IBAN Structure Austria

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Austria's IBAN has 20 characters in the format ATkk BBBB BCCC CCCC CCCC. It opens with the country code AT and two check digits, followed by a 5-digit bank code (Bankleitzahl) and an 11-digit account number. Austria has required the IBAN for all bank transfers since February 2014. The MOD-97 check digits (ISO 7064) guard against input errors and are derived from the remaining characters. As a euro-area and SEPA member, Austria needs only the IBAN for euro transfers within SEPA — the BIC is no longer required, and payments cost the same as a domestic transfer. For payments to non-SEPA countries a BIC may still be needed.
