Guitar Serial Number dates guitars, basses and amps from serial numbers using each manufacturer's published formats. It covers Fender, Squier, Gibson (1975 onward), Epiphone, Martin, Taylor and PRS. Fender acoustics get a model-name lookup instead of a serial decoder, and each format links to a sourcing page.
Coverage limits are stated: newer Squier serials usually cannot be dated, a date does not authenticate an instrument, and the site gives no price estimates. It is an independent reference, not affiliated with, endorsed by or sponsored by any manufacturer.
The goal is to make these references easier to find and keep coverage limits visible. The site links to source material instead of guessing unsupported answers.
