How Is VIN Vehicle Number Formed
The vehicle Identification number (VIN - Vehicle Identification Number) is a unique code that encrypts information about who, when, where and in what configuration issued the car.
Such signals were not needed immediately, but only when the number of cars produced began to reach millions. At first, in the mid-50s, they tried to restore order in the United States, but there was no single standard, and each manufacturer encrypted VIN codes in its own way.

only 30 years later, in the early 80s, the National Association of traffic Safet SAF in the United States will oblige all new cars to be marked with a 17-digit identification number. This will be the starting point for restoring order.
40 years have passed since the introduction of the standard for VIN codes, but the general principles of its formation have not changed. Initially the ISO 3779:1983 standard was used, later it was replaced by ISO 3779:2009 (current), now the development of its successor ISO/A A
the structure of the VIN code
the structure, sections, allowed symbols and recommendations for the formation of the VIN code of the vehicle are described in ISO 3779:2009. The symbols used in the VIN code are a list of letters of the Latin alphabet and Arabic numerals allowed for use in the vehicle identification number: 0 1 2 3 4 5 6 7 8 9 A B C D E F G H K
it is forbidden to use three letters of the Latin alphabet to form a VIN number, since they are similar to each other in spelling or Arabic numerals. We are talking about I (similar to 1), O (similar to 0 and Q), Q (similar to 0 and o). The vehicle identification number consists of 3 parts and contains the following information (VIN lookup for reference):
- id mid (or orld manufacturers Identification) - manufacturer`s index (3 characters); & nbsp;
- VDS (vehicle description section— - descriptive Part (6 characters); & nbsp;
- VIS (Vehicle Identification Section— - distinctive part (8 characters).
WMI
WMI The first symbol indicates the geographical area, the second the country, the third the code of the car manufacturer. A manufacturer can have multiple WMI, but the same WMI can not belong to two different automobile manufacturers (except in cases where the WMI used has not been used for more than 30 years of age, in which case there may be republished, even to a different manufacturer , as well as for factories with a production volume of less than 500 cars per year). Below is the table of Themi I codes that define the country of production (according to the current ISO 3780:2009 standard, see more here VIN check). The principle of formation is as follows: the first letters of the Latin alphabet are used, then Arabic numerals (from 1 to 0). For example, two-digit combinations start with AA and end with A0. Some combinations are spare. Signed combinations & quot;available in the region" they mean that suchmi In the latest standards, they can be assigned to other countries or regions.
large factories received their own three-digit index to identify cars of their own production, small factories (annual output less than 500 vehicles) use the combinations X The latter can be the same for a number of factories, so the distinctive digit-letter combination in the VIN code of the car in this case is written in the third, fourth and fifth characters of the section of the car indicator (VIS), or, in other words, on the 14 - 16 characters of the VIN.
