Can I Buy a Gun in Idaho If I’m Not a Resident?

If you live in another state, you can buy a rifle or shotgun in Idaho from a licensed dealer, but you cannot buy a handgun there. That’s the short answer to buying a gun in Idaho as a non-resident, and it comes from federal law rather than anything Idaho itself imposes. The sale has to satisfy both Idaho law and the law of the state you live in, and you’ll clear a federal background check like anyone else at the counter.

What You Can and Can’t Buy

The Gun Control Act of 1968 bars any federally licensed dealer from selling a handgun to someone who lives outside the dealer’s state. There is no workaround. An Idaho FFL cannot sell you a pistol or revolver if your residence is elsewhere.¹

Long guns work differently. A licensed Idaho dealer can sell you a rifle or shotgun as long as you appear in person for the transfer and the sale complies with both Idaho’s rules and your home state’s. If your state imposes a waiting period, requires a permit, or bans certain features, the Idaho dealer has to honor those rules on your sale.¹

Frames and receivers are their own category. Federal law classifies a frame or receiver as a “firearm,” but not as a rifle or shotgun, so the interstate long-gun exception doesn’t reach them. The ATF’s Form 4473 instructions state plainly that frames and receivers “cannot be transferred to anyone who is not a resident of the State where the transfer is to take place.” A nonresident can’t buy one in Idaho at any age.² The same logic reaches anything else that doesn’t cleanly fit the rifle-or-shotgun definition. Ask the dealer before you commit.

Federal law also lists categories of people who cannot buy a firearm from anyone, anywhere: convicted felons, people under domestic-violence restraining orders, anyone dishonorably discharged, unlawful users of controlled substances, and several other groups. If you fall into one of those categories, the state you’re in doesn’t matter.¹

Your Home State’s Laws Still Apply

Idaho itself imposes very few restrictions beyond the federal floor. No waiting period, no purchase permit, no registration, no cap on how many guns you can buy in one visit. Idaho Code 18-3302 covers concealed carry but adds no residency-based purchase restrictions for long guns.³

The complications come from your home state. Dealers are legally presumed to know the laws of your state and typically consult the ATF’s reference materials before finishing an interstate sale. If California, New York, or your state of residence would restrict the specific rifle or shotgun you’re eyeing, the Idaho dealer has to enforce that restriction. Idaho being permissive doesn’t override anything.¹

Private Sales Are Off the Table

Idaho doesn’t require background checks for private sales between two Idaho residents. That fact traps a lot of nonresidents. Federal law separately prohibits any unlicensed person from selling or transferring a firearm to someone they know or reasonably believe lives in a different state. An Idaho neighbor selling you a rifle out of a garage is committing a federal crime, and so are you if you know you’re not an Idaho resident.¹

The only legal way to complete a private-party purchase across state lines is to route the transfer through a licensed dealer who can run the background check and confirm compliance with both states’ laws. Idaho’s relaxed private-sale rules stop at the state line.

Age at the Counter

Federal law sets the minimum age at 18 for a rifle or shotgun from a licensed dealer and 21 for a handgun. Because nonresidents are limited to long guns anyway, 18 is the number that matters at an Idaho counter. Frames and receivers follow the handgun rule and require 21, but those are off-limits to nonresidents regardless.²

ID and the Background Check

You’ll need a valid government-issued photo ID showing your name, date of birth, and residence address. A driver’s license from your home state is the usual choice. If your photo ID doesn’t carry your current address, federal rules let you supplement it with a second government document that does, such as a vehicle registration.⁴

The dealer uses your ID to determine which state’s laws apply. Handing over an Idaho license while actually living in another state is a federal crime on the Form 4473. Dealers are trained to flag mismatches and may ask for more documents if something looks off.²

The dealer then submits your information to the National Instant Criminal Background Check System and gets one of three answers: proceed, denied, or delayed. Proceed means the sale can happen. Denied stops it. Delayed gives the FBI three business days to finish researching; if those pass without a final answer, the dealer may legally transfer the firearm, though many choose to wait. The three-day rule sits inside the Brady Act and applies to residents and nonresidents alike.⁵

Active-Duty Military Are Treated Differently

If you’re on active duty, your state of residence for firearm-purchase purposes is the state where your permanent duty station is located, not the state on your driver’s license. Stationed in Idaho? You’re an Idaho resident at the counter, which means you can buy handguns as well as long guns.⁶

Bring your military ID and your Permanent Change of Station orders showing an Idaho duty station. That combination satisfies the Brady Act’s identification requirements even if you live off base and your driver’s license was issued somewhere else.⁴

Getting the Gun Home

Buying is only half the trip. The Firearms Owners’ Protection Act shields you during interstate transport if you meet its conditions. The firearm must be unloaded, and neither the gun nor the ammunition can be readily accessible from the passenger compartment. In a vehicle without a separate trunk, both have to be in a locked container. The glove compartment and center console do not qualify.⁷

FOPA protects continuous travel. If your route runs through a state that prohibits the firearm you’re carrying and you stop for an extended stay rather than passing through, you can lose that protection. Plan the states in between, not just the destination.

Carrying in Idaho While You’re There

Idaho allows permitless concealed carry for anyone at least 18 years old, a U.S. citizen or current member of the Armed Forces, and not otherwise prohibited from possessing firearms. The law doesn’t require Idaho residency, so a qualifying visitor can carry concealed without a permit while in the state.⁸

What It Costs If You Get It Wrong

Lying on Form 4473, including about your state of residence, is a federal felony under 18 U.S.C. 922(a)(6) carrying up to 10 years in prison. Filling out the form with false information is itself the crime; you don’t need to walk out with the gun for the charge to stick.⁹

Buying a firearm for someone else who is the actual buyer, a straw purchase, is a separate federal crime under 18 U.S.C. 932 carrying up to 15 years. Penalties climb if the actual recipient is a prohibited person or if the firearm is used in a serious crime.¹⁰

The private-sale prohibition has teeth on both sides. An Idaho resident who transfers a firearm to someone they know lives out of state violates 18 U.S.C. 922(a)(5), and the buyer can be charged too. This is what makes those informal cross-state sales federal crimes no matter how permissive either state’s own laws read.¹
