Following the abolition of the TM6 form, Thai immigration authorities have replaced the old paper-based entry formalities with a digital process: the Thailand Digital Arrival Card (TDAC Thailand). From May 1, 2025, all foreign travelers to Thailand, regardless of their visa status or length of stay, must complete the TDAC before they are legally allowed to enter the country.

This page explains what the TDAC Thailand is and why the government requires it. You will also find a step-by-step guide on how to complete it, so you can avoid travel disruptions.

What is TDAC Thailand?

The TDAC Thailand is a new digital entry form designed to assist immigration authorities in registering foreign nationals upon arrival in Thailand. It aims to prevent the entry of criminals and improve the safety of both visitors and residents. It also includes a health declaration to help curb the spread of infectious diseases from abroad.

The TDAC replaced the TM6 form, which was discontinued in 2024. Visitors had to fill out this paper form, present it to the border official upon arrival, and keep it to present again when leaving Thailand. It was also required for certain entry formalities, such as the Thai 90-day declaration.

Instead, after completing the online form, you will now receive an electronic confirmation of your TDAC registration, which you must present to a border official, similar to the old TM6 requirement.

Who has to complete the TDAC Thailand?

All non-Thai citizens must register for a digital entry card before entering Thailand. This applies to holders of all types of Thai visas, from the standard tourist visa to long-term stay visas such as the DTV visa and the Thailand Privilege visa.

The TDAC form must be completed for each entry into Thailand, regardless of the point of entry or mode of transport (airplane, land, or sea). Each member of a family traveling together must also complete a TDAC form. However, the online system allows for joint applications to simplify the process.

Is the TDAC a visa?

No, the TDAC Thailand is neither a visa nor a travel document. While it is required for entry, it does not authorize you to enter Thailand. You still need a visa to enter Thailand.

If you are eligible for Thailand's visa waiver program, you do not need a visa before entering the country, but you must complete the TDAC form. Otherwise, you will experience delays at the border, as entry will only be granted after the form is completed.

How to register online for the TDAC Thailand

Before you begin the registration process for the Thailand Digital Arrival Card, there are some important facts you should consider.

  • You can register for the TDAC up to 3 days (72 hours) before your arrival. For example, if you plan to arrive in Thailand on May 1st (the day the TDAC requirement comes into effect), you can start the registration process on April 28th.
  • You can fill out the TDAC on the day of your arrival.
  • There are no fees or payments required to participate in the TDAC.
  • The instructions are available in five languages: English, Chinese, Korean, Russian and Japanese.

    Thai immigration authorities are planning to launch an app for the TDAC form and integrate it into various online platforms to offer travelers multiple registration options. However, for the time being, registration via the official TDAC website of the Thai immigration authorities remains the most reliable method.

    Before you begin, please have your passport ready. Also, bring your travel and accommodation booking confirmations or receipts, as these are required for registration with TDAC Thailand. You will need to provide your flight or vehicle registration number and the address of your accommodation.

    TDAC Step 1

    Visit the official website and first select "Entry Card". You will then be asked to provide your personal details, including your nationality, travel document number, and telephone number. Only the fields marked with a red asterisk are mandatory.

    Once you have filled in these fields, proceed to the next page.

    TDAC Step 2

    Next, you will need to provide details about your arrival in Thailand and your accommodation. Departure information is not required for this process; however, depending on your visa, you may be required to present proof of onward travel upon arrival in Thailand.

    Finding the full address of your accommodation may take some time, but the system will help you narrow down your search. Once you've selected a province, the dropdown menus for district and sub-district will change accordingly, showing you the relevant options for that province.

    TDAC Step 3

    Now go to the next page where you will need to fill out a health declaration. This simply involves stating where you have been in the last two weeks. If you have been to a country for which Thailand has issued a health warning or travel advisory, you may be required to show proof of vaccination or undergo a health check upon arrival.

    TDAC Step 4

    Here you can select "Add other travelers" if you are traveling in a group and want to process all TDACs at once. Otherwise, simply follow the on-screen instructions to submit your TDAC application. You will receive electronic confirmation of your approval via email. Save this confirmation to your device and back up a copy online, ideally in cloud storage, so you can access it at any time.

    TDAC Step 5

    Upon arrival in Thailand and passing through immigration control, the border official will ask for your TDAC confirmation. Simply show it to them on your device; a printout is not necessary. DO NOT delete your TDAC confirmation after entering Thailand. You may need it again when you leave the country.

    Frequently asked questions about the digital entry card for Thailand

    Do you have any further questions? Here are some of the most frequently asked questions about the Thailand Digital Arrival Card:

    Is the TDAC procedure required every time you enter Thailand?

    Yes. Regardless of the type of visa or travel document you have, you must register with the TDAC every time you enter Thailand.

    When will the TDAC come into effect?

    From May 1, 2025, all non-Thai nationals traveling to Thailand must complete the TDAC form before entering the country.

    I am entering Thailand visa-free. Do I still have to complete the TDAC program?

    Yes. All foreign nationals must present a TDAC confirmation, regardless of whether they are entering with a visa or not.

    I need to extend my visa or apply for a new Thai visa. Do I need to fill out a separate TDAC form for this?

    No, but you must keep your most recent TDAC confirmation. This is required for certain immigration matters, including visa extensions and transfers.

    Is the TM6 arrival map still needed?

    No. The entry card in form TM6 has been abolished and replaced by the digital entry card for Thailand.

    How can I get a TDAC?

    Although several platforms are planned, the official website of the Thai Immigration Bureau is currently the most reliable way to complete the TDAC. A paper option will also be available initially, but this will be discontinued later.

    How do I fill out the TDAC?

    The Thailand Digital Arrival Card (TDAC) must be completed online, but this can be done using smartphones, laptops, or any other internet-enabled device. Step-by-step instructions for the TDAC can be found above.

    When does TDAC registration need to take place?

    TDAC registration can be completed up to three days before entering Thailand. There is no minimum timeframe before arrival, but processing can take some time. Therefore, waiting until your arrival in Thailand may cause further delays if TDAC registration is not completed in advance.

    Can the paper form TM6 still be used?

    Initially, the Thai immigration authorities will still accept paper entry cards to facilitate the transition to the TDAC system. However, this paper option is only temporary and will be phased out gradually.

    Do I need a vaccine to complete the TDAC?

    Generally not. No vaccinations are required for entry into Thailand, including against COVID-19. However, if you have been in a country on Thailand's yellow fever warning list, you must provide proof of yellow fever vaccination before entering the country. The TDAC (Thailand Department of Advisory and Concern) offers this option as part of the health declaration.

    Can I update my TDAC information after submitting it?

    Yes, but not everything. Most details, such as travel and accommodation information, can be changed or updated after submitting your initial TDAC application. However, personal information like your name, passport number, nationality, and date of birth cannot be changed. If you make a mistake here, you will need to register with the TDAC again.

    Do I need to present a connecting ticket or a flight plan for the TDAC?

    This depends on your Thai visa. If you are entering on a tourist visa or a visa-free entry stamp, you must provide your departure dates at the TDAC registration desk to prove your departure. If you are moving to Thailand or settling there permanently, you can skip this step.

    Is the TDAC form different from the TM30 form?

    Yes, these are two separate processes. The TM30 form is used to register your residence or accommodation in Thailand. Both forms are required to avoid legal issues, although completing the TM30 form is usually the responsibility of the landlord or accommodation provider.
