National Instant Criminal Background Check System (NICS) Data Integrity Act of 2023

This bill requires the National Instant Criminal Background Check System (NICS) to retain records related to firearm transfers for as long as needed to determine if the transfer violates federal or state law. If a background check remains unresolved after 30 days, the system must notify the person in writing and allow them to submit corrections to their records. It mandates that NICS search specific databases, including the National Data Exchange, NICS Index, and crime information centers, when checking eligibility. The bill directly affects individuals undergoing firearm background checks whose records trigger unresolved flags, ensuring clearer record handling and correction opportunities.
