Understanding Gibson's YDDDYRRR Serial Number Format
The most common Gibson serial number format — used on Gibson USA and Gibson Acoustic guitars from 1977 to present — is the 8-digit YDDDYRRR system. Here's a detailed breakdown of how to decode each part:
1st & 5th digits combine to form the last two digits of the production year
Digits 2–4 represent the day of the year (001 = January 1, 365 = December 31)
Last 3 digits indicate factory ranking (001–499 = Kalamazoo pre-1984, 500–999 = Nashville)
This format applies to the vast majority of Gibson guitars you'll encounter from 1977 onwards, including Les Paul Standard, Les Paul Studio, Les Paul Traditional, SG Standard, SG Special, Flying V, Explorer, Firebird, and Gibson acoustic models like the J-45, Hummingbird, Dove, J-200, and L-00.

Gibson Serial Number Lookup by Model
Different Gibson guitar models may use distinct serial number formats. Here's how serial numbers work for the most popular Gibson models:
Gibson Les Paul Serial Number
Les Paul Standard, Studio, Traditional, and Tribute models use standard Gibson USA 8 or 9-digit formats. Les Paul Custom guitars from the Custom Shop use CS-prefix numbers. Les Paul Classic (1989–2014) uses unique 4–6 digit ink-stamped numbers without 'Made in USA'. The Les Paul Deluxe, Les Paul Special, and Les Paul Junior all follow standard USA numbering.
Gibson SG Serial Number
SG Standard, SG Special, SG Junior, and SG Custom models all use the standard Gibson USA serial number format. Custom Shop SG reissues have impressed YRRRRM numbers where the last digit indicates the reissue year: 1 = 1961 SG Standard, 2 = 1962 SG Standard/Custom, 3 = 1963 SG models, 4 = 1964 SG Standard.
Gibson ES-335 Serial Number
The ES-335 and other semi-hollow models (ES-345, ES-355, ES-339, ES-175) made at Gibson Memphis use standard Gibson USA tracking. Custom Shop ES reissues have special formats: A8YRRRR for 1958 ES-335 reissues (ink-stamped on F-hole label) and 1YRRRR for 1961/1964 ES reissues (impressed on headstock + F-hole label).
Gibson Acoustic Serial Number
Gibson acoustics built in Bozeman, MT since 1989 — including the J-45, Hummingbird, Dove, J-200/SJ-200, L-00, J-15, and G-45 — use the same YDDDYRRR (8-digit) or YDDDYBRRR (9-digit) formats. Bozeman ranking numbers start at 001 each day. Pre-1989 acoustics were made in Kalamazoo and Nashville.
Gibson Custom Shop Serial Number
Custom Shop instruments use several formats: CSYRRRR (modern, ink-stamped), MYRRR or MYRRRR (reissue, ink-stamped, where M = model year digit), YRRRRM (impressed, where last digit = reissue model year), and YDDDYRRR for carved-top models. The 'CS' prefix always indicates Custom Shop origin.
Gibson Explorer, Flying V & Firebird
Explorer, Flying V, and Firebird models follow standard Gibson USA serial number formats. Custom Shop reissues of these models use special formats: the Korina Flying V and Korina Explorer reissues have the '8' reissue digit (for 1958), and Firebird reissues use '3' (1963) or '5' (1965 Non-Reverse). The Dark Fire and other specialty models may have unique numbering.
Gibson Factory Locations & How to Identify Them
Knowing where your Gibson was manufactured adds historical context and can affect its value. The factory location is encoded in the ranking digits (RRR) of your serial number. Here's a complete guide to Gibson's production facilities:
Kalamazoo, MI
1902–1984
Gibson's original factory and headquarters where every Gibson was built until Nashville opened. On 8-digit serial numbers from 1977–1984, ranking numbers 001–499 indicate Kalamazoo production. Kalamazoo-made Gibsons are highly sought after by collectors for their superior craftsmanship and historical significance. Models include vintage Les Pauls, SGs, ES-335s, and all pre-1984 instruments.
Nashville, TN
1974–Present
Gibson's primary electric guitar production facility and current headquarters. Ranking numbers 500–999 on 1977–1989 serials indicate Nashville. After 1989, Nashville electrics may start ranking in the 300s. Home to the Gibson Custom Shop, which produces reissues, artist models, and limited editions. All current Les Paul, SG, Flying V, Explorer, and Firebird production happens here.
Bozeman, MT
1989–Present
All Gibson acoustic guitars have been handcrafted in Bozeman, Montana since 1989. Daily ranking numbers start at 001. This facility produces the legendary J-45, Hummingbird, Dove, SJ-200, L-00, J-15, G-45, and all Gibson acoustic instruments. Bozeman-made acoustics are renowned for their tone and quality, continuing Gibson's acoustic heritage.
Vintage Gibson Serial Numbers (Pre-1975)
Gibson serial numbers prior to 1975 followed less standardized formats that varied significantly across different eras. Vintage Gibson serial number lookup requires understanding these older systems:
1902–1947: Early Gibson Era
Early Gibson instruments used a variety of numbering systems. Many were simple sequential numbers. Mandolins, banjos, and guitars each had their own numbering sequences. Some instruments from this period have no serial number at all. Factory Order Numbers (FON) were also used internally and can sometimes help date instruments.
1947–1961: Post-War Numbering
Gibson used a roughly sequential numbering system, but numbers were reused and inconsistencies are common. The ink-stamped numbers were typically 5–6 digits on the back of the headstock. Cross-referencing with Factory Order Numbers and model features is often necessary for accurate dating of this era.
1961–1975: Transition Era
Serial numbers during this period were often inconsistent, with numbers reused across different years. From 1970–1975, various stamping methods were used. Impressed numbers, ink-stamped numbers, and decals all appeared during this transitional time. The 1975–1977 decal format (8 digits starting with 99, 00, or 06) began the move toward standardization.
For pre-1975 Gibson guitar identification and dating, we recommend contacting Gibson directly at service@gibson.com or consulting a qualified vintage guitar expert. Our tool currently supports Gibson serial numbers from 1975 onwards, covering the standardized era. We plan to add vintage Gibson serial number decoding in a future update.
How to Date a Gibson Guitar by Serial Number
Dating a Gibson guitar is one of the most common reasons people search for serial number information. Here's a quick reference for determining your Gibson's production year based on the serial number length:
| Serial Number Length | Likely Format | Era | Year From |

| 6 digits | Les Paul Classic / Custom Impressed | 2000–2014 | First 2 digits = year (LP Classic) or 1st digit (Custom) |
| 5–7 digits (CS prefix) | Gibson Custom Shop | 1993–present | Digit after CS = last digit of year |
| 8 digits (YDDDYRRR) | Gibson USA / Acoustic standard | 1977–present | 1st + 5th digits = last 2 digits of year |
| 8 digits (94xxxxxx) | 1994 Centennial | 1994 | Always 1994 |
| 8 digits (99/00/06 prefix) | 1975–1977 Decal | 1975–1977 | 99 = 1975, 00 = 1976, 06 = 1977 |
| 9 digits (YDDDYBRRR) | Gibson USA with batch | 2005–2014, 2019+ | 1st + 5th digits = year |
| 9 digits (YYRRRRRRR) | Gibson USA production# | 2014–2019 | First 2 digits = year |
