You do not need to register your firearm in Washington State. There is no state gun registry, no form that asks you to list what you own, and no agency that keeps a master list tying serial numbers to owners. Whether you have one shotgun or a full safe, the state does not require you to tell anyone about it.
The picture gets more layered when you buy, sell, or transfer a gun. Some transactions create records that sit with law enforcement and the Department of Licensing, and those records can look, from the outside, like a form of registration. They aren’t — but knowing when they get created keeps the “no registration” answer from being misleading.
What Washington Requires Instead of Registration
Nearly every firearm sale or transfer in Washington, including private sales between two individuals, has to go through a federally licensed dealer.1Washington State Legislature. Washington Code 9.41.113 – Transfer, Sale, or Delivery of Pistols The dealer runs a background check and both parties fill out federal ATF Form 4473.
For pistols and firearms Washington classifies as “semiautomatic assault rifles,” the dealer also completes a state transfer application. It captures the buyer’s name, address, date of birth, driver’s license number, and the make, model, caliber, and serial number of the firearm. Copies go to the local police chief or county sheriff and to the Washington Department of Licensing, which then runs annual eligibility checks on those owners to confirm they can still legally possess firearms.1Washington State Legislature. Washington Code 9.41.113 – Transfer, Sale, or Delivery of Pistols
That’s the closest thing Washington has to firearm registration. You never sign up for a registry. But if you buy a pistol or a semiautomatic rifle through a dealer, the state ends up with a record of the purchase.
Semiautomatic Assault Rifle Is Broader Than It Sounds
Washington defines a “semiautomatic assault rifle” as any rifle that fires one round per trigger pull and uses energy from the fired cartridge to load the next round. That definition covers common sporting and hunting rifles like the Ruger 10/22, not only military-style platforms. The exceptions are antique firearms, permanently inoperable firearms, and rifles operated manually by bolt, pump, lever, or slide action.2Washington State Legislature. RCW 9.41.010 – Definitions
So if you pick up a .22 semi-auto plinker at a Washington dealer, the enhanced record goes to the sheriff and the Department of Licensing just as it would for a handgun.
Transfers That Don’t Create a State Record
Washington exempts specific transfers from the dealer requirement.3Washington State Legislature. RCW 9.41.113 – Firearm Sales or Transfers – Background Checks Because these transfers skip the dealer, they also skip the state paperwork.
- Genuine gifts and loans between immediate family: spouses, domestic partners, parents, children, siblings, grandparents, grandchildren, nieces, nephews, first cousins, aunts, and uncles.
- Antique firearms that qualify as antiques under state law.
- Inheritance of a firearm other than a pistol when the previous owner dies. An inherited pistol is different: within 60 days, you must either transfer it through a dealer or contact the Department of Licensing to report that you intend to keep it.
The recipient still has to be legally eligible to possess a firearm. Giving a gun to a prohibited person is a federal crime no matter what state exemption applies.
Do I Have to Register Guns When I Move to Washington?
No. If you relocate to Washington with firearms you already legally own, there is nothing to file, no agency to notify, and no deadline that starts running when you cross the state line.4Office of the Attorney General. Firearms FAQ Your existing guns stay unregistered because Washington doesn’t register guns.
Two boundaries matter for new residents, though, and neither one is about registration.
First, Washington prohibits importing large-capacity magazines (those accepting more than 10 rounds) and firearms classified as assault weapons. Under state law, “importing” means bringing the item from outside Washington to inside Washington, and moving here with your own belongings counts. The only carve-out is for someone who temporarily left the state and returns with the same items, which doesn’t help a first-time resident.4Office of the Attorney General. Firearms FAQ People who already lived in Washington when the bans took effect and owned the items beforehand can keep possessing them, but new arrivals cannot bring them in. Violating the assault weapons ban is a gross misdemeanor.5Washington State Legislature. RCW 9.41.390 – Assault Weapons – Manufacturing, Importing
Second, if you carry a concealed pistol, you need a Washington Concealed Pistol License once you become a resident. Out-of-state permits are not honored.4Office of the Attorney General. Firearms FAQ That’s a carry license, not a registration of the pistol itself.
Non-Citizens Need a License to Possess
Washington does require a license, though not a registration, from one group of gun owners. Non-citizens who are not lawful permanent residents must obtain an alien firearm license from the Department of Licensing before possessing any firearm in the state. Possessing a firearm without that license is a Class C felony.6Justia. Washington Revised Code RCW 9.41.170 – Aliens License to Carry Firearms – Exception
The alien firearm license attaches to the person, not to specific guns, so it still isn’t a firearm registry. But it’s the one situation where possessing a gun in Washington requires paperwork on the front end rather than at the point of transfer.
Can a City or County Require Registration?
No. Washington fully preempts local firearm regulation. State law occupies the entire field, including registration, licensing, possession, purchase, sale, transfer, transportation, and ammunition.7Washington State Legislature. RCW 9.41.290 – State Preemption Cities and counties cannot create a local registration scheme, add extra transfer rules, or impose firearm requirements that go beyond state law. Any local ordinance that tries is automatically invalid.
The practical upshot: if you comply with the state rules, you are compliant everywhere in Washington. There is no city where you suddenly owe a registration form, and no county that can demand one.
