ORIGINAL POSTER

I created my TDAC as I'm flying back to BKK tomorrow and I forgot to enter my DTV visa number. There's a link to update the TDAC if there is an error but the link isn't working; I'm getting a server not found error. What should I do - keep trying? Create another one? Just explain what happened to the immigration officer in BKK?

TLDR : Answer Summary

If you forgot to enter your DTV visa number on the TDAC, rest assured that it is an optional field and not mandatory. You can simply leave it blank, as immigration officers are unlikely to check it. Upon landing in Bangkok, if you encounter any issues, you can address them at one of the terminals where assistance is available. Alternatively, if you wish to create a new TDAC, you can try that, but it's generally unnecessary.

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.

These sites are operated by AGENTS CO., LTD., a trusted company that has served hundreds of thousands of travelers to Thailand.

The official TDAC service 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.

Participante anónimo 381 I was suggesting a non-verified alternative. For the Korean K-ETA or Canada ESTA (or whatever the name was, I can't remember) the instructions mention that if something that can't be modified is wrong, like name or passport number, etc., you need to file a new one. I haven't filed any TDAC yet, tho.

Anonymous participant 381 I went to file a new one and didn’t know there was a button on that website where I could update one I’d already done. The button worked fine. I did the update the hotel printed it. I’m on my way.

The visa number is NOT a mandatory field

It is 100% OPTIONAL 😉

Only the fields with the red asterisks are mandatory

Leave it blank no one will care at passport control at all

Notice it has no red asterisks 🙂

You can do it upon landing. They have terminals with helpers. I flew in Saturday but completed TDAC online. They did not even want to see it on my phone as it is all tied to your visa number they have on screen. If yiu cannot fix yourself go to one of the terminals upon landing.
