Understanding how your business is categorized in the payments ecosystem affects approvals, declines, and how your account is supported over time. 

For firearm retailers, MCC 5723 has moved from a general industry concept to a state-driven mandated implementation. This means your locations and sales channels can be treated differently depending on where you operate.

What is MCC 5723

MCC 5723 is the merchant category code associated with guns and ammunition retailers. Card networks use MCCs to classify merchants by primary business activity, which allows banks and processors to apply consistent authorization and monitoring rules.

How the new implementation works

The newer operational reality is that MCC 5723 is not being applied uniformly across the U.S. 

In practice, payment ecosystems are navigating a patchwork of state mandates and state prohibitions, so the same retailer can see different MCC treatment by location.

Several sources that track acquirer guidance and state policy describe the current approach as location-based. 

In that model, a processor or acquirer evaluates where you have permanent or temporary retail presence, then assigns MCC 5723 where required by law, and avoids assigning it where prohibited.

For ecommerce, the same logic can apply to how your account is structured and how sales are routed. 

If you sell ammunition online and fulfill orders across state lines, your processing setup can benefit from clear location mapping, clean descriptors, and a checkout flow that reduces bank confusion during card not present transactions.

States where MCC 5723 is required

Current guidance indicates three states mandate availability and assignment of a firearm-specific MCC, which is being referenced as MCC 5723 in merchant and payments guidance. Those states are California, Colorado, and New York.

States where firearm-specific MCC use is prohibited

Policy tracking also indicates a separate group of states prohibit the use of a firearm-specific MCC, and it is often framed as prohibiting use of a firearm retailer specific MCC for transaction classification. 

A frequently cited list includes Alabama, Arkansas, Florida, Georgia, Idaho, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Montana, New Hampshire, North Dakota, Ohio, South Dakota, Tennessee, Texas, Utah, West Virginia, and Wyoming.

Because this landscape can change, treat state lists as time-sensitive and validate requirements for your specific operating footprint before making operational decisions.

What this means for authorizations, disputes, and growth

MCC changes do not automatically increase declines, but they can change how issuing banks evaluate transactions. 

That is especially relevant when your average ticket is high, when orders are keyed or ecommerce-based, and when product descriptions and customer expectations are not aligned. 

Strong marketing strategies support payments performance when promotional language, pricing, shipping timelines, and return policies match what customers see at checkout and on receipts.

A gun-friendly payment processor can also help you structure accounts by location and channel, align descriptors with your customer communications, and reduce avoidable friction caused by mismatched setup. 

You need a partner designed for complex merchant categories and omnichannel operations. The right provider can help you evaluate account configuration and transaction presentation so your processing supports your business model across locations and sales channels.
