Concealed carry reciprocity is the set of rules that decide whether the permit you hold at home lets you carry a concealed firearm in another state. There is no national standard. Each state chooses which out-of-state permits it will honor, and those decisions change through legislation and attorney general opinions often enough that a route legal last year may not be legal today. Federal law adds a narrow safe-passage protection for moving a firearm through a state that won’t recognize your permit, but that protection is much thinner than most travelers assume. Getting the details right is the difference between a routine trip and a felony arrest.
How States Decide to Honor Each Other’s Permits
Recognition comes in two forms. Unilateral recognition is a one-way decision: a state chooses on its own to honor permits from some or all other states, usually based on whether the issuing state’s standards clear a minimum set by the recognizing state’s attorney general. Your home state doesn’t have to reciprocate for the arrangement to work in that direction.
Bilateral reciprocity is a formal agreement between two states to honor each other’s permits, typically requiring comparable background-check and training standards on both sides. If one state loosens its rules, the other can terminate the agreement, and permit holders lose their carry privileges when it ends. Both types are documented through state attorneys general, which is where the current status is most reliably confirmed.
The Permitless Carry Trap for Travelers
As of 2025, 29 states allow residents to carry a concealed firearm with no permit at all, a policy usually called constitutional or permitless carry. That figure has roughly doubled in the past decade. Permitless authority almost always stops at the state line. The moment you drive into a state that still requires a license, you need a physical permit to carry legally there.
If you live in a permitless-carry state and never applied for a permit, you have nothing to hand to a reciprocal state. Most permitless-carry states still issue voluntary permits precisely for this reason. Getting one before you leave is the simplest way to keep carry privileges when you cross a border. Without the card, reciprocity has nothing to recognize.
Federal Safe Passage Under 18 U.S.C. § 926A
When your route runs through a state that won’t honor your permit, the Firearm Owners Protection Act of 1986 gives you a fallback. Under 18 U.S.C. § 926A, you may transport a firearm through such a state if you can legally possess it at both the origin and the destination, the firearm is unloaded, and neither the firearm nor any ammunition is readily accessible from the passenger compartment. A conventional trunk satisfies the accessibility requirement on its own. In vehicles without a separate trunk, such as SUVs, hatchbacks, and minivans, the firearm and ammunition have to be in a locked container other than the glove compartment or console.1Office of the Law Revision Counsel. 18 USC 926A – Interstate Transportation of Firearms
Safe passage covers continuous travel. Fueling stops and brief breaks generally count as part of the trip. An overnight hotel stay, a sightseeing detour, or any extended stop can strip you of the protection and leave you subject to whatever the state’s own law says.
The Third Circuit made the limits clear in the 2005 Revell case. Gregg Revell, a Utah resident traveling by air, had a flight delay force him to retrieve his checked luggage and stay overnight near Newark. When he tried to recheck the bag the next morning, he was arrested under New Jersey law. The court held that § 926A did not protect him because the statute addresses vehicular transport and, once he had his luggage at the hotel, the firearm was readily accessible to him.2United States Court of Appeals for the Third Circuit. Revell v. Port Authority of New York and New Jersey
One more point about § 926A that people misread: violating its storage conditions is not itself a federal crime. The statute is a defense against state prosecution. Fail its conditions and you lose the defense, and the state where you were stopped charges you under its own firearms law. In New Jersey or New York, that can mean years in prison for unlicensed handgun possession.
Flying With a Firearm
Air travel replaces the road-transport rules with TSA regulations for the airport portion of the trip. Firearms must be unloaded and packed in a locked, hard-sided container in checked baggage, declared to the airline at check-in. Ammunition has to be in its original box or a container designed for it. Firearms are never allowed in carry-on bags.3Transportation Security Administration. Firearms – What Can I Bring
The Revell situation is the reason to think carefully about connections. A canceled or rerouted flight can force you to claim luggage in a jurisdiction where the firearm inside is illegal, and safe-passage protection is unlikely to reach you at that point. There is no clean legal fix, which is why some travelers avoid flying with firearms through restrictive connecting airports at all.
Local Rules That Still Apply in Reciprocal States
A recognized permit gets you the right to carry in another state. It does not exempt you from that state’s specific carry rules, and this is where most out-of-state travelers get into trouble.
Duty to Inform
Roughly a dozen states require you to immediately tell a law enforcement officer that you are armed during any encounter, including a traffic stop. The duty exists whether or not the officer asks. Failure to disclose can be a criminal offense and, in some states, grounds for permit suspension. Keeping your hands visible and telling the officer early is the safest practice in any state.
