the check digit is calculated using a mathematical calculation based on VIN position, sample VIN, assigned value code, weight and other factors. The values are then added together and the sum is divided by 11. The result is the check digit number.
Note the 10th character, which identifies the vehicle’s model year. For example, 1988(J), 1989(K), 1990(L), 1991(M), 1992(N), 1993(P), 1994(R), 1995(S), 1996(T), 1997(V), 1998(W), 1999(X), 2000(Y), 2001(1), 2002(2), 2003(3).
Note the 11th character, which identifies the assembly plant where the vehicle was assembled. The 12th to 16th digits are series numbers used for identifying your specific vehicle. These digits are always numeric, and they identify the sequence of the vehicle production as it comes off the manufacturer’s assembly line. For example, the first vehicle to roll off the assembly line might be 00001, while the second might be 00002 (depending on the manufacturer’s construction of series numbers).
