Whether a private gun sale needs a background check depends on the state. 17 jurisdictions on this page require one for at least some private sales, usually by running the transfer through a licensed dealer or a permit system. The 30 other states listed don't. In every state, federal law bars selling to someone you know or have reason to believe is prohibited, and a sale to a resident of another state has to go through a dealer.
One thing no background check does: tell you whether the gun was reported stolen. It screens the buyer, not the serial number. Check the serial yourself before money changes hands.

This page is about sales between two people. When you buy from a licensed dealer, the dealer always runs a background check.
Some states cover every gun, some only handguns, and several exempt transfers between close family.
No sales to prohibited people, no direct sales across state lines, and no guns with altered serials, under 18 U.S.C. § 922(k).
In these 17 jurisdictions, at least some private sales need a background check. Read the scope on each: some cover only handguns, and family exemptions differ.
State law in these 30 states doesn't require a background check on a sale between two residents. Federal law still applies to every sale, and the buyer and seller carry the checking themselves: ID, proof of residence, a bill of sale and a serial check.
It depends on your state. 17 jurisdictions on this page, including California, Colorado, Illinois, New York, Pennsylvania (handguns), Washington and the District of Columbia, require a background check on at least some private sales, usually by doing the transfer through a licensed dealer or a permit system. The 30 other states listed here have no state requirement. Federal law still bars selling to anyone you know or have reason to believe can't legally have a gun.
Not directly. Under federal law, a private seller can't transfer a gun straight to a resident of another state. The sale has to go through a licensed dealer in the buyer's home state, who runs the background check and follows that state's rules. Limited exceptions exist, such as guns passed down by will, so ask a dealer before you assume one applies.
No. A background check screens the buyer, to see whether they can legally have a gun. It doesn't search whether that serial number was reported stolen. Check the serial separately on SafeOrStolen (safeorstolen.com/state-firearm-transfer-laws), which searches more than 220,000 police theft and loss reports from 33 states and Washington, DC, live Ohio records and owner reports. Since August 2025, dealers can also voluntarily check the FBI’s stolen-gun file.
Several states that require checks exempt transfers between immediate family members, including Colorado, Nevada, Oregon and Vermont, while Connecticut, New Jersey and New York have their own narrower family exemptions. Each state defines "immediate family" its own way, so a transfer exempt in one state may not be in another. Confirm the current rule with your state before you rely on it.
Federal law still applies to every sale. Ask to see the buyer's ID and confirm they live in your state. Write a bill of sale with the date, price, make, model, serial number and both names, and each keep a copy. If you're the buyer, check the serial before you pay. Many sellers choose to use a dealer anyway for the record it creates.
Michigan, Minnesota, New Mexico and Virginia are not listed here because we did not have confirmed current information for them when the page was published. Their absence does not mean any particular rule applies. Check with that state's police or attorney general, or ask a licensed dealer, before a private sale there.
This page is general information, not legal advice. The state lists reflect the law as of September 10, 2026, and transfer laws, exemptions and permit systems change. Michigan, Minnesota, New Mexico and Virginia aren't listed because we did not have confirmed current information for them; that doesn't mean any particular rule applies there. Check current requirements with your state, a licensed dealer or a lawyer before you complete a sale.
