- 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. The serial number will be an 8 digit number impressed into the back of the headstock with MADE IN USA below.

Do all Gibsons have serial numbers?

Keep in mind, Gibson never inked serial numbers on the Gibson Les Paul Standard but they did ink the custom shop series and some Les Paul Classics. Another thing to look for is whether the numbers are too close. Fakes are often too close. The fake one on the right has no serial number at all.
