Where to find it
On Doosan and Develon excavators the identification plate is on the right side of the cab, below the windshield, the same location used by Caterpillar and John Deere. The serial number is also commonly stamped on the frame, so confirm the plate matches the stamped number.
How the format works
Older Doosan (and Daewoo-era) machines used a short serial number of roughly three to five digits. Modern machines carry a 17-character PIN built to the international VIN standard. On a standard 17-character PIN the tenth character encodes the model year, and the identification plate usually lists the year directly.
MachVerity reads the model year from a standard 17-character PIN automatically.
Confirming the exact year and model
The plate is the most direct source for the year. For older short serials, or to confirm the exact model and build details, give the full serial to an authorized Doosan or Develon dealer.

Frequently asked
Where is the serial number on a Doosan excavator?
On the identification plate on the right side of the cab below the windshield, the same place as Caterpillar and John Deere. It is also stamped on the frame.
Is Doosan the same as Develon?
Yes. Doosan construction equipment is now branded Develon. Older machines carry the Doosan (and earlier Daewoo) name, but the serial-plate locations are the same.
Can you tell the year from a Doosan serial number?
If the machine has a standard 17-character PIN, the tenth character encodes the model year, and the plate usually lists it directly. Older short serials do not encode the year, so use the plate or a dealer.
