What happens if I forget to provide the payment reference in my bank transfer?

If the payment reference is missing or incorrect, there will be a delay in processing the fee payment. For this reason, ensure you enter the full reference, which consists of "EPO" followed by the voucher number and the check digit without any spaces (e.g. "EPOxxxxxxxx").

If you forget to state the payment reference in your bank transfer or you notice any mistakes in the payment reference, contact us. After two months, the payment reference will be cancelled automatically.
