What is WMI (World Manufacturer Identifier) Registration?
The World Manufacturer Identifier (WMI) is the first 3-character section of the mandatory 17-digit Vehicle Identification Number (VIN) or Chassis Number standardized globally by ISO 3780 and nationally in India under IS 10278. In India, the Bureau of Indian Standards (BIS) is the sole designated national organization responsible for issuing WMI codes in coordination with the International Agency (SAE International).
Any manufacturer intending to produce motor vehicles (2-wheelers, 3-wheelers, 4-wheelers, electric vehicles, commercial trucks, buses, agricultural tractors, or trailers) must acquire a WMI code before obtaining homologation / Type Approval (TAC) from testing agencies like ARAI or ICAT under the Central Motor Vehicles Rules (CMVR).
Essential for EV Startups
Mandatory first step for Electric Two-Wheeler (E2W), E-Rickshaw, and Electric Three-Wheeler OEMs prior to ARAI/ICAT testing.
Permanent Unique Identity
WMI uniquely identifies the country of origin (India - 'MA-ME', 'MZ') and the manufacturer across all global automotive databases.
