Serial Number Lookup
Enter a firearm's serial number to estimate the year it was made. Every result cites the published manufacturer chart it came from — we show the threshold serial the factory documented, so you can check the reasoning yourself.
documented gap
This maker’s published tables are documented as imprecise
Winchester serial tables give thresholds, not dates, and the community assessment is blunt — "Most of the numbers you will find online are erroneous (including the PDF on 'Winchesters' website)", with tables that "can be off as much as 3-5 years". Treat any single year as an estimate with that spread attached.
Why two sources give two years for this maker →
How this works. We transcribe the serial-number-to-year charts that
manufacturers publish themselves, keep the documented threshold serial for each year, and
find the latest threshold at or below your number. Nothing is inferred or interpolated —
if a serial falls outside the published ranges, we say so instead of producing a number.

Frequently asked
Is there a free database of gun serial numbers?
Not one that reveals history. Stolen-gun records live in the FBI's NCIC database, which only law enforcement can query, and ATF traces run through eTrace, also law-enforcement only. What is public is the manufacturer's own production chart — which is what this tool uses, and it dates the gun, not identifies an owner.

Why do you show the threshold serial?
So you can verify the answer. Manufacturers publish "first serial shipped that year", so a result is only as precise as the gap between two published thresholds. Showing the threshold makes that precision visible instead of hiding it behind a confident-looking year.

When the lookup can't answer
A serial lookup fails for a handful of distinct reasons, and they need different fixes. Each one below is a page that explains what happened and what to check — written from the manufacturer's published chart, with the reasoning shown.
- Serial has no prefix
- There is no serial number
- Fewer digits than the chart
- Not in the published charts
- Serial is worn or partly readable
- Non-Latin or re-stamped serial
- Make not covered yet

Marks Winchester guns may carry
The serial gives you the year where a chart was published. The proof and inspection marks are the other half: what the gun was tested for, where, and under whose law. These are the ones that turn up on this maker's guns — each with its source class, and each stating what it does not tell you.
