General Information about Reason Codes

In 2016, Mastercard chargeback reason codes were condensed and consolidated, in a restructuring that resembled Visa Claims Resolution. Prior to this, Mastercard’s list of reason codes was long, convoluted, and confusing; now there are fewer than ten different reason codes relevant to most merchants. All the old reasons are still there, but they’ve been grouped under more comprehensive “umbrella” codes.

American Express Chargeback Reason Code R03: Insufficient Reply

What is American Express Chargeback Reason Code R03?

The American Express chargeback reason code R03 indicates that your reply to an inquiry was insufficient to address the dispute. Chargebacks with this code fall under the “inquiry/miscellaneous” category and are closely related to R13. For R03, the reason for the chargeback is known, but American Express is unsatisfied with your reply.

When that happens, the chargeback will be processed. You still have a chance to fight it, as seen shortly. There’s a window of twenty days to reply.

American Express can send inquiries to merchants because it acts as a card network and an issuer. Hence, expect chargeback inquiries from American Express through your acquiring bank. It does this to gather more information about a dispute the cardholder raises.

Your reply will help American Express resolve the cardholder’s complaint. Things will escalate to a chargeback when the issuer does not receive a reply or your response is unsatisfactory.

You have to investigate the cardholder’s claims based on the information provided in the inquiry. It is up to you to be as detailed as possible to convince American Express that you are not at fault.

Online and offline businesses are susceptible to chargebacks under this reason code. You can receive inquiries through your email or mail service.

Thorough replies to American Express’s inquiries should prevent chargebacks under this reason code. We’ll explore possible scenarios that will cause the issuer to escalate to a chargeback. That will help you when fighting the chargeback.

Why Did It Happen?

Chargebacks under reason code R03 occur when American Express deems your response or evidence to an inquiry insufficient.

The issuer will send inquiries through your acquirer to further investigate a cardholder’s claim. Within this period, you have a chance to convince American Express otherwise. You’ll need relevant facts to counter a cardholder’s claims regarding a disputed charge.

By American Express’s standards, the following are the causes for chargebacks under reason code R03:

  • Your reply contained information or an insufficient explanation to address the dispute. Or, your reply failed to address specific claims the cardholder made.
  • Your reply did not contain your cancellation, return, or refund policy or terms and conditions needed to address the cardholder’s claims.
  • Your response omitted specific documents or information that American Express specifically requested.
  • Your reply or documentation did not address the disputed charge. You may have mentioned a different amount than what is in the inquiry.
  • You may have explained that you have processed a partial credit to the cardholder. However, your response failed to explain why you’ve not processed a full refund. This could be because of your non-refundable cancellation policy, where you keep back a specific percentage.

You can do your best to address an inquiry and still incur this chargeback. This will be an opportunity to learn what you missed in your response. You can also learn what American Express expects from merchants when replying to inquiries.

If this is your first time receiving a chargeback under reason code R03, there’s no need to panic. Prepare your response thoroughly and ensure that the loopholes are addressed.
