The "Crime Gun Tracing Modernization Act of 2025" mandates the establishment of comprehensive electronic databases for firearm transaction records. Specifically, it requires the National Tracing Center of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) to create and maintain searchable databases of all records related to the importation, production, shipment, receipt, sale, or other disposition of firearms submitted by licensed entities. Licensees are also permitted to provide electronic access to their records or voluntarily relinquish non-electronic records to the ATF after a 10-year period under certain conditions. These databases are designed to be remotely accessible by the National Tracing Center, but access is strictly limited to specific purposes. These include obtaining information for bona fide law enforcement investigations , foreign intelligence, or compliance inspections of active licensees. While searchable by firearm characteristics such as serial number and manufacturer, the databases are explicitly prohibited from being searchable by the personally identifiable information of any individual. Furthermore, the bill mandates biennial audits by the Comptroller General to ensure compliance with these requirements and report findings to Congress.
