Understanding Chargeback Reason Codes

Every dispute has a reason, and it shapes your response. Here is how to read reason codes.

Quick answer

A reason code states why a customer or bank is disputing a charge, and it shapes your entire response. Reading the underlying claim, not just the label, tells you which evidence will actually persuade, so you answer the specific issue rather than sending a generic reply that misses it.

The reason shapes everything

A chargeback comes with a reason code that says why the customer or bank is disputing. That reason determines what evidence will actually be persuasive, so understanding it is the starting point of any response. Related: Building a Strong Evidence Packet

Different reasons, different proof

A dispute claiming the item never arrived is answered with delivery proof; one claiming the charge was unauthorized needs different evidence entirely. Matching your response to the reason is what makes it effective. Related: Meeting Dispute Deadlines

Read past the label

Reason codes can be vague or even inaccurate. Reading the underlying claim, not just the label, helps you understand what the customer is really disputing and respond to the actual issue. Related: How do you respond when a customer says they were charged twice for a single order?

Respond to the specific claim

A generic response ignores the reason and often loses. Addressing the specific claim head on, with evidence chosen for it, is the difference between a packet that answers the dispute and one that talks past it. Related: What Banks Look For in Evidence
