You can legally buy a gun from a private party in Arizona without a background check, a permit, or any state paperwork, as long as both you and the seller are Arizona residents, neither of you is legally prohibited from having a firearm, and the gun itself isn’t otherwise restricted. Arizona puts the responsibility for a lawful sale on the two people involved rather than on a government system, which means the rules that do apply — federal age limits, prohibited possessor categories, and the ban on interstate private sales — sit squarely on you.
What Arizona Requires From a Private Buyer
Nothing, on paper. Arizona does not require a background check, permit, or registration for a private firearm sale, and state law bars cities and counties from adding their own rules or maintaining databases of firearm owners and buyers.1Arizona Legislature. Arizona Code 13-3108 – Firearms Regulated by State; State Preemption The same framework covers sales in a living room, a parking lot, or a gun show: if the person selling to you is a private individual rather than a licensed dealer, no background check is required.
What Arizona does require is that you actually be eligible to possess the firearm. The absence of a check doesn’t change the underlying law — it just means no system is going to catch a problem before the sale.
How Old You Have to Be
In a private sale in Arizona, you can buy any firearm, including a handgun, at 18. The federal rule that raises the handgun age to 21 applies only to purchases from licensed dealers, and Arizona doesn’t add a stricter state age.2Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Federal law still prohibits transferring a handgun to anyone under 18.
If you are under 18, a private seller cannot sell or give you a firearm without written consent from your parent or legal guardian. Doing so is a Class 6 felony in Arizona.3Arizona Legislature. Arizona Code 13-3109 – Sale or Gift of Firearm to Minor Even with that consent, you still have to be old enough under federal law to possess the specific firearm.
Who Is Barred From Buying
Federal law prohibits several categories of people from receiving or possessing firearms. If any of these apply to you, it is a federal crime to buy the gun, whether or not a background check runs:4Bureau of Alcohol, Tobacco, Firearms and Explosives. Identify Prohibited Persons
- Anyone convicted of a crime punishable by more than one year in prison
- Anyone under indictment for such a crime
- Fugitives from justice
- Anyone who unlawfully uses or is addicted to a controlled substance
- Anyone a court has found mentally defective or who has been committed to a mental institution
- Anyone in the country unlawfully, or, with limited exceptions, admitted on a nonimmigrant visa
- Anyone dishonorably discharged from the military
- Anyone who has renounced U.S. citizenship
- Anyone subject to a qualifying domestic violence restraining order protecting an intimate partner or child
- Anyone convicted of a misdemeanor crime of domestic violence
Arizona’s “prohibited possessor” definition largely tracks the federal list. The private sale doesn’t sanitize any of this — possession itself is the crime.
Buying on Someone Else’s Behalf
If you can pass a background check but you’re buying the gun for someone who can’t, or for someone who wants to stay off the paperwork, that’s a straw purchase. Federal law treats it as a serious crime punishable by up to 15 years in prison, and up to 25 years if the firearm is intended for use in a felony, terrorism, or drug trafficking.5Office of the Law Revision Counsel. 18 USC 932 – Straw Purchasing of Firearms The rule applies to private sales too, not just dealer purchases.
Checking the Seller and the Gun
Arizona doesn’t require you to verify anything about the seller, but a few basic checks protect you. Ask to see a valid Arizona ID to confirm the seller is a state resident. Get the make, model, caliber, and serial number of the firearm, and look at the serial number carefully — if it appears altered or removed, walk away.
Buying a firearm you know or have reason to believe is stolen is a Class 6 felony under Arizona law, and theft of a firearm carries the same classification regardless of the gun’s value.6Arizona Legislature. Arizona Code 13-1802 – Theft; Classification; Definitions A price that seems unusually low, a seller who won’t produce ID, or a tampered serial number are all reasons to stop the transaction. Some local law enforcement agencies will run a serial number to check whether a firearm has been reported stolen, though not every agency offers this to private citizens.
You Cannot Buy Privately From an Out-of-State Seller
Arizona’s private-sale rules only apply when both parties are Arizona residents. Federal law prohibits a private individual from selling a firearm directly to someone who lives in another state.7Congress.gov. Gun Control – Straw Purchase and Gun Trafficking Provisions in P.L. 117-159 – Section: GCA Interstate Transfer Prohibitions If the seller’s license shows a California or Nevada address, or you’re the one who lives out of state, the deal has to run through a licensed dealer in the buyer’s home state, with the standard federal paperwork and background check. This trips up people in border areas like Yuma and Lake Havasu City, where cross-border shopping feels routine.
Running the Sale Through a Dealer Anyway
Arizona doesn’t require it, but you or the seller can ask to route the sale through a licensed dealer. It’s the only way to get an official confirmation through the National Instant Criminal Background Check System that the transaction is clean, and it’s worth considering when you’re dealing with a stranger. The process mirrors a normal retail sale:8Bureau of Alcohol, Tobacco, Firearms and Explosives. Facilitating Private Sales – A Federal Firearms Licensee Guide
- You fill out ATF Form 4473, the standard federal transfer form.
- The dealer runs a NICS check.
- If you’re approved, the dealer logs the firearm in from the seller and out to you.
- If you’re denied, the sale cannot proceed. If the seller had already left the gun with the dealer, the dealer has to run a check on the seller before returning it.
- If the check is delayed, the seller can wait or leave the gun with the dealer pending the result.
Fees in Arizona typically run from about $25 to $75, though prices vary and not every shop handles private transfers. Call ahead.
Getting a Bill of Sale
Arizona doesn’t require a written record, but getting one is worth the ten minutes it takes. If the firearm is ever tied to a crime, a bill of sale showing the date you bought it and who sold it to you is the cleanest evidence that the gun wasn’t yours at the time.
A useful bill of sale includes the date, both parties’ full names and addresses, driver’s license numbers, a description of the firearm with make, model, caliber, and serial number, the sale price, and a statement from the seller (and one from you) about legal eligibility. Both parties sign, both keep a copy. The document has no independent legal force in Arizona, but the paper trail can matter later.
