Same-Day Border Run and the Thailand Digital Arrival Card

On the website it says that: "Foreigners are required to submit The website says: *"Foreigners are required to submit their arrival card information 3 days before arriving in Thailand."*

If I’m planning a same-day border run, does that mean I have to submit the TDAC form while I’m still in Thailand? Could that cause any issues?

Thanks in advance!

TLDR : Answer Summary
The concern is about the requirement to submit the Thailand Digital Arrival Card (TDAC) within three days of arrival, particularly for those doing a same-day border run. Community responses clarify that you can submit the TDAC as close as right before passing through immigration, and it is acceptable to fill it out on the same day as arrival at the border. As long as it's done within three days prior to your entry, there should be no issues.
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 tdac.in.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.

Could get interesting as all border checkpoints to Cambodia are shut.

It's within 3 days of arrival meaning you can do it same day of arrival

You can complete the fom right before the immigration desk, provided you have a smartphone and connectivity.

The 3 days rule means don't do it if your arrival time is MORE than 3 days away. Anytime within 3 days is fine, including while standing in line at immigration

You can leave departure details blank too

"Up to 3 days"

You can do it at the border if you want

My friend did a day trip land border run a few weeks ago. He filled it out the day before he did the border run. It didn't cause any problems, everything was fine

No. You can do it once you arrive back. Just before passing through immigration.
