Beginning Monday, a California law will require credit card networks like Visa and Mastercard to provide banks with special retail codes that can be assigned to gun stores in order to track their sales.
But new laws will do the exact opposite in Georgia, Iowa, Tennessee and Wyoming by banning the use of specific gun shop codes.
The conflicting laws highlight what has quietly emerged as one of the nation’s newest gun policy debates, dividing state capitols along familiar partisan lines.
Some Democratic lawmakers and gun-control activists hope the new retail tracking code will help financial institutions flag suspicious gun-related purchases for law enforcement agencies, potentially averting mass shootings and other crimes. Lawmakers in Colorado and New York have followed California’s lead.
“The merchant category code is the first step in the banking system saying, `Enough! We’re putting our foot down,’” said Hudson Munoz, executive director of the nonprofit advocacy group Guns Down America. “`You cannot use our system to facilitate gun crimes.’”
But many Republican lawmakers and gun-rights advocates fear the retail code could lead to unwarranted suspicion of gun buyers who have done nothing wrong. Over the past 16 months, 17 states with GOP-led legislatures have passed measures prohibiting a firearms store code or limiting its use.
“We view this as a first step by gun-control supporters to restrict the lawful commerce in firearms,” said Lawrence Keane, senior vice president of the National Shooting Sports Foundation, an industry group that backs laws blocking use of the tracking code.
The new laws add to the wide national divide on gun policy. This past week, U.S. Surgeon General Vivek Murthy declared gun violence a public health crisis, citing a rising number of firearm-related deaths, including more than 48,000 in 2022. The move was quickly criticized by the National Rifle Association.
States have dug opposing trench lines on other gun policies. On July 4, for example, Republican-led Louisiana will become the 29th state to allow residents to carry concealed guns without a permit.
By contrast, Democratic-led New Mexico this year tightened laws for people who don’t have concealed-carry permits, requiring a seven-day waiting period for gun purchases, which is more than double the three-day period for a federal background check.
States also have responded differently to recent mass shootings. In Maine, where an Army reservist killed 18 people and wounded 13 others, the Democratic-led Legislature passed a variety of new gun restrictions. Following school shootings in Iowa and Tennessee, the Republican-led legislatures there took steps that could allow more trained teachers to bring guns into classrooms.
The surge of legislation targeting firearm store category codes addresses a behind-the-scenes aspect of electronic financial transactions. The International Organization for Standardization, based in Geneva, sets thousands of voluntary standards for various fields, including category codes for all kinds of businesses, from bakeries to boat dealers to bookstores.
Those category lists are distributed by credit card networks to banks, which assign particular codes to businesses whose accounts they handle. Some credit card issuers use the category codes for customer reward points.
The codes can be used by financial institutions to help identify fraud, money laundering or unusual purchasing patterns that are reported as suspicious activities to the U.S. Treasury Department’s Financial Crimes Enforcement Network.
Banks and other depository institutions filed more than 1.8 million confidential reports in 2022 flagging more than 5.1 million suspicious activities. About 4% of annual reports lead to follow-up by law enforcement and an even smaller percentage to prosecution, according to the Bank Policy Institute, a trade group representing large banks.
Stores that sell guns have previously been grouped with other retailers in merchant category codes. Some have been classified as sporting goods stores, others as miscellaneous and specialty retail shops.
At the urging of New York-based Amalgamated Bank, which worked with gun-control groups, the International Organization for Standardization adopted a new four-digit category code for gun and ammunition shops in 2022. Major credit card networks initially said they would implement it but backed off under pressure from conservative politicians and the gun industry.
Munoz, who helped lead the effort to establish the firearms store code, noted credit cards were used to buy weapons and ammunition for some of the nation’s deadliest mass shootings.
The intent of a gun merchant code is to spot suspicious patterns, like a person with little history of gun purchases who suddenly spends large amounts at multiple gun stores in a short period. Once alerted by banks, authorities could investigate, potentially thwarting a mass shooting, Munoz said.
California’s new law requires credit card networks to make the firearms code available to banks and other financial institutions by Monday. Those entities then have several months to determine which of their business clients should be categorized as gun stores and assign them new codes by May 1.
