TLDR : Answer Summary
The user is seeking clarification on whether they can extend their stay in Thailand despite having submitted their departure date on the DTAC for December 20, 2025. Comments suggest that the departure date on the DTAC is not critical as what matters is the entry stamp in their passport, which dictates their legal permission to stay. Users advise that the entry rules should be followed regardless of the DTAC submission.
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.

Tony , you don’t have to change dtac, once u entered Thailand and use it u cannot make any change anymore. Just make sure u leave Thailand before your visa exempt or visa on arrivel expires. Have fun there

Do not understand. Dtac can be submitted 3 days before traveling. So do not understand that you submitted now. Not a drac.

Your TDAC is Irrelevant. You go off the stamp in your passport. Nothing needs to be changed

Your information wasn't what I was amused by.

Look at the entry stamp in your passport. That's when you have to leave Thailand. Your permission to stay is in your passport and has nothing to do with your TDAC.
