A National Clearing Code (NCC) is needed for payments to an account without an IBAN. If you do not have the Payee's account details in this format, please ask the Payee to supply them. They can get these details on request from their bank.
If you are making a payment to Australia, New Zealand or South Africa, they may require you to enter a BSB number, please enter this in the NCC field.
If you are making a payment to America they may require you to enter a routing or Fedwire number, please enter this in the NCC field.
