Compelling Evidence

Compelling evidence is the information a merchant provides, through its acquirer, to show that a disputed card transaction was legitimate and that the cardholder made or benefited from it. Card network rules list what types of evidence can count as compelling for different dispute reasons, ranging from signed delivery confirmations and photographs to login records and proof of earlier purchases. When the evidence meets the rules, the issuer should reverse the chargeback or, in some cases, cannot raise it at all.

The term is most closely associated with Visa, which uses it formally in its dispute rules and introduced an expanded framework known as Compelling Evidence 3.0 in 2023 to fight friendly fraud in online payments. Mastercard and other networks also specify evidence that can defeat particular claims. Compelling evidence forms part of the wider body of dispute evidence a merchant uses in a chargeback representment.

The right evidence depends on the chargeback reason code. Common examples include:

• Proof of delivery. Carrier tracking showing delivery to the cardholder's billing address, ideally with a signature or photo.
• Proof of use. For digital goods and services, logs showing the cardholder downloaded, streamed or used the purchase, with dates, times and device details.
• Customer identity links. Evidence that the person who made the purchase was the cardholder, such as the same email address, account login, phone number or device used in earlier undisputed orders.
• Terms and communication. Signed contracts, accepted terms of service, cancellation policies shown at checkout, and emails or chat messages in which the customer acknowledges the purchase.
• Travel and services. Passenger names on tickets, boarding records, hotel check-in records or evidence that a service was provided as agreed.

Evidence should be clear, relevant and organised. Large bundles of unrelated documents rarely help, and many disputes are lost because the merchant submits the wrong type of proof for the code involved.

Compelling Evidence 3.0 applies to Visa's dispute condition for fraud in card-absent environments, the most common category of fraud dispute in e-commerce. It allows a merchant to show that the disputed transaction was made by the same person who made earlier, undisputed transactions with the same card. In broad terms, the merchant must identify at least two prior transactions with that card, made between 120 and 365 days before the disputed one, that were not reported as fraud. These transactions must share at least two key data elements with the disputed transaction, one of which must be the customer's IP address or device identifier, with others such as the customer account or login ID or the shipping address.

When the evidence qualifies, liability for the dispute moves to the issuer, and the issuer cannot pursue the chargeback further on that ground. The data can be submitted during a dispute or, through Visa's pre-dispute tools, before a chargeback is raised, allowing the issuer to decline the cardholder's claim at an early stage. The framework rewards merchants that capture good customer and device fingerprinting data, and it is particularly useful for subscription, digital goods and marketplace businesses with repeat customers.

Compelling evidence matters at several stages of the chargeback lifecycle. Before a dispute, it can be shared with issuers through network or industry tools so that the issuer can explain the charge to the cardholder. After a first chargeback, it is the core of the merchant's second presentment. At pre-arbitration and arbitration, the network reviews whether the evidence met the rules. Its strength directly affects the merchant's representment win rate and the share of losses that remain with the merchant under chargeback liability rules.

Compelling evidence does not override every dispute. For consumer disputes such as goods not as described, proving that a purchase was made does not answer the complaint; the merchant must address the quality or description issue. Issuers also review evidence with the cardholder and may continue disputes if new information emerges. Collecting and storing data such as IP addresses and device details must comply with privacy laws, and smaller merchants may lack the systems to retrieve it quickly. Finally, the specific rules, time windows and data elements are set by the networks and change over time, so merchants rely on their acquirers and dispute providers to keep processes current.
