Resumo:
- What it is: A chargeback reason code tells you what the cardholder is claiming: fraud, a consumer dispute, a processing error, or an authorization issue.
- 4 practical categories: Fraud, consumer disputes, processing errors and authorization help organize the evidence; use the actual network code and requirements.
- Deadlines: Filing windows depend on the dispute condition; the merchant must follow the actual processor or acquirer reply-by date.
- Full lists live elsewhere: For the complete code-by-code breakdown, use the relevant network rules and current processor defense requirements alongside the references below.
- Biggest mistake: Evidence must address the actual dispute claim; a complete, timely submission still does not guarantee a win.
A chargeback reason code is the short alphanumeric label a card network assigns to a dispute so a merchant knows, before reading a single document, what the cardholder is claiming and what evidence may support a response.
Visa, Mastercard, American Express, and Discover each run their own list, and each network's own guide breaks its codes down one by one. This page uses four practical categories to organize reason-specific evidence and shows how to find the applicable response cutoff. Our chargeback reason codes reference adds network examples and the evidence each code needs.
4 Practical Reason Code Categories
Fraud, consumer disputes, processing errors and authorization are a useful organizing framework, also used in Adyen’s dispute guidance. The actual network code and current requirements determine what evidence to supply; category labels alone do not establish eligibility or a winning response.
| Categoria | What the Code Claims | Evidence to Review |
|---|---|---|
| Fraude | The cardholder says they never made or authorized the purchase | AVS/CVV match, device and IP history, prior legitimate orders from the same card or account, 3D Secure authentication data |
| Consumidor disputas | The cardholder made the purchase but disputes the product, service, or terms | Delivery or tracking confirmation, signed terms or refund policy, support correspondence, proof of a working item or completed service |
| Erros de processamento | The claim is about how the transaction was processed, not whether it happened | Original transaction record, proof of correct amount and currency, evidence a duplicate or credit was never actually processed |
| Autorização | The transaction ran without proper authorization from the issuer | Authorization approval code, proof the transaction matched the authorized amount and timeframe |
The same two-digit or alphanumeric string can mean something different depending on the network, since Visa, Mastercard, American Express, and Discover each maintain a separate list with its own definitions and requirements. Sending consumer-dispute evidence against a fraud claim, or vice versa, can weaken an otherwise relevant response.
Reason Codes by Network: Where to Find the Full List
Use the actual network rules and your processor’s reason-code and defense requirements for the current code definition. The references below are Chargeflow explainers, and each network can update its requirements independently.
| Rede | Code Format | Full Reference |
|---|---|---|
| Visto | Two-part numeric, e.g. 13.1 | Visa Chargeback Reason Codes, Visa Reason Code 13.1, and Visa Reason Code 13.5 |
| Mastercard | Four-digit numeric, e.g. 4870 | Mastercard Chargeback Reason Codes and Mastercard Reason Code 4870 |
| American Express | Letter plus two digits, e.g. C08 | American Express Chargeback Reason Codes and Amex Reason Code C08 |
| Descubra | Two-letter code, e.g. AT, RM | Descubra os códigos de motivo d Chargeback |
Response Deadlines You Cannot Miss
Use the response cutoff in the actual processor or acquirer notice. Cardholder filing windows and network-member response clocks are different from the time available to a merchant. The relevant reason code can also change the filing trigger and outer limit.
Find the deadline for this case
Case notice
Read the exact reply-by date and time in the processor or acquirer notice. Do not substitute a generic network window.
Processor example
On Stripe, merchant responses are usually 7–21 days depending on the network, according to Stripe’s process documentation. This range is not a universal deadline.
Evidências
Submit the required, reason-specific evidence before that cutoff and confirm the submission was accepted.
A cardholder filing limit is not extra time for the merchant to respond.
See the full breakdown, including exceptions, in Chargeback Time Limits by Network.
Common Mistakes That Lose a Winnable Chargeback
- Matching the wrong evidence to the category. Delivery confirmation does not answer a fraud claim, and an authorization code does not answer a consumer dispute.
- Treating every reason code as unbeatable. A reason code states the cardholder's claim, not a verdict. Networks still require the issuer to review compelling evidence that contradicts it.
- Missing the response window. Late submission can forfeit the opportunity to challenge the case; follow the actual notice rather than assuming a grace period.
- Refunding low-effort friendly fraud automatically. Fast-tracking every low-dollar dispute to a refund trains repeat offenders that filing a dispute is easier than requesting a refund.
- Ignoring the pattern. A cluster of the same reason code from the same product line or checkout step usually points to a fixable process gap, not a wave of bad luck.
Perguntas frequentes
Is there one master list of every chargeback reason code?
No single numbering system covers all four networks. Visa, Mastercard, American Express, and Discover each publish and update their own code list independently, while fraud, consumer disputes, processing errors and authorization provide a practical way to organize the evidence.
Can the same number mean different things on different networks?
Yes. A two-digit or alphanumeric string is only meaningful within its own network's list; Visa's format, Mastercard's four-digit codes, Amex's letter-prefixed codes, and Discover's two-letter codes are not interchangeable, even when a code happens to share digits.
What happens if I submit fraud evidence against a consumer dispute code?
The issuer reviews evidence against what the specific reason code claims. Evidence that answers a different category, like an authorization approval code submitted against a "not as described" claim, typically fails to overturn the dispute even when the underlying transaction was legitimate.
Does automating chargeback responses help with reason codes?
Automation platforms like Chargeflow read the reason code on each incoming dispute and assemble the matching evidence type automatically, which can help keep evidence relevant to the actual claim. Issuer review, eligibility and timely submission still determine the result.
Match Your Evidence to the Code, Every Time
A chargeback reason code is a claim, not a verdict, and a practical review starts with four questions: was this authorized, was it processed correctly, does the cardholder dispute the purchase itself, or do they say they never made it. Identify which question you are answering, pull the evidence built for that category, and file it before the deadline. Pairing that discipline with Chargeflow's automated evidence matching closes the gap between a reason code you can win and a response that actually wins it.
