For my DTV from the Thai embassy in Madrid, Spain, I sent all the documents in Spanish and the bank balance certification in Catalan. They accepted my documents and I have my visa.
At the DTV visa pdf document, the psasport number is included. Then in this situation I think better talk with Thailand Embassy. But my passport expires at 2032!
I can confirm that with the DTV proces from Embassy in Madrid, Spain. I sended company registration, as I'm the only shareholder, and explain my activities in Thailand: remote worker for my company, I added that in my free time I’m interested about to know Thailand country, the people, language and culture
In my experience, I sent a certified document from my bank, with my balance at that time, and this document does not say anything about whether the account is new or not.
I got DTV at Madrid’s Embassy, and I did not send my bank account movements, but only a certificate from the bank with my current balance. Embassy accepted that.
