If the licensee receives a “denied” response at any time prior to the transfer of the firearm, the licensee may not transfer the firearm.
If the FBI provides a “denied” response after the third business day, and the firearm has already been transferred, the licensee should notify the NICS Section by phone at 1-877-FBI-NICS (324-6427) or by email at nics_upeg@fbi.gov.
