Cort serial numbers act as "birth certificates," with modern formats (post-1990s) primarily indicating the year and month of production via the first two to four digits, often preceded by factory-identifying letters.

Quick Guide to Cort Serial Numbers (Mid-1990s–Present)

For most modern Cort instruments, the serial number follows a date-coded system where the first two or four digits reveal the production year. Format: YYMMXXXX or YYYYMMXXXX Format B (Early 2000s Chinese/Indonesian): Letter + 4-digit

YY or YYYY: The year of manufacture (e.g., "06" or "2006" for 2006). MM: The month of manufacture (e.g., "10" for October). XXXX: The sequential production number for that month.
