Where to Find the Serial Number on a Firearm
Quick answer: The serial number is engraved or stamped on the frame or receiver of the firearm — the location varies by manufacturer and type.
Under federal law (Gun Control Act of 1968), all licensed firearm manufacturers must engrave a unique serial number on every firearm produced. Here's where to find it by type:
Handguns (Pistols)
Frame, near trigger guard or grip. Also may be on the slide or barrel.
Revolvers
Frame above the trigger, on the butt of the grip, or on the crane.
Semi-Auto Rifles (AR-15, AK-pattern)
Lower receiver, typically near the magazine well or pistol grip.
Bolt-Action & Lever-Action Rifles
Receiver (the metal housing), often bottom or side.
Shotguns
Receiver, near the trigger group.
Revolvers (Smith & Wesson)
Butt of the grip, cylinder crane, and frame.
If the serial number has been removed, altered, or defaced, do not purchase the firearm. Under 18 U.S.C. § 922(k), it is a federal felony to possess a firearm with an obliterated serial number — even if you did not remove it yourself.
Which Databases Does SafeOrStolen Check for Firearms?
Quick answer: every gun check searches police theft and loss reports from 33 states and Washington, DC, live Ohio law-enforcement records, SafeOrStolen's own theft reports and public web results, and checks the serial for tampering.
All of these are searched at the same time, and the result lists each one, so you know exactly what was checked before money changes hands.

242,839 reports of stolen and lost guns filed with police in 33 states and Washington, DC. Matches show the make, model, state and year of the report.
Serial Number Integrity Check
We validate the serial number itself for obliterated, altered, or placeholder patterns. A defaced serial number is a federal felony under 18 U.S.C. § 922(k) and is a strong signal to walk away.

Legal Risks of Buying a Stolen Firearm
Quick answer: Possession of a stolen firearm is a federal felony even if you unknowingly purchased it. Law enforcement can seize the firearm with no compensation to you.
This is not a minor civil matter. Buying a stolen gun — even unknowingly — creates serious legal exposure under both federal and state law:
- ⚠️
Federal criminal exposure
Under 18 U.S.C. § 922(j), knowingly purchasing, possessing, or transferring a stolen firearm is a federal felony carrying up to 10 years in prison. "Knowingly" is broadly interpreted — if you had reason to know the gun was stolen (low price, seller unwilling to provide paperwork), that can be sufficient.
- ⚠️
State criminal exposure
All 50 states have additional receiving stolen property statutes. Penalties vary but typically include felony charges for firearms.
- ⚠️
Asset seizure with no compensation
Law enforcement can seize a firearm linked to theft records at any time. You have no legal claim to compensation — your money is gone.
- ⚠️
Background check complications
A stolen firearm discovered during a transfer at a licensed dealer (FFL) will result in the transfer being denied and possible investigation of all parties involved.
Who Should Always Run a Gun Serial Check
Quick answer: Anyone buying, accepting, or reselling a used firearm — including private buyers, pawn shops, gun show attendees, estate sale participants, and FFL dealers.
🎯 Private Buyers
Anyone purchasing a used firearm through a private sale on Armslist, Facebook, at a gun show, or from an individual. Private sales in most states have no background check — the serial check is your only protection.
🎯 Gun Show Vendors & Attendees
High volume + cash transactions = elevated risk. Many stolen guns circulate through gun shows precisely because of lighter scrutiny. Run a check on every private transaction.
🎯 FFL Dealers Buying Used Inventory
When buying used firearms from individuals for resale, a serial check provides documented due diligence before you take ownership.
🎯 Estate Sale Participants
Firearms in estates can have complex ownership histories. Verify before purchasing — you have no way to know the history of an inherited firearm.
🎯 Sellers Proving Legitimacy
Sellers can run a check on their own firearm and share the clean result with buyers — increasing buyer confidence and selling price.
Red Flags When Buying a Used Firearm
Quick answer: Never buy if the serial number is missing, altered, or if the seller refuses to allow you to write it down for verification purposes.
- 🚩Serial number is scratched, filed, or otherwise altered — federal felony to possess
- 🚩Seller refuses to provide the serial number or allow you to record it
- 🚩Price is significantly below market value for the model and condition
- 🚩Seller cannot produce original purchase receipt or documentation of transfer
- 🚩Seller is unusually eager to complete the sale quickly, especially in cash
- 🚩Firearm has aftermarket modifications that obscure the original serial number location
- 🚩Seller says they "found it" or received it as payment for a debt
- 🚩No box, accessories, or documentation that would normally accompany a legitimate sale
Sellers: Verify Your Own Firearm First
Quick answer: Run a SafeOrStolen check on your own firearm, get the $1.99 verification certificate, and share its link with buyers so they can see the check for themselves.
Smart sellers use SafeOrStolen to prove legitimacy upfront. Here's why it matters:
- ✓Buyers don't have to take your word for it; the certificate shows the date and what was searched
- ✓A dated record that you checked before the sale, if questions come up later
- ✓Makes your listing stand out from unverified ones
Pawn Shop Firearm Compliance Requirements
Quick answer: Pawn shops are commonly required by state or local law to report the guns they take in to police, and they carry more risk than private buyers when a gun turns out to be stolen. Checking every serial before you accept it, and keeping the record, is basic due diligence.
Pawn shop operators face significant legal exposure when accepting stolen firearms. Unlike private buyers who may unknowingly purchase stolen property, pawn shops are considered sophisticated commercial buyers — courts hold them to a higher standard of due diligence.
