Do I need to do another TDAC when returning to Thailand after visiting Vietnam?

ORIGINAL POSTER
I entered Thailand last week, got the usual 60 day stamp. I stayed 3 days and then flew to Vietnam for 10 days. After this, I will be returning to Thailand for the rest of the holiday for approximately 2 weeks before flying home.

My question is, do I need to do another TDAC on arrival back to Thailand?

TLDR : Answer Summary
Yes, you need to complete a new TDAC upon your return to Thailand, as each entry requires a fresh TDAC regardless of previous stays.
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.

Preferably do the TDAC within 3 days of your arrival back in Thailand. Saves having to do it before passing through immigration on arrival.

Seems sensible Todd!

Is this unnecessary bureaucracy? A question not a statement note please!? Alongside the seemingly more strick interpretation of visa exemption stamp regulations,more visitors/ tourists are allegedly heading for neighbours. Laos, Vietnam,and even the Phillipines. This has allegedly been reported by the Thai Tourist Authority. This is a crying shame and needs to be addressed.

Lots of other countries also do a digital arrival card. We recently went travelling for three days and had to do one for Malaysia and another for our return to Thailand. Better to do it before landing - less stress

It’s an arrival card. What’s the issue?
Mark *******
There isn't really an issue Stuart,apart from the fact after a long flight and being tired,I made a few elementary mistakes on the computer at the airport. And did become increasingly nervous! I suffer from anxiety unfortunately! So it was a tremendous relief when it read,' TDAC successfully completed.' I confess I only arrived on a one way ticket,so was questioned further by an Immigration Officer,after clearing the arrivals desk. He was very courteous as was I,and soon stamped my passport with a 60 days visa exemption stamp. Of which I am very grateful. I guess being 67 years old and old fashioned,I found the actual paper card of years ago,a lot more comfortable!

Unsure of my plans from here; whether to go to Jomtien and apply for an extra 30 days,or visit neighbouring countries,and apply for another 60 days upon my return. Only time will yell
