Enter your Browning A5 serial number to estimate the production year, identify Belgian FN, Remington, or Miroku manufacture, and learn the likely model family including Sweet Sixteen, Light Twelve, Magnum, and standard Auto-5 shotguns.
Enter the complete marking; spaces are allowed. A number alone cannot establish a year or maker. Repeated codes, conflicting ranges and unsupported formats need individual verification.
Full guide and charts: Auto-5 serial number lookup and date chart.
Compare the complete marking with the reference for your model, especially when a date code repeats or a result is uncertain.
This tool interprets published collector references, not factory records for an individual firearm. It keeps conflicting early dates visible and does not infer a maker from an unprefixed number. The model letter matters: an 8 code is not ambiguous for every model.
The later-format lookup covers the five-digit sequence, two date letters and three-digit type code in Browning’s 1976–1997 table; for example, 01001RT151. Do not rearrange the characters. Final Tribute, unusual transitions and other unlisted formats require the manufacturer’s reference.
Sources reviewed September 28, 2026: Browning Auto-5 dating reference and the NRA-hosted Blue Book serialization tables (printed pages 2311–2312; early 12-gauge comparison on page 2310). Read a result as a reference estimate, not authentication or a verified shipping date.
Use the complete receiver serial number, including all letters and prefixes. Browning changed serial-number formats several times, so the letters are just as important as the digits. After using the lookup tool, compare the result with the receiver markings, barrel markings, proof marks, and overall configuration. For help comparing those markings, see the Belgian versus Japanese Auto-5 identification guide. To understand how originality and condition affect collectibility, review the Auto-5 value factors.

This Browning Auto-5 serial number lookup is intended as a collector reference only. Serial number systems can overlap, factory records may vary, and individual firearms may have been repaired, refinished, rebarreled, or assembled from parts during their lifetime.
Treat the result as a helpful starting point, not a factory letter, appraisal, authentication, or legal determination. Always confirm markings, barrel codes, proof marks, configuration, and condition before drawing a final conclusion.
