---GB/T 16737-1997, GB 16737-2004. Road Vehicle - World Manufacturer Identifier (WMI) Code

1 Scope

China's mandatory national standard for the world manufacturer identifier. The WMI is the first three characters of every vehicle identification number, and it says who built the vehicle and where - the first character the geographic area, the second the country, the third the manufacturer. It is allocated rather than chosen: a national body assigns codes within the ranges the international system reserves for it, and this standard is the Chinese instrument for doing that. What makes it consequential is that the WMI is the anchor of the whole identification chain: a safety recall is issued against a range of VINs, and the WMI is what tells a registration authority in another country which manufacturer is responsible. The standard specifies the structure of the identifier, the rules for its allocation, and the requirements a manufacturer must meet to be assigned one.

This Standard stipulates the content and structure of world manufacturer identifier (WMI) code. World manufacturer identifier (WMI) code is the first part of vehicle identification number (VIN) described in GB 16735. This Standard is applicable to automobile, and its incomplete vehicle, trailer, motorcycle and moped. Other vehicles that need vehicle identification number may also take this as a reference.
