Month of Manufacture: If the serial number has a four-digit start, the third and fourth digits often represent the month. Example: 0010XXXX was produced in October 2000. Vintage & Non-Standard Numbers

Pre-Mid-1990s: Serial numbers from this era were often randomly generated and do not follow the standard dating format.

"WO" Prefixes: For some Korean-made models with a "WO" prefix, community research suggests the last two digits may actually denote the year.

Model Identification: You generally cannot identify the specific model (e.g., CR250 vs. G250) from the serial number alone.

Technical Overview: Cort Serial Number Identification and Decoding

Cort Guitars, a major global manufacturer of musical instruments, utilizes a serial number system primarily designed to track the production timeline factory origin

of their instruments. Unlike some manufacturers whose codes reveal specific model specifications, a Cort serial number

is primarily an indicator of the year and month of manufacture. This paper outlines the structure of these serials and the methodology for manual decoding in the absence of an official automated "checker" tool. 1. The Core Decoding Logic

The most consistent element in Cort serial numbers is the year of production. According to the Cort General FAQ

, the first two digits of the serial number typically represent the year the instrument was manufactured: : Produced in 2000. : Produced in 2006. : Produced in 2015. 2. Alphanumeric Prefixes and Factory Origins

Many Cort instruments feature a letter prefix before the numeric sequence. These letters indicate the specific facility where the guitar was built. While Cort has historically operated in South Korea, much of its modern production is now centered in

: Refers to the Cort factory in Indonesia (e.g., PT Cort Indonesia). "N" Prefix

: Has been associated with specific production runs or subsidiary facilities. 3. Structural Variations

While the "year-first" rule is standard for modern instruments, older models (pre-2000s) or specific signature series may follow different logic: 7-Digit Serials : Often follow a format, where the first digit is the year (e.g.,

for 1997), the next two are the month, and the final four are the production unit number. 8-Digit Serials : Frequently follow a format, where the first two digits are the year (e.g., for 2004) and the next two are the month. 4. Limitations of "Serial Number Checkers"

It is important to note that while third-party "lookup" sites exist, they often rely on these same general rules rather than a private manufacturer database. A serial number alone cannot identify a specific model

(e.g., identifying a G250 vs. a CR250). To verify a model, the serial number must be paired with visual identification of the headstock, bridge, and electronics. Conclusion They usually reply in 2–5 business days
