Hi there, Need some advice please..Coming to Thailand in January for a month…4 days Bangkok then a week to Vietnam before returning to Thailand…Do I need to apply for a separate TDAC to get back into Thailand from Vietnam ? Or will my original TDAC to gain entry to Thailand be sufficient? Thanks for any help…Regards George.
Answer summary
When re-entering Thailand after traveling to Vietnam, you will need to fill out a new TDAC (Thailand Digital Arrival Card). This card is required for each entry, as it serves as an arrival card similar to the old TM6. It's a quick process, typically taking only a couple of minutes to complete online.

Yes, you need to fill it out. I don't know if they see it when they scan my passport or not but they haven't asked to see it on my phone when I came and then went to Vietnam for 1 week. They send many people away once they get to the front to go fill it out.

The TDAC replaces the old TM6. It seems people are overthinking the whole online process. You do it each time you enter. It takes two minutes. The old TM6, by the time I fumbled around looking for a pen, I could have completed and submitted the TDAC. It's a huge improvement

So if you do it online you just save it to the phone or does it have to be printed off ?

Save it on phone. I don't print anything these days. You'll get people saying "make sure you print it" - it's all codswallop. Phone is fine

If you're arriving, you fill one in. Obviously if you leave you are no longer there and if you go back, you are arriving! It's an arrival card.

EVERY entry in Thailand requires a TDAC. It's an entry card. When you enter you need to do one.
