What is the TDAC?

The TDAC (Thailand Digital Arrival Card) is the electronic arrival form introduced by Thai authorities to replace the old paper TM6 form and streamline immigration procedures.

TDAC objectives

  • Improve tourist safety
  • Facilitate communication in case of emergency
  • Provide useful information about the destination
  • Optimize tourist flow management

Is it mandatory?

The TDAC is generally required for travelers entering Thailand. The digital arrival card has replaced the old paper TM6 form as part of the Thai government's modernization of immigration procedures. Specific requirements may vary depending on your individual situation.

Certain criteria may influence the information requested:

  • Your nationality (determines certain mandatory fields)
  • Length of your stay (tourism, business, etc.)
  • Your point of entry into Thailand (airport, land border, port)
  • The type of visa you hold
Important: Official requirements change regularly. Our team updates the form in real time to stay compliant with the latest Thai government directives. By using our service, you can be sure of filling out your arrival form correctly.

Common Mistakes to Avoid When Applying for Your TDAC

Many travelers make errors when filling out their TDAC form, which can lead to delays or outright rejection. Here are the most common mistakes and how to avoid them.

1. Incorrect passport number

The most frequent mistake is entering the wrong passport number. Double-check that you are copying the exact number from the identity page of your passport. Watch out for common mix-ups between the letter O and the digit 0, or the letter I and the digit 1. A single wrong character is enough to invalidate your TDAC.

2. Mixing up arrival and departure dates

The TDAC form uses date formats that may differ from what you are used to (month/day/year vs. day/month/year depending on the field). Many travelers accidentally swap the day and month. Pay close attention to the format required for each field, and make sure your arrival date matches your flight ticket exactly.

3. Incomplete or incorrect accommodation address

Your accommodation address in Thailand must be complete and accurate. Do not just enter the hotel name -- provide the full address including the street number, district, city, and province. Copy the address directly from your booking confirmation to avoid any typos or missing details.

4. Forgetting to save the confirmation QR code

Once your TDAC is approved, you receive a confirmation QR code. Too many travelers forget to save it and find themselves without proof at the airport. Save it on your phone, take a screenshot, and print a paper copy in case your battery dies or you run into technical issues.

5. Submitting the form too early or too late

Submitting your TDAC too far in advance may render it invalid if your travel plans change. On the other hand, filling it out at the last minute leaves you exposed to unexpected processing delays. The ideal window is between 72 hours and 30 days before your departure.

6. Not checking the status of your application

After submitting your form, remember to check the status of your application regularly. Monitor your emails (including spam) so you do not miss any notifications. If you use our service, you will receive updates at every stage of the process.

Tip: When you use our assisted service, every field is automatically verified before submission. Our checks detect format errors, date inconsistencies, and missing information -- so your application is correct the first time.

TDAC Validity and Timing

Understanding TDAC timing and validity is essential for planning your trip to Thailand. Here is everything you need to know about when to apply and how long your TDAC lasts.

When should you submit your TDAC?

It is recommended to submit your TDAC between 72 hours and 30 days before your arrival date in Thailand. This window gives you enough time to correct any errors while keeping your travel information up to date.

30 days

Typical processing time

How long is the TDAC valid?

Your TDAC is valid for a single entry into Thailand and for the travel dates you specified in the form. Once it is used at immigration, it cannot be reused. If you leave Thailand and wish to return, you will need to submit a new TDAC application.

What if your flight changes?

If your travel dates, flight number, or point of entry change after you have submitted your TDAC, you will generally need to submit a new application with the updated information. Modifications are not possible once the form has been submitted. This is why it is best to wait until your travel dates are confirmed before filling out the form.

A new TDAC for every entry

Yes, a new TDAC is required for each entry into Thailand. If you plan multiple entries into the country (for example, if you visit a neighboring country and then return to Thailand), you will need to fill out a new TDAC form for each border crossing.

Processing time

TDAC processing time varies depending on the period and the volume of applications. In general, processing takes anywhere from near-instant to 24 hours. During peak travel periods (year-end holidays, Songkran in April), times may be slightly longer. When you use our service, we process your application in 1 to 4 hours on average and keep you informed at every step.

Heads up: Do not count on instant processing, especially during peak tourist season. Always allow a buffer of a few days to avoid any last-minute stress.

TDAC for Families and Minors

Traveling to Thailand with your children? Here is everything you need to know about the TDAC for families and minor travelers.

Every traveler needs their own TDAC

Every person entering Thailand must have their own TDAC form, including infants and young children. There is no family form -- an individual TDAC is required for each family member, regardless of age.

Who fills out the form for a minor?

For minor children, parents or legal guardians are responsible for filling out and submitting the TDAC form. The parent or guardian enters the child's passport information and signs the application on their behalf. If both parents are traveling with the child, only one of them needs to submit the form.

Documents required for minors

In addition to the standard documents, here is what you should prepare for a minor child:

  • The child's own passport valid for at least 6 months after the arrival date
  • Birth certificate details (parents' full names, child's date and place of birth)
  • Contact details of the accompanying parent or guardian
  • Travel consent form if the child is not traveling with both parents (depending on your country of residence's regulations)

Tips for families:

  • Fill out all of the family's TDAC forms at the same time to avoid forgetting anyone.
  • Use a single contact email address to centralize confirmations for the entire family.
  • Make sure each child's name is spelled exactly as it appears on their passport.
  • Print paper copies of the confirmations for every family member, including children.
  • If you are traveling with a young child who does not yet have a passport, the passport must be obtained before you can complete the TDAC.
Make it easier: Our assisted service lets you fill out TDAC forms for your entire family with personalized guidance. We review each application individually to ensure every submission is compliant.
