To report a lost or stolen gun, call your local police or sheriff’s department right away — use 911 if a theft is still in progress, otherwise the non-emergency line — and give them the firearm’s serial number, make, model, caliber, and the circumstances of the loss. Get the police report number in writing before you hang up. Depending on your state and the type of firearm, you may also have a separate deadline to report to a state agency or to the ATF.
Gather the Firearm’s Details Before You Call
The single most important piece of information is the serial number. Without it, law enforcement cannot enter the firearm into the national stolen guns database, and the odds of recovery drop sharply.
Pull together as much of the following as you can:
- Serial number, usually stamped on the frame or receiver, and often on the original purchase receipt, registration paperwork, or a photo you took of the gun.
- Make and model, meaning the manufacturer name and specific model designation.
- Caliber and type — pistol, revolver, rifle, or shotgun — along with the chambering.
- Distinguishing features such as aftermarket grips, optics, engravings, scratches, or modifications.
You will also need the date you discovered the loss, the approximate time, the location, and how you believe the firearm went missing. If it was taken during a burglary, note what else was stolen and any signs of forced entry. Have your full name, address, and contact information ready.
If You Don’t Have the Serial Number
Many gun owners never wrote it down. If you can’t find a receipt or registration document, contact the dealer where you bought the firearm. Dealers are required to keep sales records and can look up the serial number from the original transaction. If the dealer is out of business, ask your local police department for guidance. The ATF does not assist private citizens with serial number lookups.1Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Report Firearms Theft or Loss
File the Report With Local Law Enforcement
Your local police or sheriff’s department is always the first agency to call, regardless of what state you’re in. For an active break-in or robbery, dial 911. For a discovered loss or a theft you’re reporting after the fact, use the non-emergency line. Some departments also take reports online or at the front desk of a station, but calling first is usually fastest.
File with the agency that has jurisdiction where the theft or loss occurred. If your firearm was stolen from your car while you were traveling and you’re not certain exactly where it happened, report it to the agency where you are.2ATF eRegulations. 27 CFR 478.39a – Reporting Theft or Loss of Firearms If the theft happened out of state, be aware you may still need to satisfy that state’s reporting rules on top of your home state’s.
When you make the report, hand over every detail you gathered. The officer will want the serial number, make, model, caliber, type, circumstances, and your contact information. Before the call ends, ask for the police report number and any written confirmation the agency will give you.3Department of Justice. Commentary for Firearm Theft/Loss Reporting Model Legislation Keep that number somewhere safe. You will need it for follow-up with other agencies, your insurance company, and any future inquiry if the firearm is recovered.
How Your Report Enters the National Database
After the responding agency takes your report, it enters the firearm’s information into the FBI’s National Crime Information Center, or NCIC. The NCIC Stolen Gun File is a computerized index available to every federal, state, and local law enforcement agency in the country, 24 hours a day. Once your gun is in the file, any officer who runs the serial number during a traffic stop, pawn shop check, or investigation gets an immediate hit showing it was reported stolen. The record stays in the system indefinitely until the originating agency clears it, so it does not age out.4Federation of American Scientists. National Crime Information Center (NCIC)
The serial number is the primary search key for that database. A report without one still creates a paper trail for your protection, but the chances of the firearm being identified and returned to you drop sharply.
Check Your State’s Reporting Deadline
There is no federal law requiring private citizens to report a lost or stolen firearm. The obligation comes from state law, and roughly a dozen states plus the District of Columbia currently mandate reporting. Deadlines vary. Some states require you to file within 24 hours of discovering the loss, others give you up to five days. Penalties for missing the deadline range from small fines around $25 on a first offense to $1,000 or more for repeat violations, with some states classifying repeated failures as misdemeanors or even felonies.
Even where reporting is not mandatory, filing is in your interest. When you call to make the initial police report, ask the department whether your state imposes a separate reporting deadline you need to meet.
Federal Reporting: When It Applies to You
For most private gun owners, there is no federal reporting requirement. The ATF explicitly does not accept theft or loss reports from private citizens for standard firearms. Your local police report is enough on the federal side; if the circumstances involve a criminal investigation, local law enforcement can submit a trace request to the ATF’s National Tracing Center on their own.1Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). Report Firearms Theft or Loss
NFA-Registered Firearms Are the Exception
If you own a firearm registered under the National Firearms Act — a suppressor, short-barreled rifle, short-barreled shotgun, or machine gun — federal regulations require you as a private citizen to report the theft or loss to the ATF immediately upon discovery.5eCFR. 27 CFR 479.141 – Stolen or Lost Firearms “Immediately” is the actual word in the regulation. There is no 48-hour or five-day grace period.
Your report to the ATF must include your name and address as the registered owner, the kind of firearm, the serial number, model, caliber, manufacturer, the date and place of the theft or loss, and a complete description of the circumstances.5eCFR. 27 CFR 479.141 – Stolen or Lost Firearms NFA items are tightly tracked through a federal registry, so the ATF already has the item linked to you. Late reports raise questions about whether the firearm was actually stolen or illegally transferred.
File Your Insurance Claim
Once the police report is filed, contact your homeowners or renters insurance company. Most standard policies cover stolen firearms under personal property coverage, but there is a common catch: the typical policy caps theft coverage for firearms at around $2,500 total, regardless of how many guns were taken or their actual value. If your collection is worth more, full replacement coverage generally requires a scheduled endorsement or rider you would have needed to add earlier.
Your insurer will ask for the police report number, a description of each firearm, and proof of ownership or value such as purchase receipts, appraisals, or photographs. File promptly. Some policies have their own reporting deadlines, and delay can complicate the claim. Keep copies of everything you submit.
Why the Report Protects You
A filed report separates you from whatever the firearm is later used for. If your stolen gun turns up at a crime scene, investigators will trace it to the last known owner. A police report showing you reported the theft before the crime occurred is powerful evidence that you had no part in it. Without that report, you may end up explaining to detectives why a gun linked to you was used in a shooting. Even if no charges are filed, being investigated is worth avoiding. An unreported theft can also undermine your credibility if you later need to raise a negligence defense in a civil lawsuit.
What Happens After You Report
Once the report is filed and the serial number is in NCIC, the active investigation shifts to law enforcement. Your job at that point is to stay reachable. Investigators may contact you for more details, especially if the theft was part of a larger burglary or a pattern in your area. Keep organized copies of the police report, any confirmation numbers from state agencies, and your insurance claim paperwork. If you remember additional details later, call the investigating officer and supplement the report.
If Your Firearm Is Recovered
When a stolen firearm is found, law enforcement identifies the owner through the NCIC record and contacts you. Getting it back is not always quick. If the gun is connected to an ongoing criminal case, it will be held as evidence for the duration of that case, which can stretch months or years depending on the charges. Even after the case ends, you will typically need to provide proof of ownership and may need to complete paperwork or pay administrative or storage fees, which vary by jurisdiction, before the firearm is released.
If you are notified that your firearm has been recovered but the agency delays or refuses to return it, you generally have the right to petition a court for its return. The process depends on local and state law, and this is a situation where consulting an attorney familiar with firearms law in your area is worth the cost.
