The 15th character of a VIN encodes part of the sequential production serial number. It falls in the Serial (12–17) block of the 17-character VIN. Below is exactly what it means, with a real sample VIN highlighting the 15th position.
Here it is 9, part of the serial number 462997.
The 15th character is one of the serial digits (positions 12–17). The serial increments as vehicles roll off the line, so this position changes from one unit to the next in the same production run.
Like the rest of the serial, it is assigned sequentially by the manufacturer and is not derived from the vehicle's specification.
