What documents can confirm my address for a UK passport application while living in Thailand?

To confirm your address for a UK passport application while in Thailand, you can use several documents. Acceptable options include the TM30 form, yellow book, or blue book, which may need to be translated. Other helpful documents are a Thai bank statement printed in English, a letter from your employer confirming your address, or a Thai driving license. Additionally, if you are registered as an overseas voter for UK elections, the confirmation letter showing your Thai address is also valid.
