The Merchant Codes Can Save Lives Act would prevent states from prohibiting or deterring the use of merchant category codes (MCCs) established by the International Organization for Standardization to identify firearm merchants and firearm-related transactions. The bill adds a new subsection to 31 U.S.C. §5313, creating a federal baseline that protects MCC usage for firearm-related identification.
It covers identifying firearm merchants as well as purchases of firearms, ammunition, and related components or accessories.
Beyond preemption, the act authorizes the Department of Justice to enforce the provision by bringing civil actions in the appropriate district court. The aim is to ensure uniform use of MCCs across states and to prevent state-level restrictions that could impede data classification for compliance, investigations, or public-safety analysis.
The bill focuses on data-standardization mechanisms within financial transactions rather than on broader gun-control policy.
At a Glance
What It Does
Adds new subsection (h) to 31 U.S.C. §5313 to prohibit states from prohibiting or deterring ISO MCC usage for identifying firearm merchants and firearm-related transactions. It also grants the Attorney General authority to pursue civil actions to enforce this requirement.
Who It Affects
States, financial institutions, payment processors, and firearm merchants. The rule constrains state regulatory actions and aligns data classifications used in transaction reporting and compliance.
Why It Matters
Creates a uniform federal standard for MCC usage related to firearms, reducing state-level variation in data classification and enabling consistent enforcement and analysis across jurisdictions.

What This Bill Actually Does
The bill sets a clear federal rule: states cannot ban or discourage the use of ISO-defined merchant category codes that identify firearm merchants or transactions involving firearms, ammunition, components, or accessories. To implement this, it adds a new provision to the federal code, ensuring MCC usage remains in effect regardless of state actions.
The focus is on how financial transactions are categorized, not on changing gun laws themselves.
Enforcement rests with the federal executive branch. The Attorney General can file civil actions in the appropriate district court to enforce the new rule, providing a mechanism to challenge states that attempt to block MCC usage.
This framework seeks to standardize transaction classification and potentially improve data quality for compliance and public-safety analysis without altering existing federal gun policy. Overall, the bill emphasizes data standardization within the financial system as a tool for public safety and regulatory consistency, while delegating enforcement to the federal judiciary and executive branch.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- National banks and payment processors that rely on standardized MCC classifications for risk management and regulatory reporting.
- Card networks and merchant acquirers that process firearm-related transactions and rely on consistent MCC data.
- Federal law enforcement and regulatory agencies that monitor firearm commerce with uniform data standards.
- Policy researchers and think tanks that study firearm markets and public-safety trends using MCC-derived data.
Who Bears the Cost
- State governments that would need to adjust or relinquish existing restrictions on MCC usage, potentially losing regulatory leverage.
- State court systems that may face increased civil litigation related to enforcement actions.
- Small, cross-state financial intermediaries that must align with federal preemption and comply with enforcement mechanisms.
- Privacy advocates who worry about broader sharing and use of transaction data in firearm-related classifications.
Key Issues
The Core Tension
Balancing the benefits of uniform data classification for public safety and regulatory compliance against states’ rights to regulate data practices and the risk of broader surveillance or data misuse.
The bill foregrounds a tension between uniform federal data standards and the states’ traditional authority over local regulation. By preempting state restrictions on MCC usage, it reduces state policy experimentation and allows centralized data classifications that can support enforcement and compliance efforts.
But expanding federal data usage for firearm-related transactions also raises questions about privacy, data accuracy, and potential unintended consequences for merchants and consumers. The enforcement mechanism—civil action by the Attorney General—could shift litigation risk toward states with divergent interpretations of MCC data, even as it accelerates standardization efforts.
