Vehicle Identification Number (VIN)

What is it? A car’s vehicle identification number (VIN) is the automotive equivalent of human "DNA". It sets the vehicle apart from the millions of other vehicles out there. In recent times it has been reflected in 17 digit characters. It displays a car’s uniqueness and heritage and provides a form of "factory to scrapyard" identification. It can be used to track recalls, registrations, warranty claims, thefts and insurance coverage. Each character or digit has a particular purpose.

History of the VIN Detroit automobile manufacturers began stamping and casting identifying numbers on cars andtheir parts in the mid 1950's . The primary purpose of this vehicle identification number (VIN) was to give an accurate description of the vehicle when mass production numbers were starting to scale in very significant numbers. The early VINs came in a range of variations depending on the individual manufacturer at that time. In the early 1980's the U.S. National highway Traffic SafetyAdministration (USDOT) required that all road vehicles must contain a 17 character VIN. This established the standard fixed VIN system which major vehicle manufacturers use currently. The result was a unique "DNA" style number for each individual vehicle rolled off the assembly line. The Vehicle Identification Number was originally described in ISO Standard 3779 in February 1977 and last revised in 1983. TheISO-VIN was designed to identify motor vehicles, trailers, motorcycles and mopeds and consists of several parts described below.

How to read a VIN 1st character- 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) 2nd character- 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). 3rd character-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.

(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 thevehicle 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 othercharacters 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 -...
