I am an Australian and was approved for a DTV in September. I received the approval email with QR code, however I have been unable to travel to Thailand since. The application process stated that you should only apply for a DTV if you will be arriving in Thailand within the next 3 months (which I now won't). Will they cancel my DTV if I haven't used it? Does it need to be "activated" within a certain period after obtaining it?
TLDR : Answer Summary
If you hold a DTV approved visa but haven't traveled to Thailand within the 3-month guideline stated during the application, it is generally safe. The issued visa does not require activation within a specific period, and you can enter Thailand any time before the visa's expiration date, which is typically up to 5 years after issuance. The 3-month time frame is mainly a recommendation for applying rather than a strict rule for using the visa.
