Ibanez Guitar Serial Number Lookup/Decoder

Founded in 1908 as Hoshino Gakki, a Japanese bookstore chain that began importing Spanish guitars, Ibanez has evolved into a premier manufacturer of guitars, basses, and amplifiers. Known for high-performance instruments favored by rock and metal artists, the company is renowned for its "lawsuit era" copies in the 1970s, which led to iconic original designs like the JEM, RG, and S series.

Ibanez Serial Number Lookup/Decoder FAQs

Where can I find the Ibanez serial number?

Most Ibanez guitars list the serial number on the back of the headstock. Some acoustics place it inside the soundhole on a paper label, and older instruments may use a neck plate or stamped marking. If you cannot find it, check the headstock back and the neck joint first.

What can this Ibanez serial number lookup/decoder tell me?

It typically identifies the production year, factory or plant code, and country of origin. Some serial formats also hint at model lines or production sequence, but that varies by era.

Why won't my Ibanez serial number decode?

Serial formats change over time, and limited runs or custom shop instruments can deviate from standard patterns. The decoder now retries common formatting fixes automatically (such as removing spaces/hyphens), but some serials still require manual review. Also, model codes (for example SR305EDX or GRG170DX) are not serial numbers and usually cannot provide exact month/year without the actual stamped serial.

How to decode an Ibanez serial number

Ibanez serial numbers are generally found on the back of the headstock and can often be decoded by prefix plus date digits. A common modern pattern is factory prefix + YYMM + sequence (for example, I160100231 = Indonesia, January 2016). This decoder also supports GI + 7 digits legacy Indonesia GIO format (e.g., GI0012180 = December 2000), 5A/5B/5N + 9 digits (two-character import prefix with YYMM date digits), 4H/OZ + 9 digits (China two-character/two-letter prefix variants), 4H + 10 digits (extended China variant: YY + batch/line + MM + sequence, e.g., 4H2300501778 = May 2023), H + 9 digits (China H-prefix variant), China GIO-style GZ + 9 digits (e.g., GZ150102324 = January 2015), SQ + YY + month-letter + sequence for some Saehan acoustic production (e.g., SQ08E06597 = May 2008), Korean 1990s C + 7 digits (e.g., C8016949 = January 1998), B + 9 digits (month-letter variant where B = February), China L/N + 9 digits variants (e.g., L160200319 and N230401406), numeric-only 7-10 digits interpreted as date + sequence on import variants (e.g., 220600378 = June 2022, 02010903 = January 2002, 4120210 = December 2014 using YMM + sequence, 5230401406 = April 2023 with leading factory digit), legacy YYMM###/#### + 1-2 letters formats (e.g., 83030041D and 8303004ID = March 1983), and compound codes like 212Y03GS251101952 or 215N015N250401143 where an internal prefix is prepended to a standard date payload.

Decoding by Location & Year

Japan (FujiGen, 1987–Present): Starts with a letter, followed by 6–7 digits. The first two digits after the letter are the year (e.g., F97XXXX = 1997).
Indonesia (2001+): Usually I/K/J/U + 9 digits with YYMM + sequence (e.g., U081100181 = November 2008). An extended +10 digit variant also appears as YY + line + MM + sequence (e.g., I1161207864 = December 2011).
Indonesia GIO Legacy: GI + 7 digits appears on some early GIO production (e.g., GI0012180 = December 2000).
Import Prefix Variants: Some serials use non-standard import prefixes with + 9 digits (for example, 5A, 5B, 5N, 4H, OZ, or H); the decoder treats these as factory/line codes and uses the remaining digits as YYMM + sequence (e.g., 5A210401373 = April 2021, 5B160100231 = January 2016, 5N230401406 = April 2023, 4H140800605 = August 2014, OZ100500158 = May 2010, H081100181 = November 2008). A 4H extended variant with + 10 digits is also supported as YY + batch/line + MM + sequence (e.g., 4H2300501778 = May 2023). Some Saehan acoustic serials use SQ + YY + month-letter + sequence (e.g., SQ08E06597 = May 2008).
Korea 1990s C-prefix 7-digit Variant: Some Korean Cort serials appear as C + 7 digits and are parsed as YMM + sequence (for example, C8016949 = January 1998 at Cort).
Month-letter Variant: Some serials appear as B + 9 digits; in this case the leading letter is treated as month code (A=Jan, B=Feb, etc.) rather than factory code (e.g., B160100231 = February 2016).
Numeric-only Import Variant: Some modern imports use 8-10 digits only with no leading letters; these are decoded primarily as YYMM + sequence (or factory-digit + YYMM + sequence on some 10-digit runs) (e.g., 220600378 = June 2022, 02010903 = January 2002, 5230401406 = April 2023). If YYMM yields an invalid month on 8- or 9-digit serials, the decoder falls back to YMM + sequence and includes an alternate-year note (e.g., 40800605, 311717707).
6-digit Numeric Variants: Some serials are read as YYMMSS (e.g., 041195 = November 2004, with possible 1994 vintage alt-read), some fit pre-letter YMMNNN (e.g., 402989 = February 1974 with an alternate 1984 read), while others fit late-80s YY + sequence (e.g., 881865), often tied to USA-linked assembly or omitted-prefix Japanese runs.
World Short WK Format: Some Korean World factory serials appear as WK + 4 digits (e.g., WK1007). These can have more than one plausible interpretation, so the decoder returns a primary parse and includes an alternate-read note.
Korea/China/Other Imports: Often use a factory letter/prefix followed by year-month style digits, but exact rules vary by plant and era.
Older Models (Pre-1976): Often have no serial number.
Pedals: The first digit of a 4-digit serial number typically represents the last digit of the year (e.g., “3” = 1983).

Key Identification Clues

Letter Prefix: Identifies factory/origin (e.g., F/J = Japan, I = Indonesia, C = China, K = Korea).
First 2 Digits (Modern): Represent the year (e.g., 05 = 2005).
Input Cleanup: If your serial includes spaces/hyphens (e.g., B-160100231), likely character misreads like O vs 0 (e.g., I11o626774, Ao3oooo9), or the known HU variant (e.g., HU081100181), the decoder retries normalized variants automatically and updates the serial box when a corrected format succeeds.
Model vs Serial: Entries like SR305EDX or GRG170DX are model names, not serial numbers. They can suggest likely country/factory, but exact dating needs the stamped serial number.
