TLDR : Answer Summary
The TDAC (Travel Declaration form) must be submitted within 72 hours before your arrival in Thailand. Although you can submit it right after landing at the airport, if you want to complete it earlier, there's an option for early submission for a fee. The submission fully complies with the regulations for smoother entry into Thailand.
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.

I arrived on Thursday (BKK)and didn’t even get asked for the TDAC. I had a digital version on my phone ready just in case. Big line of people doing them prior to immigration to.

THAI ******************************
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:
