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.
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.

We have recently (7 Aug) completed a "clean-out" of old listings in the Gearslutz Member Services directory.Any & all listings that were posted more than 365 days ago have been deleted so that we can ensure the directory remains up-to-date. has recently made changes to their hosting service and embedding images on forums etc does not always work without paying them a large sum of money annually.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.
