Make Code if Manufacturer and Country Both Unknown

If a firearm has a distinct point(s) of identification or is connected with a major criminal investigation, and neither the make of the gun nor the country where it was manufactured is known, a gun record can be entered in NCIC provided the gun has a serial number. Place the code ZZZ in the MAK Field and “MAK UNKN” as the first item in the MIS Field and note the distinct point(s) of identification or connection to major criminal investigation in the MIS Field. If neither of the two conditions noted above are present, the firearm should not be entered in NCIC even though it does have a serial number. Recovered gun entries containing MAK/ZZZ will be rejected because data cannot be entered in the MIS field of these records.
