Serial Number Tips by Brand
Gibson Serial Numbers
Pre-1977 Gibson serials used batch letters (A, B, etc.) and are approximate — pot codes inside the guitar are more reliable for exact dating.
From 1977 onward, Gibson used an 8-digit system where digits 2-4 indicate the day of the year and the last digit indicates the year.
FON (Factory Order Number) stamps on the inside back of the guitar body provide additional dating information for pre-1961 guitars.
Fender Serial Numbers
Pre-CBS Fender serials (before 1965) were stamped on the neck plate and are not strictly sequential — ranges overlap between years.
The neck date stamp (written in pencil inside the neck pocket) is the most reliable way to date a vintage Fender. The body may also have a stamp.
Check pot codes: the last 2 digits indicate year, the 3-4 digits before that indicate the week of production.
Martin Serial Numbers
Martin has maintained sequential serial numbers since 1898, making their guitars the easiest to date accurately.
Simply look up the serial number in our Martin serial number table to find the exact year of production.
