Field notes
The homepage directs users to copy the serial exactly and warns that model numbers, part numbers and dates stamped on necks or electronics are separate identifiers. Coverage varies by brand: the listed Martin method uses the last number used each year, while the Taylor decoder describes 9-, 10- and 11-digit layouts. The site says it does not estimate values and that a serial date is not proof of authenticity.
