TLDR : Answer Summary
The user expressed concern over not receiving confirmation for their TDAC submission before boarding a flight to Thailand. Many commenters suggested checking spam folders, verifying the correct website was used, and reassured that as long as the information was correctly submitted, it would be reflected in immigration systems. They noted that completing the TDAC form at the airport is also an option if needed, and there is generally no penalty for failing to submit it in advance.
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.

It usually comes back right away. Don't stress though. If it doesn't arrive there are machines everywhere at the airport where you can do it again before passing through immigration counters. Not ideal if it's busy but you do have options still on arrival

Just deal with it when arrive in the morning.

Did you have to pay for it? Bc if so you definitely got scammed. Worst case scenario there is an entire waiting area just for people to fill out the tdac.

Nick Tiliakos no worries, not all the scam sites want money BTW. Some just want to steal all your data to use or sell. As others have told you here though it's no problem to do it on arrival and they have terminals at the airport.

Safe travels & hope you have a great holiday in TH.

If it's not arrived and not in your spam folder, I suggest something went wrong. It literally takes seconds for the confirmation.

But as someone mentioned, you can also complete it at the airport on arrival, or try again on the plane, if you have connectivity. Just triple check all of the information, passport number, etc.

What site did you use? The official site will email you immediately and also allow you to download the QR code on completion. If you have entered everything correctly then immigration usually won’t ask you because it will show on their system as being filed.

As long as you entered the correct passport number and information, it will show on the passport control officer's computer that you completed it. That's all that is needed, you don't need any confirmation if you know it's done.
