The BIS authority in India, a member of the International Organization for Standardization, provides this kind of code to Indian automakers for use in worldwide identification. It is the first component of the vehicle identification number (VIN), also known as the chassis number, and along with the other components of the VIN, it guarantees that every vehicle created anywhere in the world has a unique VIN. This code may be made up of both letters and digits. In collaboration with the Society of Automotive Engineers Inc., USA, and the worldwide organization in charge of car maintenance, the International Relations and Technical Information Services Division of BIS offers the WMI Code Assignment Service to Indian automobile manufacturers.

Vehicle Identification Number (VIN)

VIN, which is a popular abbreviation for unique serial numbers, is a unique serial number used by the automobile industry to identify certain motor vehicles. Because there was no recognized standard for these numbers before 1980, many manufacturers employed various forms for their usage. different formats

The letters I, O, and Q are not present in the current 17-character VINs. The VIN is based on two related standards, ISO 3779 and ISO 3780, which were first published by the International Organization for Standardization (ISO) in 1979 and 1980, respectively. They do not contain the letters I, O, or Q. The relevant but slightly differing implementations of these ISO standards have been approved by the European Union and the United States of America.

This global system of standard identifying numbers for road vehicles establishes the format and information that must be included in the VIN. Road vehicles, VINs, content, and construction are covered by ISO 3779. WMI code is ISO 3780 for road vehicles.
