TLDR : Answer Summary
The poster has a Non-Immigrant O visa which they need to extend but has lost the TM6 DTAC form required by immigration. They are seeking advice on how to proceed without the form. The community suggests multiple options, including checking emails for the DTAC number, considering the possibility they might need their TM30 instead, and even the option of taking a re-entry permit and leaving Thailand briefly to obtain a new TDAC. Overall, the conversation is focused on practical next steps for dealing with Thai immigration requirements.
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.

buy a re-entry permit for your 90-days stay permit on the Non-Imm-O visa, for 1000 THB. Exit Thailand, fill out a new TDAC and submit it, receive an email with the new TDAC, re-enter Thailand, and there you are. Your Non-Imm-O will still be valid and you will have a TDAC to show

Oo Jig The TM7 paper is asking for your TM6 number. Ignore it. If you came in by air you don’t have one. Leave it blank.

They are NOT asking for a TDAC number.

You sure there not asking for your TM30?

The paper said TM6. Googled it and it said arrival DTAC. Am I missing something?
