Just completing my TDAC for entry back into Thailand, the departure date is not mandatory, has anybody had any issues leaving this blank?

I already have my DTV this is my first exit.

TLDR : Answer Summary
The departure date is not mandatory on the TDAC form for re-entry into Thailand, and several users have reported no issues with leaving it blank. For added peace of mind, some recommend purchasing a low-cost onward ticket.
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 doesn’t have an * next to it so it’s not mandatory 👌

I doubt you will have issue but if you want peace of mind pay the $10-$15 for an onward ticket to use for departure

No issues leaving it blank. Done it twice now.
