After having worked for the Florida Dept of Motor
Vehicles for 10 years, here is what I know about
VIN #'s. 1981 and some 1982 vehicles had the standard
9-10 digit VIN, from mid 1982 to current a 17 digit VIN #
system was adopted.
To answer your ? about finding the year of a vehicle from a VIN #,
look at the 10th character (usually a letter), and that will tell
you the year, I believe they recycle them, so if the 10th character
is an "M", the vehicle is a 1991 model. I have heard that the VIN is
printed in several different places on the engine block.
If you are lucky enough to obtain a copy of a NICB VIN maual, you
can use that to assist in the reading of VIN #'s.
Here is another site that you should be able to access your VIN
and get all the info vin number search - Vehicle Identification Number Library
How to read a VIN:
VIN # JH4NA1157MT001832
Identifies the country in which the vehicle was manufactured.
For example: U.S.A.(1or 4), Canada(2), Mexico(3), Japan(J), Korea(K), England(S), Germany(W), Italy(Z)
Identifies the manufacturer. For example; Audi(A),
BMW(B), Buick(4), Cadillac(6), Chevrolet(1), Chrysler(C), Dodge(B),
Ford(F), GM Canada(7), General Motors(G), Honda(H), Jaquar(A), Lincoln(L), Mercedes Benz(D), Mercury(M), Nissan(N), Oldsmobile(3), Pontiac(2or5), Plymouth(P), Saturn(8), Toyota(T), VW(V), Volvo(V).
- Identifies vehicle type or manufacturing division.
4th to 8th characters- VDS - Vehicle Descriptor Section.
These 5 characters occupy positions 4 through 8 of the VIN and may be used by the manufacturer to identify attributes of the vehicle. Identifies vehicle features such as body style, engine type, model, series, etc.
- The check digit "character or digit 9" in the sequence of a vehicle identification number (VIN) built beginning with model year 1981 (when the 17 character digit format was established) can best be described as identifying the VIN accuracy. A check digit shall be part of each vin (since 1981) and shall appear in position nine (9) of the VIN on the vehicle and on any transfer documents containing the vin prepared by the manufacturer to be given to the first owner for purposes other than resale. Thus, the vins of any two vehicles manufactured within a 30 year period shall not be identical. The check digit means a single number or letter "x" used to verify the accuracy of the transcription of the vehicle identification number.
After all other characters in the VIN have been determined by the manufacturer the check digit is calculated by carrying out a mathematical computation specified. This is based on vin position, sample vin, assigned value code, weight factor and multiply assigned value times weight factors. The values are added and the total is divided by 11. The remainder is the check digit number. The correct numeric remainder - zero through nine (0-9) will appear. However, if the remainder is 10 the letter "X" is used to designate the check digit value/number.
10th character- Identifies the 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)
Identifies the assembly plant for the vehicle.
12th to 17th characters- VIS - Vehicle Identifier Section.
The last 8 characters of the VIN are used for the identification a of specific vehicle. The last four characters shall always be numeric. Identifies the sequence of the vehicle for production as it rolled off the manufacturers assembly line.
Hope this helps
