What should I do if I lost my TM6 form before leaving Thailand for Vietnam?

Good Morning,

I arrived in Feb and either didn't receive a TM6 or have lost it.

I'm going to fly out to Vietnam next week for a few days, does anyone know if I'll be issued a replacement TM6 at the airport?

I presume I wont fill out the TDAC for the first time until I'm due to return to Thailand?

Thank you for any info, I'm a little lost.

TLDR : Answer Summary
The user is seeking advice about losing their TM6 form after arriving in Thailand and whether they will receive a replacement TM6 at the airport when they fly to Vietnam. Community comments clarify that TM6 forms are not issued at airports; however, they should complete the TDAC up to 72 hours before returning to Thailand. No additional documents such as proof of funds are generally required for re-entry.
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.

There wasn't and still isn't TM6 at airports. You'll file a TDAC upon each entry, from May onwards.

No tm6 at airports, I've flown in and out of thailand 20+ over the last 2 years and never seen that.

Do the tdac up to 3 days before you fly. Lots of people forget and do it once they arrive in thailand before lining up for immigration

I guess you would only have got one if you arrived at a border crossing. You don't get a TM6 when arriving by air

There were only a couple of land borders that still used TM6 before the TDAC. Airports haven't used it for years.

There was no TM6 in February so you are good to go. Nothing to worry about. Fill in the TM6 replacement ie the TDAC up to 72 hours before return. No need to fill in departure info. Enjoy Vietnam.

Thank you, so other than filling out the TDAC before I return to Thailand I only really need my passport and (rarely but possibly) proof of funds in bank and Visa?

Anonymous participant Yeah - I doubt you will need proof of funds either.
