IBAN - International Bank Account Number

Based on European Commission Regulation No. 2560/2001 on cross-border payments in euro to European Union countries, it is necessary to indicate account number in the IBAN format for cross-border payments.

IBAN - INTERNATIONAL BANK ACCOUNT NUMBER (hereinafter only “IBAN“) entered into force on January 1, 2002 in the following countries: Belgium, Denmark, Finland, France, Greece, Netherlands, Ireland, Iceland, Luxembourg, Germany, Norway, Poland, Portugal, Austria, Spain, Sweden, Switzerland, Italy and United Kingdom.

IBAN consists of alphanumeric characters that uniquely identify a client’s account number held at a foreign bank. Clients of foreign banks are informed about the existence, use and usefulness of the IBAN.

The aim of the IBAN is to make automatic processing of cross-border credit transfers easier (in case of incorrect IBAN, or in case the account number is not quoted in the IBAN format, the payment is processed by the foreign bank manually).

General structure of IBAN:

  • country code (two characters, e.g. AT),
  • check digit (2 numeric characters),
  • numeric bank code (according to BLZ, AT…, or according to swift abbreviation),
  • account number itself.
