The serial number of the Korg M1 is crucial for several reasons:
Korg sometimes reused number blocks for different markets, so these ranges are estimated guidelines , not absolute rules.
Here's a rough breakdown of the production date and batch number:
While Korg does not typically offer a public serial number lookup tool, you can contact Korg support directly for information. They may be able to confirm the original model or provide production details based on the number, especially for more recent units. Korg M1 Serial Number
Knowing if your M1 is from 1988 (first year) versus 1994 (last year) can change its value.
While the Korg M1’s serial number won’t give you an exact birthday, it offers a solid estimate of the instrument’s era and helps separate early gems from later reliable runners. Whether you’re a collector chasing a triple-digit serial or a gigging musician looking for a late-model workhorse, that little number on the back tells a bigger story than you might think.
Note: Some early production units also had a serial number stamped into the chassis metal, but stickers are more common. The serial number of the Korg M1 is

Unlike some guitar manufacturers, Korg serial numbers are not strictly sequential in a way that is publicly documented for perfect accuracy. However, there are generally accepted formats used by synth technicians and collectors to estimate the age of the unit.
If you own a Korg M1, you own a piece of music history. Released in 1988, the M1 is officially the best-selling synthesizer of all time, moving over 250,000 units. It defined the late-80s and early-90s soundscape, from the iconic "Universe" patch in house music to the "Piano 8" on countless ballads. Knowing if your M1 is from 1988 (first
, released in 1988, is one of the best-selling synthesizers of all time, with an estimated [22, 27]. Because of this massive production run, serial numbers range significantly, but they follow a few identifiable patterns:
Every Korg M1 relies on a CR2032 lithium battery soldered or socketed to the mainboard to retain its user programs and global settings. Knowing the approximate age via the serial number helps estimate how long a pristine, unused unit can go before requiring a battery replacement and a subsequent factory patch reload. How to Locate the Serial Number on a Korg M1
In the vintage synthesizer market, "first-year" production units (1988) with low serial numbers carry a premium for specific purist collectors. Conversely, player-focused buyers often prefer later serial numbers because the internal components have fewer hours of use and benefit from factory-corrected hardware optimizations. What to Do If Your Serial Number Sticker Is Missing
Early M1s use the Yamaha FS keybed , which is highly durable but may develop "sticky" keys over several decades. Korg Serial Numbers (later type) - ZASM
