The 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

No known "clone" cases exist. However, there are many "M1s" that are actually 01/W or T3 boards stuffed into an M1 case. Check that the serial number on the board matches the case. If the case number is 85000 but the board says 400000, avoid it.

The M1’s serial numbers appear to follow a , with lower numbers produced earlier in the production run. Korg’s manufacturing dates are publicly known, allowing us to map these numbers.
Numbers starting below 50,000 generally denote first-year production models (1988). As production scaled drastically in 1989 and 1990, numbers quickly climbed past the 150,000 mark.
In the digital age, serial numbers are often seen as sterile data points. But for the Korg M1—a machine responsible for the piano and bass sounds on countless 1990s house, techno, and pop records—the serial number is a thread connecting the musician to a specific moment in manufacturing history. A low "1" prefix means your M1 rolled off the line in Tokyo during the synth-crazed frenzy of 1988, carrying with it the risk of faulty capacitors but also the raw, unadulterated firmware that powered "The House Sound of Chicago." A high "3" prefix represents a late-model, battle-hardened workhorse, built for reliability in the waning days of the M1’s reign.
