What is ATF eTrace?
The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) operates eTrace — an internet-based firearms tracing system used by over 8,000 law enforcement agencies across 46 countries. When a firearm is recovered at a crime scene, law enforcement uses eTrace to trace the gun's chain of custody from manufacturer to distributor to the first retail purchaser.
Here's the critical limitation: eTrace is not available to civilians. Only law enforcement agencies with approved access can submit trace requests. If you're a private buyer looking to verify a firearm before purchase, you cannot access eTrace directly.
SafeOrStolen cannot query eTrace either, and we won't pretend otherwise. What we do is check the serial number against the HotGunz national stolen-firearms registry (32,000+ user-reported records) and analyze it for signs of alteration or obliteration. That's a useful first filter for a private sale — not a substitute for a law enforcement check.

What SafeOrStolen Actually Checks
We'd rather be accurate than impressive. A firearm check on SafeOrStolen does exactly two things:
- HotGunz National Stolen-Firearms Registry — A free public registry of 32,000+ firearms reported stolen by owners and theft victims, nationwide
- Serial Number Integrity Analysis — We analyze the serial itself for obliterated, altered, or placeholder patterns — a defaced serial is a federal felony under 18 U.S.C. § 922(k)
We do not query ATF eTrace, federal law-enforcement systems, or state police systems. Those are closed to consumer services by law. For a definitive answer, ask your local police non-emergency line to run the serial through federal law-enforcement systems — and if you're buying through an FFL, dealers have been able to voluntarily query the federal law-enforcement systems Stolen Gun File since August 2025.
Does the ATF Keep a Gun Registry?
No. Federal law (the Firearm Owners' Protection Act of 1986) explicitly prohibits the ATF from establishing a national firearms registry. The ATF cannot maintain a searchable database of gun owners or gun sales. Instead, ATF traces work by sequentially contacting manufacturers, distributors, and dealers — a manual process that can take days or weeks.
For consumers, the practical question isn't where a gun came from — it's whether it's been reported stolen. SafeOrStolen answers a narrow version of that question instantly by checking the HotGunz registry, then points you to the police check that answers it completely.
