Requires payment card networks to use certain merchant category-codes for firearm dealers

This bill requires payment card networks and merchant acquirers to use specific international codes for businesses that sell firearms and ammunition in New York. Starting in May 2025, these financial intermediaries must assign the designated code to licensed gun dealers and ammunition sellers to ensure their transactions are properly classified. The law includes enforcement measures where the Attorney General can issue notices, seek court injunctions, and impose civil penalties of up to $10,000 per violation if the required codes are not used. By standardizing how these transactions are categorized, the legislation aims to improve data tracking for firearm and ammunition sales within the state.
