Dispute rates, top reason codes, fraud patterns, and win-rate benchmarks for online retail merchants.
E-commerce and retail merchants face a mid-range dispute rate of approximately 0.8%, but volume is high due to the sheer number of transactions processed. Friendly fraud — cardholders who receive goods but claim they didn't — accounts for roughly 35% of all disputes in this vertical, making it the most common form of abuse retail merchants encounter.
Seasonal spikes in November and December add 20–30% more disputes around the holidays, as higher purchase volumes generate proportionally more contested transactions. Post-holiday returns in January and February compound the problem, as customers who are dissatisfied with gifts seek refunds through chargebacks rather than the merchant's return process.
Physical goods merchants face different evidence challenges than digital-only sellers. Delivery confirmation, signature capture, and proof that the cardholder received the item are the primary battlegrounds. Merchants who can tie device data to delivery confirmation win significantly more disputes than those relying on carrier tracking alone.
These six codes account for roughly 90% of disputes filed against e-commerce and retail merchants. Understanding the distribution helps you prioritize which defenses and data-capture practices to invest in.
| Code | Network | Description | Share of Disputes |
|---|---|---|---|
| Visa 10.4 | Visa | CNP Fraud | 28% |
| Visa 13.1 | Visa | Not Received | 22% |
| MC 4837 | Mastercard | No Authorization | 18% |
| MC 4853 | Mastercard | Not as Described | 12% |
| Amex F29 | Amex | CNP Fraud | 10% |
| Other | Various | Various | 10% |
Three recurring fraud patterns drive the majority of illegitimate disputes in e-commerce. Recognizing them early allows merchants to build targeted defenses rather than generic response templates.
Customers return items that were not originally purchased from the merchant, or claim a return was processed and dispute the charge when no refund appears. This is distinct from an INR dispute — the cardholder did receive an item, just not one they're returning. Defense requires documented return intake procedures and photo confirmation of returned merchandise condition and serial numbers.
A legitimate account is compromised by a third party who places fraudulent orders. The real cardholder then disputes the charges. In these cases, your strongest defense is showing that the order was placed from a device and IP address consistent with the account's prior login history — or, conversely, that it was flagged by your fraud tools. If your system flagged the session as anomalous but allowed it through, that will undermine your defense.
Fraudsters operate a storefont (often on a marketplace) that sells goods at below-market prices. When a consumer purchases from them, the fraudster uses a stolen card to fulfill the order through your store, shipping directly to the consumer. The consumer receives what they paid for from the fraudster's storefront; the stolen cardholder disputes the unknown charge on their card. Your business is the unwitting middle party holding the disputed transaction with no relationship to the consumer who received the goods.
Not all evidence carries equal weight. These figures represent the average win-rate improvement when a given evidence type is included in the dispute response, compared to responses that do not include it.
| Evidence Type | Win Rate Impact |
|---|---|
| Signature confirmation | +28 points |
| Device fingerprint | +22 points |
| IP geolocation match | +19 points |
| Prior purchase history | +15 points |
| AVS match alone | +4 points |
The data is clear: signature confirmation on delivery is the single most powerful evidence type available to physical goods merchants. Merchants shipping orders over $400 without requiring a signature are leaving significant win-rate improvement on the table.
Dispute volumes in retail are not evenly distributed across the year. Three seasonal windows drive the majority of spikes, and understanding them allows merchants to pre-position their response resources.
Based on dispute rate and win-rate data across the retail vertical, these are the three highest-impact operational practices for e-commerce merchants.
Visa's standard merchant monitoring program triggers at 0.9% dispute-to-transaction ratio. Exceeding this threshold puts you in the early warning program and eventually into enhanced monitoring, which carries fees and potential card acceptance restrictions. Monitor monthly, not quarterly.
Device fingerprinting at checkout is the single most cost-effective investment in dispute defense for e-commerce merchants. It costs fractions of a cent per transaction and provides the evidence that most often determines the outcome of a CNP fraud dispute. If you're not capturing it, you cannot retroactively obtain it after a dispute is filed.
The evidence data is unambiguous: signature confirmation improves dispute win rates by 28 percentage points. For orders under $400, the cost of signature confirmation may exceed the expected chargeback exposure. For orders over $400, the math almost always favors requiring it. Set this as a carrier rule, not a manual per-order decision.
Visa requires customers who file non-receipt chargebacks on three or more transactions with the same merchant to provide a written statement explaining why they continue to buy from that merchant. By processing individual items or shipments as separate charges (instead of one bundled transaction), you activate this deterrent faster if a customer disputes multiple items. The tradeoff is higher per-transaction fees, so this strategy delivers the most value for merchants with higher average order values or elevated non-receipt dispute rates.
