Korg M1 Serial Number < TESTED | HACKS >

Beyond simple curiosity, your Korg M1's serial number plays several important roles.

The serial number is a six-digit number or a combination of digits indicating production, as Korg transitioned to sequential numbering for their popular 1980s products. Decoding the Korg M1 Serial Number

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

Serial 012345 suggests a 1988–1989 unit. Serial 198765 suggests a 1992–1993 unit.

Unlike some manufacturers, Korg didn’t use a straightforward “YYMMDD” system. However, a clear pattern exists based on cumulative production. Korg M1 Serial Number

Lower numbers indicate early Japanese production runs, while higher numbers indicate later runs. Estimating Production Year Serial Number Range Estimated Production Year Production Era 000001 – 040000 Early Launch / First Edition 040001 – 110000 Peak Production Era 110001 – 180000 Mid-Lifecycle Run 180001 – 220000 1991 – 1992 Late Production Run 220001+ / M1R variant 1993 – 1994 Final Units / End of Life ⚙️ Hardware Revisions Linked to Serial Numbers

Understanding how to date your M1 using the serial number allows you to accurately assess its place in the instrument’s production timeline, which directly correlates to its rarity and, therefore, its value.

An authentic factory M1EX or M1REX with the correct stamped serial number is significantly more valuable than a standard M1R that has been user-upgraded, even if the functionality is similar.

The serial number is often stamped directly onto the main PCB (Printed Circuit Board). This requires unscrewing the bottom chassis panel. Beyond simple curiosity, your Korg M1's serial number

If you want to dive deeper into restoring a specific unit, let me know:

: All hardware M1 units were manufactured by Korg during its peak workstation era. Finding Serial Numbers for Software Versions If you are using the digital recreation, such as the Korg Collection M1 Go to product viewer dialog for this item. , the "serial number" is your Product Code .

Unlike modern manufacturers who use alphanumeric codes containing explicit date formulas (like year/week characters), Korg utilized a for the M1. Sequential Numbering System

Finding the serial number on your Korg M1 is the first step toward verifying its age and history. Because the M1 was produced in such high volume—estimated at over 250,000 units between 1988 and 1995—serial numbers are the most reliable way to track its production timeline Serial Number Location The serial number is typically found on the bottom of the unit While Korg does not offer an official public

Korg M1 serial numbers are entirely numeric, typically ranging from 5 to 6 digits.

The Korg M1, released in 1988, is arguably the most influential digital synthesizer of all time. With over 250,000 units sold between 1988 and 1995, it defined the early 90s house sound and revolutionized music production through its "workstation" concept.
