An IBAN is used in some countries to uniquely identify a customer’s bank account. The IBAN consists of an alphabetical country code followed by two digits, and then up to thirty-five characters for the bank account number. Some countries require that payment sent from Australia include an IBAN.

Ask your receiver for the IBAN if it is required in their country. You can refer to the bank account transfer details to see what details are required for each country.
