Quick answers about using IBANs from Australia, and how to validate an IBAN before you send money overseas.
An IBAN (International Bank Account Number) is a standardised way to identify bank accounts for cross-border payments. It includes a country code, check digits, and bank/account details to reduce errors and delays.
No. Australian banks don't issue IBANs. For domestic payments we use a BSB (Bank State Branch) number plus an account number. You'll only need an IBAN when sending funds to countries that require it (e.g. Germany, the UK, France).
When you're sending money overseas to a region that uses IBANs. Ask the recipient for their IBAN and bank name, and confirm the currency and any reference required for the transfer.
Use the IBAN Checker above: paste the IBAN and click Validate. We validate the country format, length and the Mod-97 checksum. This confirms the IBAN is correctly structured before you lodge a payment.
Yes. The check runs locally in your browser; no IBAN data is sent to our server.
Transfers can be rejected or delayed. Always validate the IBAN and double-check the recipient details with the beneficiary before you submit the payment.
An IBAN is a long alphanumeric code used widely overseas to identify accounts for international transfers. A BSB is a 6-digit code used in Australia to identify the bank and branch for local payments.
