Just something I was wondering about and maybe someone will have an answer. At the moment I have the yellow book which I obtained using my present address. What happens in respect of yellow book if I were to move to a new address. Does it just become invalid or can it be updated to a new address. Thanks for any help.
TLDR : Answer Summary
If you move to a new address in Thailand, you can update your yellow book with the new information rather than it becoming invalid. It is recommended to inquire at your new Amphur about their specific procedures for updating your address.
