Ranking numbers for Bozeman start each day at 001 and the electrics may start as low as the 300s.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.From 1902 to 1976, Gibson instruments have a serial number or a FON (Factory Order Number) or both.However, in the beginning this was not done consistently, so that there are also be instruments without identification.
The 1st digit indicates the year of manufacture for the 4 & 5 digit serial numbers, these were used from 1989-1999.(G = Gibson, K = Kalamazoo, W = Recording King (Montgomery Wards).If follows there is a third letter E, it stands for Electric.Some instruments from the fifties also had been such a stamp. At serialization in the 70s a random method was used.Guitars got six digits in any order, and in some cases they were preceded by a letter that none seemed to have no smeaningful sense.Les Paul Classic: This model features an ink stamped serial number with no "MADE IN USA" (just as we used on the original 1952-1960 Les Pauls).Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers.Also in 19 there was a high production, "9 9999" is exceeded for "932 000" or higher.Therefore, the production in 1959 may be a "1", "2" or "3" in the second digit.Knowing how to identify correct serial numbers still remains one of the best and most effective ways to date your Gibson, and at the same time confirm its authenticity. Please note that most of this information relates to serial numbers used from 1975 to present.For more details on Gibson Serialization prior to 1975 and historical product specs, use your Gruhn's Guide or view the following PDF files: Since 1989, all Gibson acoustics are built in Bozeman, MT and all Gibson electrics are built in Nashville or Memphis.
