1. A repository of our manufacturing serial numbers listed out for your convenience.
2. Most will be 5 to 6 digits in length, but the earliest examples feature 4 digit serial numbers. 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.

I just thought I’d share my horn. She’s an oldie but a goodie (though the Horn is silver-plated). After doing some research, I have found out that the serial number indicates that this was among the last Besson Imperials, before the Sovereign and New Standard came along. The Besson Imperial used to be the industry standard back in the 1960s. The last number in the flute sequence is 31199 for an instrument completed 9/5/1950, while the first flute to appear in the reed sequence has the serial number 42799 and was completed 3/11/1949. Despite the overlap in production dates, these numbers appear to have been issued sequentially in.

This section is designed to assist in dating and/or identifying instruments manufactured or distributed by Gibson Guitar Corp. Please note that most of this information relates to serial numbers used from 1975 to present.

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.
The serial number will be an 8 digit number impressed into the back of the headstock with 'MADE IN USA' below.
The pattern is as follows:
YDDDYRRR
YY is the production year
DDD is the day of the year
RRR is the factory ranking/plant designation number.
Prior to 1984 when the Kalamazoo, MI factory was closed, the numbers 001-499 indicated Kalamazoo production. Ranking numbers 500-999 continued to indicate Nashville production through 1989.
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.
Examples: 70108276 means the instrument was produced on Jan. 10, 1978, in Kalamazoo and was the 276th instrument stamped that day.
82765501 means the instrument was produced on Oct. 3, 1985, in Nashville and was the 1st instrument stamped that day.
NOTE - Gibson USA goes to a 9 digit serial number in early July 2005..
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 first 5 numbers remain the same, the last 3 numbers will remain the same. The only difference is the addition of this batch indicator.
There are always exceptions to these rules, the two listed below are worth noting:
Les Paul Classic 1989-2014: 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. 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 1st and 2nd indicate the year of manufacture for the 6 digit serial numbers which we've been using since 2000.
Examples -
9 xxx = 1989 (4 digit number beginning with '9' used only in 1989)
0 xxxx = 1990
9 xxxx = 1999
00xxxx = 2000
05xxxx = 2005
*Note – For Les Paul Classics made in 2007 and later, “MADE IN USA” was added to the back of the headstock
Those beginning with '94':
In 1994, Gibson's Centennial year, many instruments have a serial number that begins with '94' for the year, with the remaining 6 digits indicating the ranking number.
Gibson USA 2014 to present – These serial numbers cannot be dated to a specific day of the year.
The new model year typically launches in the fall as the current model year winds down. It is not uncommon for a new model year model to be produced during the previous model year (example – a 2015 model may have been built in late 2014).
The pattern is as follows:
YYRRRRRRR
YY is the model year
RRRRRRR is the number in product for the model year (starts at 0000001)
1952-1960 Les Paul, Explorer, Flying V, and Futura reissues (since late 1992):
M YRRR or MYRRRR
M is the model year being reissued
Y is the production year
RRR(R) indicates the guitar's place production for that year. NOTE: This number includes all models for a particular reissue year - so, for example, a 1958 Reissue serial number may include '58 Reissue LP Standard and '58 Explorer production.
Example: 7 5123 is the 123rd 1957 reissue model produced in 2005.
1961-1969 Firebird, Les Paul, and SG reissues (since 1997):
YYRRRM

8= 1968 Les Paul Custom
Examples: 050102 is the 10th SG Standard reissue produced in 2005.
030084 is the 8th 1964 Firebird III reissue produced in 2003.
Historic ES MODELS (since 1995):
(A or B)-MYRRR
M is the model year being reissued
Y is the production year
RRR indicates the guitar's place in the sequence of Historic ES production for that year.
Reissue model codes:
2= ES-295
3= 1963 ES-335 (block inlays)
4= ES-330
5= ES-345
9 with an 'A' prefix = 1959 ES-335 (dot inlays)
9 with a 'B' prefix= ES-355
Example: A-38005 is the 5th '63 ES-335 Reissue produced in 1998.
Carved Top models (serial number on orange label)
YDDDYRRR
YY is the production year
DDD is the day of the year
RRR indicate the guitar's place in the sequence of carved tops made that day.

Examples:

20045002 was the 2nd carved top stamped on the 4th day of 2005.
