If you buy a gun from a licensed dealer, yes: federal law requires a background check every single time, with no exceptions for the type of firearm or how many you’ve bought before. If you buy from a private individual who isn’t a licensed dealer, federal law generally does not require a background check, though more than a dozen states have passed their own laws that do. So whether you need a background check to buy a gun comes down to who is selling it and what state you’re in.
Buying From a Licensed Dealer
Any business holding a Federal Firearms License (FFL) must run a background check before handing you a firearm. That includes gun stores, pawn shops, and sporting goods retailers. The requirement comes from the Brady Handgun Violence Prevention Act, which created the National Instant Criminal Background Check System (NICS) in 1993.1Federal Bureau of Investigation. About NICS
The dealer submits your information to NICS, which checks it against criminal history, mental health, and other disqualifying records. You can’t take the firearm home until NICS clears the sale or a specific waiting period expires. This applies to handguns, rifles, and shotguns alike, and it applies at gun shows too when the seller is a licensed dealer.2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts
NICS returns one of three answers: proceed, denied, or delayed. If it’s delayed, the FBI has three business days to finish investigating. If those three days pass with no final answer, federal law allows (but doesn’t require) the dealer to complete the sale. Some dealers refuse to do default-proceed transfers, and some states have eliminated the option entirely.1Federal Bureau of Investigation. About NICS
Private Sales Between Individuals
Federal law does not require a background check when an unlicensed person sells a firearm to another unlicensed person who lives in the same state.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts This is what people sometimes call the “private sale exception” or the “gun show loophole” — a phrase that traces back to gun shows, where licensed dealers must run checks but private sellers at the same event historically have not.
The exception has real limits. It is a federal crime to sell a firearm to someone you know or have reasonable cause to believe cannot legally have one.4Bureau of Alcohol, Tobacco, Firearms and Explosives. Do I Need a License to Buy and Sell Firearms Guide Private sellers also can’t sell to a buyer who lives in a different state. And states can, and do, layer their own requirements on top of federal law.
States That Require Checks on Private Sales
More than a dozen states and the District of Columbia have universal background check laws. In those states, private sales must be routed through a licensed dealer, who runs the NICS check and processes the paperwork. Buyers usually pay the dealer a transfer fee, commonly in the $25 to $50 range, though fees aren’t federally regulated. Some of these states carve out exceptions for transfers between immediate family members, but the specifics vary by state.
Other Situations Where No Federal Check Is Required
Qualifying State Permits
If you hold a state-issued permit (such as certain concealed carry licenses) that the ATF recognizes as a NICS alternative, your dealer may not need to run a point-of-sale check. The state must have run a NICS check before issuing the permit, and the permit must have been issued or renewed within the past five years. Even so-called “lifetime” permits only qualify as NICS alternatives for five years from their issue date.5Bureau of Alcohol, Tobacco, Firearms and Explosives. ATF 2025L-01 NICS-Brady Open Letter The ATF publishes the current list of qualifying permits.6Bureau of Alcohol, Tobacco, Firearms and Explosives. Brady Permit Chart
Antique Firearms
Federal firearms laws don’t apply to antiques at all. Under 18 U.S.C. § 921, “firearm” excludes antiques, so no background check, no Form 4473, and no requirement to buy through an FFL.7Office of the Law Revision Counsel. 18 U.S. Code 921 – Definitions An antique is a firearm made in or before 1898, or a replica that doesn’t use modern ammunition. Muzzle-loading black powder guns qualify too, as long as they can’t be readily converted to fire modern cartridges.
Gifts
Giving a firearm to a family member or friend who lives in your state does not require a federal background check, assuming your state doesn’t have a universal check law. You still can’t give a firearm to anyone you know or reasonably believe is prohibited from having one. And if the recipient lives in another state, the gift has to go through an FFL in their state, where they’ll clear a background check before taking possession.
Buying From Out of State
Interstate purchases always trigger a check. Federal law bars unlicensed individuals from transferring a firearm directly to someone they know lives in another state.3Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Licensed dealers face limits too: an FFL cannot sell a handgun in person to a buyer from another state. The gun has to be shipped to an FFL in the buyer’s home state, which then runs the NICS check and completes the transfer.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Interstate Controls – ATF Ruling 2010-1 Rifles and shotguns are the exception: an FFL can sell one to an out-of-state buyer in person, provided the sale complies with the laws of both states.
Enhanced Checks for Buyers Under 21
If you’re between 18 and 20 years old, the check is more involved. The Bipartisan Safer Communities Act of 2022 requires the FBI to contact three additional sources in your state: the state criminal history or juvenile justice repository, the state custodian of mental health adjudication records, and local law enforcement.9National Archives. Bipartisan Safer Communities Act of 2022 – Implementation
If those contacts turn up a potentially disqualifying juvenile record, the default-proceed window stretches from three business days to 10.10Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts – Section 922(t)(1)(C) For buyers 21 and older, the standard three-day rule still applies.
Who Can’t Pass a Background Check
Federal law under 18 U.S.C. § 922(g) bars several categories of people from buying or possessing firearms. You are prohibited if you:
- Have a felony conviction, meaning any crime punishable by more than a year in prison, regardless of the sentence actually served.
- Are a fugitive from justice.
- Use or are addicted to controlled substances.
- Have been involuntarily committed to a mental institution or adjudicated as mentally unfit.
- Are unlawfully present in the United States, or, with limited exceptions, are in the country on a nonimmigrant visa.
- Were dishonorably discharged from the military.
- Have renounced U.S. citizenship.
- Are subject to a qualifying domestic violence restraining order.
- Have been convicted of a misdemeanor crime of domestic violence.
These categories apply nationwide.2Office of the Law Revision Counsel. 18 U.S. Code 922 – Unlawful Acts Some states add their own disqualifiers on top.
If Your Check Is Denied
A denial doesn’t always mean you’re actually prohibited. Misidentification is common if you share a name or birthdate with someone who has a disqualifying record. You can challenge a denial by submitting a request through the FBI’s electronic system at edo.cjis.gov or by mail to the NICS Section in Clarksburg, West Virginia. You’ll need the NICS Transaction Number from your denied check, which the dealer can provide. The FBI must issue a final decision within 60 calendar days.11Federal Bureau of Investigation. Challenges / Appeals – Requesting Reason for and/or Challenging a NICS-Related Denial Fingerprints aren’t required with your challenge, but including them speeds things up because they’re the most reliable way to rule out a mismatched identity.
Only denials can be formally appealed. If your check is still in “Delayed” status, you have to wait for a final denial before challenging it.
The Penalties for Lying or Buying for Someone Else
Answering falsely on Form 4473 is a federal felony carrying up to 10 years in prison, and it applies to any false statement, not just the eligibility questions.12Bureau of Alcohol, Tobacco, Firearms and Explosives. Federal Prosecutors Aggressively Pursuing Those Who Lie in Connection With Firearm Transactions
Straw purchasing (buying a firearm on behalf of someone who can’t legally buy one themselves) carries even stiffer penalties. Under 18 U.S.C. § 932, a straw purchase conviction can bring up to 15 years in federal prison. If the buyer knew or had reason to believe the firearm would be used in a violent felony, an act of terrorism, or a drug trafficking crime, the maximum jumps to 25 years.13Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms A conviction on either charge permanently strips you of the right to own firearms.
