The 17th character of a VIN encodes the last character of the VIN — the final serial digit. 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 17th position.
Here it is 3, part of the serial number 976513.
The 17th character is the last character of the entire VIN — the final digit of the sequential serial number (positions 12–17). Because it is the end of the serial, it increments most frequently across a production run.
A valid VIN is exactly 17 characters; if a number has more or fewer, it is not a standard modern VIN. See the VIN validator.
