Every position in a 17-digit Subaru VIN decoding has significance. The World Manufacturer Identifier is comprised of a combination of the first three positions. The first position is the country code for manufacturing, which for Subaru, could be a J for Japan. The second position is the manufacturer, and in the case of decoding a Subaru VIN, you would be looking for S. The third position is the vehicle type. As an example, if the first three positions show 4S4, this would be a Subaru-Isuzu factory multi-purpose vehicle, like the 2005 Outback.
The fourth position is the line type, such as B for Legacy, S for Forester, or G for Impreza. Then in the fifth position, the body of the car is revealed, such as a sedan or wagon. In position six, the engine type is indicated, such as 2 for 2.0L turbo 4 cyl or 8 for a 3.0L 6 cyl. Position 7 will tell you the model type and trim. The eight position is the type of restraint system used, such as 5 for manual seat belts with front dual airbags.
The ninth position is home to the “check” digit, which is used to identify any fraudulent VINs. Only the manufacturer and law enforcement know this number, which is actually a mathematical formula that takes into account all of the other numbers in the Subaru VIN.
The tenth position in Subaru VIN decoding shows the model year, while the eleventh position is the vehicle’s assembly plant.
Lastly, the final six digits are a serial number unique to that specific vehicle, indicating its position in the assembly line. As an example, if the last six positions were 733987, then as we perform Subaru VIN decoding, we would know this would have been the 733,987th Subaru Forrester of the production year to be completed on the assembly plant’s line that year.
