An unpostable payment is a BPAY payment that is unable to be posted to an account at the Biller, for example a payment made to a closed credit card.

An unpostable payment is generally caused by a CRN that passes the validation checks but does not link to an account at the Biller.

When an unpostable payment occurs, the Biller must contact their Biller Institution immediately. The Biller Institution will contact the relevant Payer Institution in order to have the payment returned to the payer. This is a key advantage BPAY has over other payment methods.

If you have any further questions please contact your financial institution.
