The IBAN (International Bank Account Number) and the BIC (Bank Identifier Code) are both information about your bank account.
In some countries, like Germany and Switzerland, IBANs are commonly printed on bank cards and on bank statements. The IBAN must now be used for money transfers within Germany and in the SEPA area.
Unlike an IBAN, a BIC (aka SWIFT) identifies your bank, rather than you, individually. BICs are either 8 or 11 characters long. These characters identify the bank, the country, and the location within that country. Your BIC should be in the same place as your IBAN, either on your bank card or on your bank statements.
In case you cannot find this information, we advise you to contact your bank directly.
