The 13th 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 13th position.
Here it is 2, part of the serial number 322996.
The 13th character is part of the serial number (positions 12–17). This block is the unique sequential identifier for the individual vehicle — the part of the VIN that guarantees no two cars from the same make/model/year/plant share a number.
For most mass-market vehicles these positions are pure digits (0–9).
