The ARN, or Acquirer Reference Number, is a unique identifier used to track refund transactions made by credit or debit card.
This number allows your bank or card issuer to precisely locate where the refund is in the banking system.
If your refund has been processed and it exceeds 20 business days without appearing on your account, you should be able to obtain the ARN directly on your order page or through AliExpress customer service.
With this ARN, the customer service of your bank, especially those handling chargebacks or disputed payments, can more easily find and verify the status of your refund.
