Mastercard 4854: Cardholder Dispute: Not Elsewhere Classified (U.S. Region Only)
What the cardholder is claiming
A U.S.-only catch-all, used when both banks are in the United States. The cardholder has a complaint about the purchase that does not fit the standard dispute categories, says they tried to resolve it with you first and got nowhere, and is asserting the kind of claim they could raise under U.S. law.
The evidence that actually wins
Bank analysts skim responses in minutes against a checklist for this exact code. Lead with the strongest fact; never make them dig.
- ✓Your complete correspondence history with the cardholder, showing you responded and attempted resolution before the chargeback
- ✓The terms, disclosures, and refund policy the cardholder agreed to at checkout, with proof of acceptance
- ✓Proof the goods or services matched what was sold: listings, photos, delivery confirmation, service or usage logs
- ✓A point-by-point rebuttal of the specific written complaint the issuer attached, not a generic template
- ✓Records of any refund or credit already issued on the same transaction
The honest read
Because this is a catch-all, the issuer has to include the cardholder's actual complaint, so read it before you assemble anything; your response must answer their specific story. The prior-resolution requirement cuts both ways: if their email sat in your support queue for three weeks, that silence becomes their best evidence. When the complaint is basically legitimate and the amount is small, a refund is usually cheaper than a documentation fight you might deserve to lose.
Nobody can promise you a win; the cardholder's bank decides. What you control is submitting the strongest complete case your records support, on time. Our plain-language guarantees say exactly what that means.
