Chargeback Reason Code

A card-scheme code that classifies why a cardholder or issuer has disputed a transaction.

Definition

When a cardholder disputes a charge, the issuing bank raises a chargeback tagged with a reason code defined by the card scheme (Visa, Mastercard, and others each maintain their own code sets, grouped into categories such as fraud, authorisation, processing errors, and consumer disputes). The reason code tells the merchant why the payment is being reversed and what evidence, if any, can be submitted to represent the transaction. Reason codes matter because remedies and time limits differ by category: a fraud-coded chargeback where 3-D Secure was used may be defensible on liability-shift grounds, while a genuine processing error usually is not. Tracking reason-code patterns helps distinguish true fraud from friendly fraud.

Worked example

An operator receives a chargeback under a fraud reason code, checks that the deposit was 3-D Secure authenticated, and disputes it on the basis that liability shifted to the issuer.

Why it matters

For learners, reason codes are the vocabulary of payment disputes. For professionals, reading them correctly drives representment decisions, fraud analysis, and keeping chargeback ratios within scheme thresholds.
