Question 1

What is the Thailand Digital Arrival Card (TDAC)?

Accepted Answer

The Thailand Digital Arrival Card (TDAC) is a mandatory online immigration form that replaces the traditional paper TM6 arrival card. All non-Thai nationals must complete this digital form before entering Thailand by air, land, or sea. The TDAC became mandatory on May 1, 2025, and collects essential information including personal details, travel plans, accommodation, and health declarations to streamline the immigration process.

Question 2

Who needs to complete the TDAC?

Accepted Answer

ALL non-Thai nationals entering Thailand must complete the TDAC, regardless of visa type, nationality, or purpose of visit. This includes tourists, business travelers, transit passengers, visa-exempt visitors, and those with long-term visas. Even if you have a Thai visa or are from a visa-exempt country, you still must submit the TDAC within 72 hours before arrival.

Question 3

Is the TDAC required for transit passengers?

Accepted Answer

Yes, even transit passengers who do not leave the airport transit area are required to complete the TDAC if they are connecting through Thailand. This applies to all international transit passengers, regardless of connection duration. The only exception is for passengers who remain airside and do not go through Thai immigration control.

Question 4

What is the 72-hour submission rule?

Accepted Answer

The TDAC must be submitted within exactly 72 hours (3 days) before your arrival in Thailand. You cannot submit it earlier than 72 hours, and you cannot submit it after this window closes. This strict timing requirement is enforced by the Thai immigration system and violations can result in entry delays or complications at the border.

Question 5

Is the TDAC free? Why does this site charge a fee?

Accepted Answer

The TDAC is completely free when submitted directly through the official Thai government portal at tdac.immigration.go.th. However, many travelers struggle with the complex interface, make costly mistakes, or miss the 72-hour deadline. Our service charges a fee to provide expert assistance, ensure accuracy, guarantee proper timing, offer multilingual support, and prevent the stress and complications that come with DIY submissions.

Question 6

What's the difference between TDAC and the old TM6 form?

Accepted Answer

The TDAC (Thailand Digital Arrival Card) is the digital replacement for the paper TM6 arrival card that was previously filled out on flights or at borders. Unlike the TM6 which was completed upon arrival, the TDAC must be submitted online within 72 hours before travel. The TDAC collects more detailed information and generates a QR code that must be presented to immigration officers upon arrival in Thailand.

Question 7

What happens if I don't submit the TDAC on time?

Accepted Answer

Failing to submit your TDAC within the 72-hour window can result in significant delays at Thai immigration, potential entry denial, or being required to complete additional paperwork at the border. Immigration officers may question travelers without proper TDAC submissions, leading to longer processing times and possible complications. In some cases, you may be sent to a secondary inspection area for additional screening.

Question 8

Can I submit the TDAC for my family or group?

Accepted Answer

Yes, you can submit TDAC applications for family members and group travelers, but each person requires their own individual TDAC form. Children, including infants, need separate TDAC submissions. One person can act as the group coordinator and submit multiple forms, but all travelers must have their own QR code confirmation for entry into Thailand.

Question 9

Can I edit my TDAC after submission?

Accepted Answer

Once submitted, the TDAC cannot be edited through the official portal. If you discover errors after submission, you may need to submit a new TDAC application (if still within the 72-hour window) or contact Thai immigration authorities. Minor errors might be corrected at the border, but significant mistakes could cause entry delays or complications.

Question 10

How can I spot fake TDAC websites and avoid scams?

Accepted Answer

Fake TDAC sites often use URLs similar to the official site, claim to be 'official' government portals, or pressure you with urgent deadlines. The only official government site is tdac.immigration.go.th. Legitimate private services (like ours) are transparent about being paid assistance services, use secure payment methods, and clearly explain their value proposition. Always verify SSL certificates and avoid sites with poor English or suspicious payment requests.

Question 11

Where can I get help filling out the TDAC form?

Accepted Answer

While the official TDAC portal provides basic instructions, many travelers benefit from professional assistance to ensure accuracy and proper timing. Our expert service provides step-by-step guidance, reviews all information for accuracy, ensures compliance with the 72-hour rule, and offers 24/7 support in multiple languages. We handle the entire process while you focus on planning your trip to Thailand.

Question 12

What if I lose my TDAC QR code confirmation?

Accepted Answer

If you lose your TDAC QR code, you should immediately try to retrieve it from your email confirmation or the official portal using your reference number. If you cannot recover it and are within the 72-hour window, you may need to resubmit your TDAC. Our service provides backup delivery methods and can help recover or reissue your QR code confirmation to prevent travel disruptions.
