GIBSON SERIALIZATION
Identifying Gibson instruments by serial number is tricky at best and downright impossible in some cases.
The best methods of identifying them is by using a combination of the serial number, the factory order
number and any features that are particular to a specific time that changes may have occurred in instrument
design (i.e. logo design change, headstock volutes, etc). There have been 6 different serial number styles
used to date on Gibson instruments.
The first serialization started in 1902 and ran until 1947. The serial numbers started with number 100 and
go to 99999. All numbers are approximates. In most cases, only the upper end instruments were assigned
identification numbers.

White oval labels were used on instruments from 1902 to 1954, at which time the oval label was changed to
an orange color. On instruments with round soundholes, this label is visible directly below it. On f-hole
instruments, it is visible through the upper f-hole. The second type of serial numbers used started with an A
prefix and ran from 1947 to 1961. The first number is A 100.

When production of solid body guitars began, an entirely new serial number system was developed.
Though not used on the earliest instruments produced (those done in 1952), a few of these instruments have
3 digits stamped on the headstock top. Some time in 1953, instruments were ink stamped on the headstock
back with 5 or 6 digit numbers, the first indicating the year, the following numbers are production numbers.
The production numbers run in a consecutive order and, aside from a few oddities in the change over years
(1961-1962), it is fairly accurate to use them when identifying solid body instruments produced between
1953 and 1961. Examples of this system:
4 2205 = 1954 614562 = 1956
In 1961 Gibson started a new serial number system that covered all instrument lines. It consisted of
numbers that are impressed into the wood. It is also generally known to be the most frustrating and hard to
understand system that Gibson has employed. The numbers were used between the years 1961-1969. There
are several instances where batches of numbers are switched in order, duplicated, not just once, but up to
four times, and seem to be randomly assigned, throughout the decade. In general though, the numbers are
approximately as follows:

From 1970-1975 the method of serializing instruments at Gibson became even more random. All numbers
were impressed into the wood and a six digit number assigned, though no particular order was given and
some instruments had a letter prefix. The orange labels inside hollow bodied instruments was discontinued
in 1970 and were replaced by white and orange rectangle labels on the acoustics, and small black, purple
and white rectangle labels were placed on electric models.
In 1970, the words “MADE IN USA” was impressed into the back of instrument headstocks (though a few
instruments from the 1950s also had MADE IN USA impressed into their headstocks as well).

and a few A-B-C-D-E-F + 6 digit numbers
During the period from 1975-1977 Gibson used a transfer that had eight digit numbers, the first two
indicate the year, 99=1975, 00=1976 and 06=1977, the following six digits are in the 100000 to 200000
range. MADE IN USA were also included on the transfer and some models had LIMITED EDITION also
applied. A few bolt on neck instruments had a date ink stamped on the heel area.
In 1977, Gibson first introduced the serialization method that is in practice today. This updated system
utilizes an impressed eight digit numbering scheme that covers both serializing and dating functions. The
pattern is as follows:
YDDDYPPP
YY is the production year
DDD is the day of the year
PPP is the plant designation and/or instrument rank.
The numbers 001-499 show Kalamazoo production, 500-999 show Nashville production. The Kalamazoo
numbers were discontinued in 1984.
When acoustic production began at the plant built in Bozeman, Montana (in 1989), the series’ numbers
were reorganized. Bozeman instruments began using 001-299 designations and, in 1990, Nashville
instruments began using 300-999 designations. It should also be noted that the Nashville plant has not
reached the 900s since 1977, so these numbers have been reserved for prototypes. 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.
However, it has come to light recently that the Kalamazoo plant did not directly switch over to the “new” 8
digit serialization method in 1977. When the Nashville Gibson plant was opened in 1974, it was decided
that the bulk of the production of products would be run in the South; the Kalamazoo plant would produce
the higher end (fancier) models in the North. Of course, many of the older guitar builders and craftsmen
were still in Kalamazoo; and if they weren’t ready to change how they built guitars, then they may not have
been ready to change how they numbered them! Certain guitar models built in the late 1970s can be used
to demonstrate the old-style 6 digit serial numbers . It is estimated that Gibson’s Kalamazoo plant
continued to use the 6 digit serial numbers through 1978 and 1979. So double check the serial numbers
on those 1970s L-5s, Super 400s, and Super 5 BJBs!
Gibson’s F O N System
In addition to the above serial number information, Gibson also used Factory Order Numbers (F O N) to
track batches of instruments being produced at the time. In the earlier years at Gibson, guitars were
normally built in batches of 40 instruments. Gibson’s Factory Order Numbers were an internal coding that
followed the group of instruments through the factory. Thus, the older Gibson guitars may have a serial
number and a F O N. The F O N may indicate the year, batch number, and the ranking (order of production
within the batch of 40).
This system is useful in helping to date and authenticate instruments. There are three separate groupings of
numbers that have been identified and are used for their accuracy. The numbers are usually stamped or
written on the instrument’s back and seen through the lower F hole or round soundhole, or maybe
impressed on the back of the headstock.

