New MCC code would also help financial institutions monitor and report suspicious activity connected to trafficking in firearms, money-laundering proceeds from trafficking in firearms, or other criminal activity

Washington (March 15, 2023) – Today, Senator Edward J. Markey (D-Mass.) joined Senators Bob Menendez (D-N.J.) and Elizabeth Warren (D-Mass.) in urging the U.S. Department of the Treasury and the U.S. Department of Justice (DOJ) to provide guidance to financial institutions for the full implementation of the new merchant category (MCC) code the International Organization for Standardization (ISO) approved last year for gun and ammunition stores. The swift application of the MCC code would equip financial institutions to flag suspicious activity for the Financial Crimes Enforcement Network (FinCEN), which could help reduce the scourge of gun violence and tackle firearms trafficking and other criminal activity.

This effort comes on the heels of recent developments, in which Visa, Mastercard, and American Express have paused the implementation of the new MCC code because some Republican-led states are actively working to block its enactment. The senators believe these credit card companies have a responsibility to push forward, and Treasury and DOJ should provide them, and other financial institutions, with the proper tools for implementation in a timely manner.

“MCCs are four-digit numbers that identify the type of business processing a financial transaction – such as grocery stores, department stores, and hardware stores. Previously, gun and ammunition stores were categorized as sporting goods stores or miscellaneous general merchandise stores,” wrote the senators to Treasury Secretary Janet Yellen and Attorney General Merrick Garland. “We strongly support the new MCC code for gun and ammunition stores…We believe the new MCC code has the potential to help reduce gun violence and save lives.”

Last year, there were 648 mass shootings and more than 44,300 gun-related deaths in the United States. In 2021, nearly 3,600 children died from gunfire, and in 2020, gun violence surpassed car accidents and became the leading cause of death for children in the U.S.

We urge Treasury and DOJ to quickly publish any policy advisory, enforcement guidance, and other materials needed by financial institutions, retailers, and law enforcement as the new MCC code is implemented for gun and ammunition stores,” added the senators. “We also ask Treasury, with input from the DOJ, to issue guidance to financial institutions regarding circumstances that should prompt financial firms to file a suspicious activity report about transactions they suspect are related to trafficking in firearms, money laundering proceeds from trafficking in firearms, or other criminal activity.

The senators highlighted that in the majority of mass shootings between 2007 and 2018, the shooter used credit or debit cards to acquire the guns and ammunition used in the attack. Therefore, banks issuing those cards are in a unique position to flag suspicious buying patterns in a way that law enforcement, family members, and retailers cannot.

“We believe that implementation of the new MCC code for gun stores could enable financial institutions to identify and report potentially illegal gun sales to law enforcement—helping reduce gun trafficking, straw purchases, and transactions structured to evade the mandatory multiple sale reports required by firearm retailers,” concluded the senators. “Financial firms are already obligated to report suspicious transactions connected with a range of illegal activities. Implementation of the new MCC code could provide banks with key insight to identify suspicious patterns of firearm and ammunition purchases, which could potentially help law enforcement preempt mass shootings.”

In addition to Senators Markey, Menendez and Warren, Senators Kirsten Gillibrand (D-N.Y.), Dianne Feinstein (D-Calif.), Chris Murphy (D-Conn.), Mazie Hirono (D-Hawaii), Cory Booker (D-N.J.), Bob Casey (D-Pa.), Brian Schatz (D-Hawaii), Richard Blumenthal (D-Conn.), Tammy Baldwin (D-Wis.), Chris Van Hollen (D-Md.), and Ben Ray Luján (D-N.M.) signed on to the letter.
