All you need to find out which bank is indicated in a given IBAN is the bank code contained within the IBAN itself. You can find the bank code after the two-letter country code and the two control digits in the IBAN’s fifth section. In Germany, the bank code consists of eight digits, whereas in Austria, it’s only made up of five digits.
