Visa's April 2026 Rule Update, Read for What Actually Matters

Two of Visa's April changes will actually reach a small merchant's desk.

The 18 April 2026 Visa Core Rules ran to several hundred pages of editorial revision, almost none of which will alter how a small merchant experiences the dispute regime. The exception is a single line in the Acquirer Monitoring Program section: the merchant Excessive threshold dropped from 2.2% to 1.5%, effective 1 April 2026 across the US, Canada, the EU, and Asia-Pacific. Merchants comfortably inside the Standard band at 1.8% are now inside the Excessive band and paying $8 per disputed or fraud transaction.

The other substantive change is the integration of Compelling Evidence 3.0 into the Order Insight pre-dispute pathway. CE 3.0 was previously a representment-stage framework, accessible only after a dispute was filed and only on Visa 10.4 fraud cases. From April, its prior-transaction signal is surfaced to the issuer during cardholder inquiry, before the dispute lands. The scope remains 10.4 alone; merchants whose disputes are mostly 13.1 or 11.3 gain nothing.

Everything else, including the staged rollout of Dispute Intelligence and the Visa Dispute Resolution Network, is tooling for acquirers and issuers. It will reach merchants indirectly through their processor's interface over the rest of 2026. The 13.x condition definitions and the time-window structures under AI10681 received no substantive revision. For merchants whose dispute portfolio is mostly 13.x, the April revisions deliver almost nothing they will notice.
