Mastercard
Chargeback 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.
Reason codes are meant to tell merchants why a cardholder requested a Mastercard chargeback. In the event of alleged criminal fraud or merchant error, the code returned with the transaction identifies the reason behind the chargeback, potentially exposing faults in the merchant’s processes.
It’s a good idea, but Mastercard’s new reason codes still have the fundamental problem we saw before the overhaul: they can be spoofed by friendly fraudsters. Additionally, the card network has not yet officially retired the legacy reason codes, which can cause confusion. The reason codes listed below provide some insight, but they will seldom tell the full story.
