Korg M1 Serial Number «95% VERIFIED»

The Korg M1 serial number is typically a 6-digit number found on the back panel of the unit. While Korg does not offer an official public decoder for vintage serials, manufacturing history and user data provide clear benchmarks for dating these units. Serial Number Breakdown & Timeline

1. The Rear Panel (Primary): Look for a silver or black sticker near the power cord inlet or the MIDI ports. It will read “Serial No.” followed by a 6-to-8 digit alphanumeric string (e.g., 305456 or 008765).
2. The Main PCB (Internal): For units where the rear sticker is missing or illegible (common after 30+ years), the same number is often printed directly on the main circuit board. This is the “gold standard” for authenticating a chassis.
