Korg M1 Serial Number -

The Ultimate Guide to Your Korg M1 Serial Number The Korg M1 is widely celebrated as the best-selling synthesizer in history, with roughly 250,000 units produced between 1988 and 1995. If you own one of these iconic workstations, its serial number is more than just a label—it's a window into its history and production era. Where to Find the Serial Number

• The Back Panel (Primary): Look for a white or silver sticker on the rear panel. It usually contains the model name (KORG M1), voltage info, and a sequence of numbers often preceded by a letter or numbers indicating the year.
• The Internal Metal Frame: If the sticker on the back is missing or worn, open the unit. There is often a serial number stamped on the main metal chassis near the power supply or printed on the main circuit board.

Practical steps before buying

1. Request clear photos of the serial on the rear panel and beneath chassis (if seller allows).
2. Ask for a short live video showing the serial and power-on demo.
3. Compare pics with verified examples from trusted sources or community archives.
4. If the unit is claimed “early” or “rare,” seek extra documentation (original receipt, service invoices).

Korg transitioned its numbering system in 1983. For the M1 era (1988–1995), the serial numbers are strictly numerical (usually 6 digits) and do not contain embedded date codes like "YYMM". Instead, dating is determined by comparing your number to known production milestones: Korg M1 Serial Number

• Lack of public decoding table: Korg hasn’t published a simple, authoritative public key tying every M1 serial to an exact year and factory. Enthusiast communities and repair shops have reconstructed partial correlations, but these are based on samples and should be treated as approximate.
• Serial tampering: On older keyboards, serial plates can be removed or altered, and internal boards might carry their own identifiers that don’t match the external plate. When verifying authenticity, inspect both the chassis plate and internal PCB labels.
• Overlap with variants: M1EX, rackmount M1R, and later reissues may use related but distinct numbering schemes; don’t assume all “M1” labeled gear shares the same serial format.

Note: Some early production units also had a serial number stamped into the chassis metal, but stickers are more common. The Back Panel (Primary): Look for a white
