The Korg M1R (Rackmount) Serial Numbers
This article focuses on the keyboard, but briefly: The M1R serial numbers usually start with a letter (e.g., A12345). The letter denotes the factory of origin.
- A = Japan (Early)
- B = Japan (Late)
- C = Italy (Common for European markets)
Do not confuse M1R serials with the keyboard M1. They are not cross-compatible for dating purposes. Korg M1 Serial Number
Part 1: Locating the Serial Number on Your Korg M1
Before we decode, we must find. The Korg M1 has three potential locations for its serial number, depending on the production year. Collectors call these "Gen 1," "Gen 2," and "REV B" locations.

If you are trying to verify a specific unit for a purchase, checking the M1 Serial Database threads on vintage synth forums (like GearSpace or Korg Forums) is your best bet. Enthusiasts often compile lists of serial numbers to narrow down production weeks. The "solid feature" regarding the Korg M1 Serial
Summary Checklist for Buyers:
- Locate the sticker on the back.
- Check if it says "Made in Japan" or "Made in USA."
- Assume the internal battery is dead and needs replacing (a $5 part, but requires opening the synth).
- Check that all keys work, as the aftertouch rubber strips degrade over time regardless of serial number.
Era 3: The M1EX and Late Models (Prefix: "M1EX-")
Format Example: M1EX-87654
In 1991, Korg released the M1EX, which included the PCM expansion card pre-installed. These serial numbers are distinct.
- The serial is almost always on a holographic sticker (to prevent counterfeiting).
- M1EX-70000 to 99999 were the final units sold in 1994-1995. These are desirable because they have the most reliable keybed (the "newer" Fatar mechanism) and updated capacitors.
My serial number sticker is missing. What do I do?
Open the synth. Look for the white ink stamp on the main circuit board. That is your "true" internal serial number. Write it on the back chassis with a silver Sharpie to help the next owner. A = Japan (Early) B = Japan (Late)
