Frequently Asked Questions

What is a Swift Code?

A Swift code/BIC is an 8–11 character identifier for the payee’s bank (bank, country, location, and branch). Example format: AAAA BB CC 123

What is an IBAN?

An International Bank Account Number (IBAN) is used in many countries for international wires (up to 34 alphanumeric characters). Not all countries use IBAN; if not, your payee will provide a local account number. See the list of IBAN-mandatory countries here.

Sending international wires to Australia: BSB numbers

Australian banks use a BSB (Bank State Branch) number similar to a routing number. When a form requests BSB in place of account number, include the account number in the Memo as FBO [account number] to help processing.

China and CNAPS numbers

For wires to Chinese bank accounts in CNY, a CNAPS number is required. If your form does not expose this field, contact Support with the CNAPS number and payment details for assistance.

UAE Purpose of Payment (PoP) codes
