WMI (World Manufacturer Identifier) Code Registration

WMI (World Manufacturer Identifier) Code Registration

Global Vehicle Identification for Indian Automobile Manufacturers

Introduction to WMI Code

The World Manufacturer Identifier (WMI) Code is an internationally recognized identification code issued to automobile manufacturers for global vehicle identification. In India, the Bureau of Indian Standards (BIS)—a member of the International Organization for Standardization (ISO)—facilitates the assignment of WMI codes to Indian vehicle manufacturers.

The WMI code forms the first three characters of the Vehicle Identification Number (VIN), also known as the chassis number. Along with other VIN elements, the WMI ensures that every vehicle manufactured anywhere in the world has a unique identification number.

In coordination with SAE International (Society of Automotive Engineers), USA, and the ISO framework, BIS assigns WMI codes through its International Relations and Technical Information Services Division.

What is a Vehicle Identification Number (VIN)?

A Vehicle Identification Number (VIN) is a 17-character alphanumeric code used globally to uniquely identify motor vehicles. Before 1980, VIN formats varied by manufacturer, but standardization was later achieved through ISO regulations.

Key Standards Governing VIN
  • ISO 3779 – Structure and content of VIN
  • ISO 3780 – World Manufacturer Identifier (WMI)

To avoid confusion, the letters I, O, and Q are not used in VINs.

VIN standards are accepted globally, including by:

  • European Union
  • United States of America
  • Other international automotive markets

Applicability of VIN & WMI (As per ISO 3833)

VIN and WMI requirements apply to:

  • Motor Vehicles
  • Trailers
  • Motorcycles
  • Mopeds

Who is a Manufacturer?

A manufacturer is defined as any individual, company, or organization responsible for assembling a vehicle into a complete and operational unit. The manufacturer is responsible for ensuring VIN uniqueness for every vehicle produced.

World Manufacturer Identifier (WMI) Code Explained

The WMI Code:

  • Occupies the first three characters of the VIN
  • Identifies the country, manufacturer, and manufacturing division
  • Can consist of letters and digits
WMI Registration Authority
  • SAE International (USA) is the global WMI registration authority
  • BIS coordinates WMI assignment for Indian manufacturers and registers the code with SAE

The first character of the WMI identifies the manufacturing country.

Structure of the VIN

Vehicle Descriptor Section (VDS)
  • 4th to 9th characters of VIN
  • Describes:
    • Vehicle type
    • Model
    • Body style
    • Platform
    • Engine type (in some cases)

Manufacturers may define this section as per their internal coding system, while remaining compliant with ISO standards.

Vehicle Identifier Section (VIS)

Model Year Code
  • 10th character of VIN
  • Identifies the vehicle model year
  • Letters U, Z, and digit 0 are not used
  • Excludes I, O, Q (as per VIN restrictions)
Plant Code
  • 11th character of VIN
  • Represents the manufacturing plant
  • Plant codes are manufacturer-specific but position is standardized

Procedure for WMI Code Registration in India

The WMI registration process involves the following steps:

1. Application Submission
  • Submission of application with supporting documents to BIS
2. Document Verification
  • BIS verifies technical, legal, and manufacturing details
3. WMI Code Proposal
  • BIS proposes WMI code based on available series
  • Entry of proposed WMI in BIS database
4. Registration with SAE International (USA)
  • BIS forwards the proposal to SAE International
5. Confirmation from SAE
  • SAE issues official confirmation of WMI registration
6. Notification to Applicant
  • BIS communicates WMI allocation to the manufacturer

Eligibility & Conditions for WMI Code Assignment

Applicants must submit the following:

  • Name, address, and location of manufacturing facility
  • Memorandum & Articles of Association (MoA & AoA)
  • Industrial License for automotive manufacturing (certified copy)
  • Installed capacity & annual production details (model-wise)
  • Technical specifications and brand details
  • Existing vehicle coding system (if any)
  • Business size (small / medium / large)
  • Detailed VIN structure with drawings (as per ISO 3779 / 3780 / 4030)

Importance of WMI Code Registration

  • Mandatory for global vehicle identification
  • Enables international vehicle traceability
  • Required for export & international sales
  • Ensures compliance with ISO & SAE standards
  • Strengthens manufacturer credibility

Without a valid WMI code, manufacturers cannot generate internationally accepted VINs.
