Once upon a time, in 1977 when I was an MP, one of my jobs was running the computer to do background checks on anyone stopped by a patrol unit or gate. Our computer was, primitively, linked to CCIC (Colorado Crime Information Center) computer which also queried NCIC (National yada yada). So, once upon a time it was NCIC.
You are confusing two different FBI databases.
NCIC is the National Crime Information Center, a database of wanted fugitives, stolen property, missing persons, etc.
NICS is the National Instant Criminal Background Check System, used for background checks on purchasers of firearms. NCIC is only one of the three national databases searched by NICS.
Licensed dealer do not have access to NCIC, only LE.
In Florida we don't use NICS, we have the FDLE Firearms Eligibility System.
Well, yeah you do. Because Florida is a state POC (point of contact) it means licensed dealers do not contact FBI NICS directly, but contact a state agency (your FDLE) who then accesses FBI NICS. (some states are partial POC's, contacting FBI NICS directly for some checks, a state agency for others)
I recommend anyone having an issue with being approved, even just one single time, to get what FDLE calls a UPIN, a Unique Personal Identification Number, although I don't know what the deal is with the SSN not doing that, but some folks don't want to share their SSN.
Yeah, a UPIN as already mentioned above, allows FBI NICS to keep the buyers information open. That UPIN number is issued by the FBI, not Florida.
A SSN is helpul, but often does not prevent delays.
Also, b/r checks run on Sat afternoons always take longer because of all the gun shows going on around the state.
Not unique to Florida btw.
