Gibson custom shop serial dating

There should be a space after the 1st digit with the 4 and 5 digit serial numbers, and no space with the 6 digit numbers.The 1st digit indicates the year of manufacture for the 4 & 5 digit serial numbers, these were used from 1989-1999.

The 2014 Model Year introduces a new numbering system, the model year indicated by the first 2 digits. Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers.The sixth number is now a batch number- batch 0 starts at the beginning of the day, and once we stamp 699, the batch number will change to 1.The only difference is the addition of this batch indicator.- From 1975-1977 the number is typically found on a decal on the back of the headstock.This should be an 8 digit number that can be dated by the 1st and 2nd digits as follows: 99 = 1975 00= 1976 06 = 1977 - In 1977, Gibson introduced the serialization method that we primarily use to this day at Gibson USA, Gibson Acoustic, and the Gibson Custom facility in Memphis, TN.
