Compelling Evidence 3.0 One Year On: How Issuer-Acquirer Liability Is Re-Rebalancing in Card Disputes

Visa Compelling Evidence 3.0 was the most consequential change to the card-not-present dispute regime in a decade. By allowing acquirers to demonstrate previous undisputed transactions between cardholder and merchant as evidence of legitimate intent, Compelling Evidence 3.0 deliberately raised the bar for issuers seeking to push first-party-misuse losses back onto merchants. A year into live operation, the rebalancing is producing a clear pattern of winners and losers.

Mastercard's First-Party Trust framework, introduced shortly afterwards, has applied similar pressure on the other major scheme. Issuers are now required to do more pre-dispute work to confirm that a customer claim is genuine, and merchants able to produce structured evidence of repeat customer relationships are seeing dispute outcomes shift in their favour. The interplay between the two scheme programmes is increasingly the dominant variable in CNP loss economics.

For banks, processors and large merchants, this is no longer an operational tweak. It is a strategic capability question — whether the firm can produce the right evidence in the right format at the moment of dispute, and whether its case-management and data-pipeline architecture can sustain that capability at portfolio scale.

Regulatory and Market Context

Visa Compelling Evidence 3.0 has now been live across all major Visa CNP markets for more than twelve months. Mastercard's First-Party Trust programme has expanded its eligible merchant categories during 2025 and is converging on a similar evidence model. UK and EU regulators are watching closely; the Payment Systems Regulator's 2025 work on consumer redress and the European Commission's ongoing work on the revised Payment Services Regulation both reference scheme-level dispute reform as a relevant data point.

Market data is starting to show the impact. Several large CNP merchants are reporting first-party-misuse loss reductions of 15 to 25 percent year-on-year, concentrated in the subscription, digital-goods and travel segments. Issuer-side data, by contrast, shows that first-party dispute volumes have continued to grow in absolute terms — meaning the regime has shifted who pays, not how often customers dispute.

What the Data Is Showing

The single biggest determinant of merchant outcome under Compelling Evidence 3.0 is the quality of the merchant's stored customer-relationship history. Merchants with deep previous-transaction histories, consistent device and address fingerprints across purchases, and structured order-confirmation data are winning a materially higher share of disputes than merchants relying on basic AVS and CVV records.

On the issuer side, the operational impact has been a sharp re-investment in pre-dispute verification — banks intervening with the cardholder before a chargeback is raised, often via in-app conversational verification, to confirm whether the disputed transaction is genuinely unrecognised. The institutions investing in this layer are seeing both lower operational cost and lower regulatory complaint volumes than peers that route disputes directly to chargeback.

Implications for Financial Institutions

Banks and processors that respond effectively are taking three steps in parallel. They are rebuilding their dispute case-management architecture so that merchant-side evidence is ingested in a structured, scheme-aligned format. They are integrating pre-dispute intervention into the cardholder app experience, not as a customer-service afterthought but as a primary loss-control tool. And they are realigning their fraud, dispute and customer-experience teams around a single chargeback economics model.

Merchants — and the acquirers that serve them — are taking the parallel step of investing in customer relationship data as a defensive asset. The merchants winning the highest share of disputes are not necessarily those with the lowest fraud rates; they are the ones whose data infrastructure can produce a Compelling Evidence 3.0-compliant case in seconds for any disputed order across years of transaction history.

Conclusion

Compelling Evidence 3.0 has done what the schemes intended — it has rebalanced the incentives in CNP disputes toward better data and more honest outcomes. The institutions that will benefit most from the next phase are those that treat dispute infrastructure as core fraud and revenue infrastructure, not as a back-office operations function. The cost of getting this wrong is no longer hidden in merchant fees — it now shows up directly on the chargeback line.

Suggested Next Steps

• Audit your dispute case-management architecture for Compelling Evidence 3.0 and First-Party Trust readiness — focusing on whether you can ingest, store and present scheme-aligned evidence in real time at portfolio scale.

• Build pre-dispute cardholder verification into your mobile and online banking experience as a primary loss-control intervention, not a service afterthought.

• Invest in stored-customer-relationship data as a defensive asset — device, address, behavioural and order-history records that can be retrieved in a Compelling Evidence 3.0-compliant case in seconds.

• Realign your fraud, dispute, customer-experience and finance teams around a single set of chargeback economics metrics so the trade-offs are visible at the executive level.