Magazine Capacity
Fourteen states and the District of Columbia limit magazine capacity, most commonly to 10 rounds, with a few setting the ceiling at 15 or 20. A 15- or 17-round magazine that is standard equipment at home can trigger confiscation, criminal charges, or both if you cross into a restricted state. Swap in compliant magazines before the border if your route goes through one.
Alcohol
Most states restrict carrying while under the influence, and a handful ban any drinking at all while armed. The definition of intoxicated varies: some states use their DUI threshold of 0.08 BAC, some leave it undefined, and a few enforce zero tolerance. If you plan to have a drink with dinner, secure the firearm in your hotel or vehicle first.
At least 14 states also prohibit carrying in establishments that primarily serve alcohol, sometimes called the 51 percent rule because it targets businesses that make most of their revenue from liquor sales. The prohibition applies whether or not you personally are drinking. Restaurants that serve alcohol may be treated differently from dedicated bars depending on the state.
Private Property Signs
Private businesses can prohibit firearms by posting signs. The legal effect varies sharply: in some states, ignoring a posted “no firearms” sign is a criminal offense on its own; in others, the sign has no independent force, and only refusing to leave when asked becomes trespassing. Because researching every state’s signage rule mid-trip isn’t realistic, the practical rule is to respect posted signs everywhere.
Prohibited Locations
Every state maintains its own list of places off-limits even to permit holders. Schools, courthouses, government buildings, polling places, hospitals, and houses of worship appear on many of these lists, with the specifics differing. A location that is fine at home can be a felony next door. Checking the destination state’s prohibited-locations list is as important as confirming reciprocity.
Federal Zones No Permit Covers
No state permit and no reciprocity agreement authorizes you to carry into certain federal properties, and these rules apply uniformly nationwide.
Under 18 U.S.C. § 930, possessing a firearm in a federal facility, meaning a building owned or leased by the federal government where federal employees regularly work, is a crime. Federal courthouses are treated more strictly, with the prohibition extending to courtrooms, chambers, jury rooms, and adjoining corridors. Signs must be posted at public entrances, though actual knowledge of the prohibition can support a conviction without one.4Office of the Law Revision Counsel. 18 U.S. Code 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
The Postal Service ban is one of the strictest and catches travelers off guard. Under 39 C.F.R. § 232.1, no one may carry a firearm openly or concealed, or store one, on any real property under Postal Service control, and that includes the parking lot.5eCFR. 39 CFR 232.1 – Conduct on Postal Property
National parks follow the law of the state they sit in. If your permit is recognized there, you may carry in the park itself, but federal buildings within the park, including visitor centers, ranger stations, and fee-collection buildings, remain off-limits under § 930. Discharging a firearm in a park is prohibited except where hunting is specifically authorized.6National Park Service. Firearms in National Parks
Self-Defense Law Changes at the State Line
Carrying legally is one question. When you may actually use the firearm is another, and the answer also shifts across borders. In stand-your-ground states, you generally have no obligation to retreat before using deadly force in self-defense, as long as you are somewhere you have a right to be and are not engaged in unlawful activity. In duty-to-retreat states, you must attempt a safe retreat before using deadly force, usually with an exception for your own home under the castle doctrine. The gap between those frameworks is the gap between a justified shooting and a murder charge.
Some states extend castle-doctrine protection to occupied vehicles, treating your car or RV like your home for self-defense purposes. Others limit the doctrine to a fixed dwelling. Whether you can legally defend yourself with deadly force in an RV during a campground break-in depends entirely on which state that campground is in.
Planning a Trip Across Multiple States
The foundation of an interstate trip with a firearm is mapping the route and checking reciprocity for every state you’ll enter, including states you’re only passing through. A single gap means you either detour, store the firearm to comply with § 926A, or accept the risk of prosecution.
When gaps exist, obtaining a non-resident permit from a state with broad recognition is the standard workaround. A handful of states are popular for this because their non-resident permits are honored widely. Applications typically require fingerprints, a firearm safety course, and a background check. Fees generally fall in the $60 to $120 range, and permits are usually valid for five to seven years. Processing runs from a few weeks in shall-issue states to several months where the issuing agency has more discretion, so apply well in advance. A non-resident permit may carry different restrictions than a resident permit from the same state, so read the terms.
Reciprocity agreements shift often. A state that honored your permit last year may not honor it now. The attorney general’s office in each state along your route is the most reliable source. Third-party apps and websites that haven’t been updated recently are a common way travelers get caught out. Save the current listings before you go, and check again if your departure slips by more than a few weeks.
