Yes, indeed. I extended just a month ago. I updated the Fixed Account passbook on the day of application. The bank code was B/F. I was a bit worried, since I got a new passport this year, so the bank insisted to give me a new book when I asked for the statement letter. But it was all accepted by the IO, no questions asked. In and out in 15 minutes (had an appointment).
However, the immigration charged me 500 baht for visa transfer to the new passport when I did it a month prior to the extension. No receipt, supposed to be FOC.
