What about leaving Thailand with a passport and entering with a new passport but with a re-entry permit stamped on old passport?...I know that I/we will have to show both passports to the IO but can I/we write the re-entry permit number into the "visa Number" space on the TDAC even if the passport number is different?

TLDR : Answer Summary
Entering Thailand with a new passport while having a re-entry permit stamped in an old passport is permissible. When doing this, you must show both passports to the Immigration Officer (IO). It is acceptable to leave the visa number application field blank on the TDAC form as it is not mandatory. Moreover, if a visa extension or re-entry permit from the old passport is to be utilized, you'll need to transfer those details at the immigration office where the extension was granted.

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.

The visa number is not a required field, since visa exempt entries exist. I just filled one out and it was accepted. I have a 1 year non-o extension and left the visa field empty, along with all the departure date and details.

yes, that is the main point of my post as in the old times with the TM 6 paper form I/we filled the visa Number space with the re-entry permit number....but now with a new passport filling the visa Number space with the re-entry permit stamped/ linked on the old passport would maybe create confusion in this new TDAC system.

So I/we will leave that space empty. Thanks all ๐Ÿ™

You have to show both passport and than transfer your extension of visa and the re-enrty stamp at immigration office of your initial stamp to transfer to your new passport.

If you're talking about renewing a passport while you're out of the country, when you come back you present both passports. The officer will stamp you in on the new passport and make a notation that your visa/extension re-entry permit is in the old passport

Then you go to your immigration office where you got the extension and get the stamps transferred

However if you're a person who holds passports from different countries you can't swap passports w/extension re-entry when you enter. You have to enter on the passport with the extension/re-entry stamps in it

Use the new passport number for the TDAC and don't write anything in the visa number (it's not a required field) just leave it blank