F O Ns for the years 1935-1941 usually consisted of the batch number, a letter for the year and the
instrument number. Examples are as follows:
722 A 23
465 D 58
863 E 02.
Code Letter and Year
A 1935
B 1936
C 1937
D 1938
E 1939
F 1940
G 1941
Code Letter F O Ns were discontinued after 1941, and any instruments made during or right after World
War II do not bear an F O N codes. In 1949, a four digit F O N was used, but not in conjunction with any
code letter indicating the year.
From 1952-1961, the F O N scheme followed the pattern of a letter, the batch number and an instrument
ranking number (when the guitar was built in the run of 40). The F O N is the only identification number
on Gibson’s lower grade models (like the ES-125, ES-140, J-160E, etc.) which do not feature a paper label.
Higher grade models (such as the Super 400, L-5, J-200, etc.) feature both a serial number and a F O N.
When both numbers are present on a higher grade model, remember that the F O N was assigned at the
beginning of the production run, while the serial number was recorded later (before shipping). The serial
number would properly indicate the actual date of the guitar. F O N examples run thus:
Y 2230 21
V 4867 8
R 6785 15

Z 1952
Y 1953
X 1954
W 1955
V 1956
U 1957
T 1958
S 1959
R 1960
Q 1961
After 1961 the use of FONs was discontinued at Gibson.
There are still some variances that Gibson uses on some instruments produced today, but for the most part
the above can be used for identifying instruments. For the most accurate identification you would need to
contact the Gibson Guitar Corporation itself.
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: 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
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 Goldtone Amps

Back in the 1950s, if you bought a brand new Les Paul Standard your guitar would have been equipped with a Brazilian Rosewood fingerboard.  The original specification of many Gibson guitars back the day called for the Brazilian species of Rosewood; it was considered ideal for guitar making.  What’s the difference?  Rosewood is Rosewood, right?  Not exactly.  Brazilian Rosewood is often darker, with chocolate-y streaks in the grain.  Also, because it can be slightly denser and harder than other types of Rosewood, might provide a little extra sonic “punch” compared with other, softer varieties.  Since 1991, Brazilian Rosewood has been listed as an endangered species and has therefore been used sparingly by guitar makers.

However, there have been some small runs here and there of Gibson guitars that do have Brazilian fingerboards, particularly during 2001-2003.  And again, in 2017-2019. In ’03 Gibson released the revamped Historic Reissues and for a few months only, all the guitars had Brazilian.  The guitars that Gibson has verified, using a serial number range, as having these Brazilian boards have enjoyed a substantial price bump in the marketplace, so knowing if yours is truly Brazilian, Gibson verified, can prove useful.  Follow the jump to see the complete serial number guide.

The following information is posted on Gibson’s Forum, by the Gibson administrator:
