive. The facial-recognition gates speed up the airport journey, but they don’t replace your arrival card.
