About the TDAC and this assistance service

TDAC stands for Thailand Digital Arrival Card. Most non-Thai nationals must complete and submit it on the official Immigration Bureau website before arrival. It is an arrival declaration, not a visa.

No. A TDAC is not a visa and does not set your length of stay. It should not be read as “valid for 30 days” or “allows a 30-day stay”. How long you may stay still depends on your visa or visa exemption and on the decision of immigration officers when you arrive.

Most non-Thai nationals need a TDAC, including infants and children. This usually applies to arrival by air, land, or sea. Each arriving traveller typically needs their own card.

If you are transiting in Thailand and will not pass through immigration, a TDAC is generally not required. If you will enter Thailand and then continue your journey, you should file as an arriving traveller.

It can be submitted up to 3 days (72 hours) before arrival, including the arrival day. A new card is required for every entry; you cannot reuse a previous one.

No. The official form is free at tdac.immigration.go.th. There is no government fee for the form. If you file it yourself, use only that official address and avoid look-alike websites.

Because you are asking us to review the details, file on the official website at the right time, and send the confirmation to your email. That is an independent assistance fee, not a government charge. You can also complete the official form yourself at no cost.

Yes. We review them immediately, file on the day the official system accepts submissions, and tell you that filing date. You do not need to remind us, and there is no extra fee. The 24 / 12 / 4 hour processing times start only after the official window opens.

The official form must be completed in English. Please give names as they appear in English in the passport. The application form also reminds you to use English letters for official filing fields.

Up to 10 travellers in one application, which matches the official limit.

Most details can be updated before arrival. The full name, nationality, and date of birth cannot be changed. If those are wrong, a new card must be filed. The latest valid record is the one that counts.

After a successful official filing there is a confirmation with a QR code, which you should keep on your phone or as a printout. We send that confirmation to the email address you name. The official message may also say whether you can use automated gates; rely on what that message states.

You can request a full refund any time before we start or complete filing on the official website. The amount refunded is the assistance service fee. Payment is processed by Stripe; this site does not store card details.

Passport numbers and dates of birth are used only to complete and support that official filing, are sent only over HTTPS, are not kept long term, and are never sold. The public application form now collects those details solely so we can file. We do not ask you to upload a passport scan. See the privacy notice.

No. Visit TH Arrival Assist is an independent assistance service, not affiliated with, authorised by, or in partnership with the Thai government or the Immigration Bureau. The official website is only tdac.immigration.go.th.

You can submit an assistance request. After you send the form, pay the service fee on Stripe’s secure checkout. We file at tdac.immigration.go.th in the official 3-day window only after payment is confirmed, then email the QR confirmation to you. The official form remains free, and you may also file it yourself. You may request a full refund any time before official filing.
