Last updated 25 August 2016

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. For payments being sent from Australia to an IBAN mandatory country, an IBAN must be included. 

For those not listed, the IBAN may be optional or not required (for example the USA).

An IBAN is required for the following countries:

If the IBAN is missing or incorrect, a charge may be applied by the receiving bank and your IMT may be rejected. These charges may be deducted from your payment or charged back to you.
