Acquirer Reference Number (ARN) is the tracking information for your bank or card company to locate the refund.
For most debit/credit card refunds that have been successfully processed over 20 business days, there will be the ARN on the order page, or provided by our customer support.
With this number, the issuing bank, especially the department at the bank which deals with chargebacks or disputed payments, is able to help you find the refund. Thus, you may provide the ARN for your bank/card company to locate the refund.
