firearms transactions; merchant codes; prohibition

SB 1143 prohibits government entities from maintaining records of privately owned firearms or their owners and bans payment networks from requiring or using merchant category codes to identify firearm retailers. It specifically prevents covered entities (like banks or payment processors) from assigning or requiring codes that distinguish gun stores from other businesses. The law applies to all government agencies, payment card networks, and firearm retailers operating in Arizona. The bill, titled the "Second Amendment Financial Privacy Act," was passed by the legislature in May 2025 but vetoed by the governor.
