Common Mistakes That Lose Mastercard Reason Code 4807 Disputes

Understanding these common pitfalls is as crucial as knowing what to do correctly. By sidestepping these errors, you significantly improve your chances of success and minimize 4807 chargeback losses.

• Ignoring the Authorization Code: Failing to provide a valid authorization code, or providing one that doesn't match the transaction, is a direct path to losing a 4807 dispute. The entire claim hinges on proper authorization.

• Late Submission of Evidence: Mastercard has strict deadlines. Submitting your evidence package even a day late will result in an automatic loss, regardless of the strength of your case.

• Generic Evidence: Sending generic terms and conditions or a basic receipt without specific authorization details, proof of delivery, or AVS/CVV matches for the disputed transaction will not be sufficient.

• Lack of Specificity in Rebuttal Letter: A vague response letter that doesn't directly address the cardholder's claim point-by-point, or fails to clearly reference supporting evidence, weakens your argument.

• Failure to Communicate with Cardholder: Not attempting to resolve the issue directly with the cardholder before the chargeback, or not documenting such attempts, can be seen unfavorably.

• Incomplete AVS/CVV Data: For Card-Not-Present (CNP) transactions, not capturing or providing robust AVS (Address Verification Service) and CVV (Card Verification Value) match results significantly weakens the authorization proof.

• Not Understanding Expiration: Processing a transaction against an authorization that has already expired is a direct violation of network rules and makes your defense nearly impossible for 4807.
