Firearm and Vape Merchants Need a Descriptor Check Whenever an Acquirer Changes Their MCC
When an acquirer moves a firearm or nicotine account to MCC 5723, 5993, or a new location record, Visa's April 2026 data rules and October 2026 dispute guide make the statement descriptor part of the change, with VAMP's 1.5% merchant line leaving little room for unrecognized charges.
