The official TDAC form ( only allows submissions within 72 hours of your arrival in Thailand. Once you’re within that window, you can even submit after landing, directly from the airport.

If you'd prefer to complete your submission earlier, we offer an optional early submission service for 272 THB here:



With this option, your form is automatically submitted at the very first minute you're eligible—midnight at the start of your 72-hour window—ensuring the fastest possible approval (can be useful depending on connecting flights, layovers, and travel plans).

More details about this system, its also free if you are within the 72 hour window:

The government system sometimes has errors like this where the download is not available, and the email does not get sent, or even worse you are sent someone else's TDAC.

If you're within the 72 hour window you can use our system here for free which overcomes both of these issues, and detects them:

No one needs to contact us — the system is secure and fully automated.

Edits can be made through our secure interface, and the entire process has already been vetted by the relevant authorities.

Please refrain from making baseless claims unless you’ve actually used our system.

Meeting point depends on the airport, and flight.

You will be contacted with details about the meeting point and asked to send a photo of yourself in the clothes you'll be wearing, so you can be easily recognized.

Additionally please read this screenshot from the official government page related to agents, and submissions.

Your post is completely misleading. We are not in any kind of trouble. Not to mention the main point of this post was related to FastTrack services.

Our TDAC service has been reviewed by multiple government agencies and is fully compliant with all applicable regulations. Travelers explicitly authorize us to submit on their behalf, and everything is handled with transparency.

Please avoid making assumptions or spreading false information. Our form includes the same declaration section as the official version, and travelers are clearly informed that they must keep their health status updated. Updates can be made right up to the day of travel if needed.

Theres a great overview of the service here:



The country list on our platform is fully synchronized with the official TDAC form and reflects the same source. We are the only service that ensures full compliance with this standard, and there's a reason we’ve gone the extra mile to maintain that level of accuracy. 0a30d?cate=5d5bcb4e15e39c068d3

You will see that option after you complete the first page of the TDAC.

Once submitted there will be a follow up step related to the Fast Track services, and our team will reach out to confirm additional details if necessary.

Also if you decide to use our services multiple times you can reuse your previous TDAC by logging in, and copying the previous TDAC.

This is a real service, you can read our reviews here:

But this post is specifically about FastTrack services, not the TDAC (which is included in this case)

@Jeremy *******

Max is 72 hours before arrival date with the government form.

The link posted in the original post is also FREE if you are within the 72 hour window.

@Jeremy *******

This is for our FastTrack, and Pre-Screen which also includes early TDAC submission.

Meaning if you plan to fly in/out of the country you can submit your details many days in advance, and arrange FastTrack service in one go.

The early submission service normally is charged at 272 THB (but is included in this case for free).
