Hi everyone….Is it correct that you can submit your electronic arrival card declaration no more that 72 hours (3 days) before your estimated flight arrival time….?

That is the estimated arrival time on your air ticket..?

So if you arrive at 10 am on a Wednesday …..for example….you can submit it only after 10 am on the Sunday…?

Sundays are ok..?

And can you not do it earlier than that…?

TLDR : Answer Summary
You can submit your electronic arrival card (TDAC) no more than 72 hours before your flight's estimated arrival time. However, the system is open for submission for a period that includes the day of travel, allowing you to submit it starting from midnight (0:00 ICT) three days prior to your arrival. Thus, if your flight arrives at 10 am on Wednesday, you may submit it after 10 am on Sunday. It is recommended to complete it before landing to save time, as there will be facilities available upon arrival.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be agents.co.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

"Within" 72 hours: preposition: within-

Yes three days before landing. Passport info,airline info and where you stay is what you need. Easy peasy. It is free make sure you are on the official site.

Yes within 3 days of ‘arriving’
Michael ********
@Anna ********
"Within 3 days of arrival" means that it must be completed sometime during the 3-day period immediately following the day of arrival. This is incorrect information. It must be completed within a 3 day period, before arrival.

@Michael *******
whatever🤣your understanding of within is different to mine

@Phil *****
but it’s not three days before arriving or after arriving

It’s within three days of arriving so need for me to amend my post 😁
Michael ********
@Anna ********
Not it is not. You should ammend your post ;) It is 3 days before.

Yes. Or you can do it when you land. There are machines and people to help. Obviously, saves time, doing it before.

@Michael *****
people around to help. Can even do on the airport machine for those without smart phones. Don't worry.

Technically, yes, it's within 72 hours before arrival, but the system is open for 4 days including "today" as a window for TDAC submission. (day counts at 0:00/ midnight ICT).

Check and try
