Each year, more than 40,000 Americans are killed by guns, according to the Gun Violence Archive, and while federal law requires licensed firearm dealers to conduct background checks on all gun buyers in the United States, there are loopholes. Background checks are typically completed in under two minutes and are designed to keep guns out of the hands of convicted felons, domestic abusers, and other Americans otherwise prohibited from gun ownership. All 50 states are subject to these rules, but in much of the country, there are ways around the federal law.

National background check laws only apply to licensed gun dealers, which results in millions of firearms being sold every year by private dealers – including those who sell guns online, at gun shows, or elsewhere without a federal license. According to the Bureau of Alcohol, Tobacco, Firearms, and Explosives, the loophole is exploited by unlicensed dealers to traffic firearms to prohibited buyers. (Here is a look at the states where the most guns are stolen.)

A 2023 poll by the McCourtney Institute for Democracy shows that 86% of American adults support background checks for firearm sales and transfers, and according to a Gallup survey, 56% believe regulations should be stricter than what they currently are. But despite widespread public support, lawmakers in Washington have yet to enact universal background check laws. In the absence of federal legislation, many states have taken action. 

24/7 Wall St. reviewed background check laws in every state by using data from gun violence prevention group Giffords Law Center. Of the 50 states, 15 have universal background check laws. Under these laws, all firearm sales must be conducted through a licensed dealer. In the case of private sellers, they are required to carry out a background check through licensed dealers or law enforcement. An additional six states have not enacted such laws, but require (or will soon require) firearm owners to have a permit – and a background check is required to obtain the permit. (Here is a look at the states with the strictest gun control laws.)

The loophole in the federal background check law remains in 29 states. Gun ownership rates in these states tend to be far higher than they are in the 21 states with universal background checks. Gun violence also tends to be more common in states with the private seller loophole. Of the 15 states with the highest firearm death rate, only two have universal background check laws.

Here are the universal background check laws in every state.

Methodology

24/7 Wall St. reviewed data compiled by the gun violence prevention group Giffords Law Center to identify the background check laws in each state. We also reviewed 2021 firearm mortality data from the Centers for Disease Control and Prevention.  

Supplementary data on the share of households that own a gun came from a 2020 study published by the RAND Corporation, a research and public policy advocacy group. States are ranked by the estimated share of households that owned at least one firearm in 2016, the most recent year of available data.
