(FFL) are required to undertake a NICS background check on prospective buyers before transferring a firearm. The NICS is not intended to be a gun registry, but is a list of persons prohibited from owning or possessing a firearm. By law, upon successfully passing the background check, the buyer's details are to be discarded and a record on NICS of the firearm purchase is not to be made. However as an FFL holder, the seller is required to keep a record of the transaction. Access to NICS is limited to FFL holders. A prospective buyer is required to complete ATF

, after which an FFL seller initiates a NICS background check by phone or computer. Most checks are determined within minutes and if a determination is not obtained within three business days, then the transfer may legally be completed. While background checks under federal law are not required for intrastate firearm transfers between private parties through the Gun show loophole or private sale loophole, federal law states that only FFL-holders may transport a firearm across state lines for the purpose of sale. Sales between two private parties may be conducted without a background check, so long as both the buyer and seller are residents of the state that the transfer is being conducted. Some states require background checks for firearm transfers not covered by the federal system. These states either require gun sales to be processed through an FFL holder, or they may require the buyer to obtain a license or permit from the state. Nearly 30 million NICS background checks were performed in 2023.


Background

Background checks of firearm buyers was discussed as early as the 1930s. The

(FFL). It also created a system for keeping prohibited persons (e.g. a person determined to be prohibited of possessing a weapon due to criminal history or immigration status) from buying guns that relied upon buyers answering a series of "yes/no" questions such as, "Are you a fugitive from justice?". However, sellers, including FFL dealers, were not required to verify the answers. Coordinated efforts to create a national background check system did not materialize until after the assassination attempt on President Ronald Reagan in March 1981. White House press secretary

in 1993. When signed into law in November of that year, the Brady Act included a GCA amendment that created the National Instant Criminal Background Check System (NICS). The Brady Act mandated that FFL dealers run background checks on their buyers. At first, the law applied only to handgun sales, and there was a waiting period (maximum of five days) to accommodate dealers in states that did not already have background check systems in place. Those dealers were to use state law enforcement to run checks until 1998, when the NICS would become operational and come into effect. In 1997, the Supreme Court ruled against the five-day waiting period, but by 1998 the NICS was up and running, administered by the FBI, and applied to all firearms purchases from FFL dealers, including long guns.

(III), and the NICS Index. According to the FBI, checks are usually determined within minutes of initiation. If there is no match in any of the checked databases, the dealer is cleared to proceed with the transfer. Otherwise, the FBI's NICS Section must contact the appropriate judicial and/or law enforcement agencies for more information. Per the Brady Act, the FBI has three business days to make its decision to approve or deny the transfer. If the FFL dealer has not received the decision within that time it may legally proceed with the transaction. If the FBI later determines that the buyer is prohibited, it refers it to the

(ATF) to retrieve the firearm. In 2019, 261,312 federal background checks took longer than three business days. Of those, the FBI referred 2,989 to ATF for retrieval. The FBI stops researching a background check and purges most of the data from its systems at 88 days. This happened 207,421 times in 2019. States may implement their own NICS programs. Such states become the point of contact (POC) between their FFL dealers and the NICS. A few partial-POC states run FFL handgun checks, while the FBI runs long gun checks. FFL dealers in other, non-POC states access the NICS directly through the FBI. Authorized local, state, tribal and federal agencies can update NICS Index data via the NCIC front end, or by electronic batch files. In addition, the NICS Section receives calls, often in emergency situations, from mental health care providers, police departments, and family members requesting placement of individuals into the NICS Index. Documentation justifying entry into the NICS Index must be available to originating agencies. The ATF has designated some states' firearm possession or carry permits/licenses as exempting that person from the NICS background check requirement since ownership of such permits/licenses require a background check.

Firearm denial appeals

A buyer who believes that a NICS denial is erroneous may appeal the decision by either challenging the accuracy of the record used in the evaluation of the denial or claiming that the record used as basis for the denial is invalid or does not pertain to the buyer. The provisions for appeals are outlined in the NICS Regulations at Title 28, Code of Federal Regulations, Part 25.10, and Subsection 103 (f) and (g) and Section 104 of the Brady Handgun Violence Prevention Act of 1993.

rights. The NRA says that "there is significant reason to believe that the number of erroneous denials is far greater than those overturned on appeal" because some people may not appeal erroneous denials. In an operations report in 2014 by the FBI, of a total of 90,895 "deny transactions", 4,411 (about 5%) were overturned after further research by the NICS section. According to the report, "The primary reason for the overturned deny decisions in 2014 was the appellant's fingerprints not matching the fingerprints of the subject of the firearms-disqualifying record. Another chief reason deny decisions are overturned on appeal pertain to criminal history records that do not contain current and accurate information ... In cases where the matches are refuted by fingerprints, the NICS Section may overturn the subject's deny decision and allow the transaction to proceed. However, because the NICS is required to purge all identifying information regarding proceed transactions within 24 hours of notification to the FFL, in many instances, the process must be repeated when the same transferee attempts subsequent firearm purchases and is again matched to the same prohibiting record." The NICS system however also includes a "Voluntary Appeal File" procedure, by which an individual may request that the NICS section retain their identifying information, rather than purging it, to prevent future erroneous denials or delays. Between November 30, 1998 and May 31, 2016, the NICS denied 1,323,172 transactions. The top reasons for denials include: "Convicted of a crime punishable by more than one year or a misdemeanor punishable by more than two years", "Fugitive from Justice", "Misdemeanor Crime of Domestic Violence Conviction" and "Unlawful User/Addicted to a Controlled Substance".
