The PIN code is required and refers to the actual branch location. General, you can use the 8-digit BIC Code (SWIFT Code) for your international bank transfers. You can fill in all of them at once or just one keyword and hit enter. This IBAN validation form will verify that an entry is correct; note that it does not verify that the account exists. SWIFT is the process the Commonwealth Bank uses to send money overseas (similar to BPay used for domestic payments) and a BIC is the code that the SWIFT system uses to identify banks worldwide. New Zealand has not adopted this standard, so if you're giving your details, please provide your full bank branch account number and suffix as indicated on your statement.
