WMI Registration Vehicle Manufacturer in India: Complete Guide

• WMI registration vehicle manufacturer is the process of obtaining a World Manufacturer Identifier used to identify a vehicle manufacturer within the Vehicle Identification Number (VIN).
• The WMI forms the first section of a vehicle’s VIN and is an important part of vehicle identification, traceability and type-approval documentation.
• Vehicle manufacturers should address WMI requirements early because WMI information is also required in the documentation submitted during CMVR vehicle type approval.

Introduction

A new electric-vehicle manufacturer can have a production line ready, a prototype tested and a sales strategy in place, yet still discover that an important identification requirement has not been addressed.

A manufacturer may initially focus on battery specifications, motor performance, braking, lighting, EMC, safety components and vehicle testing. The identification system of the vehicle is treated as a later administrative task. By the time the company reaches type-approval documentation, the WMI information becomes necessary.

WMI stands for World Manufacturer Identifier. It is the first section of a Vehicle Identification Number, or VIN, and identifies the vehicle manufacturer. Under AIS-065, the VIN consists of three sections: the World Manufacturer Identifier (WMI), Vehicle Descriptor Section (VDS) and Vehicle Indicator Section (VIS).

What Is WMI Registration for a Vehicle Manufacturer

WMI registration refers to obtaining a manufacturer-identification code used as part of the VIN assigned to vehicles.

WMI means World Manufacturer Identifier

The first three characters of the VIN form the WMI section. AIS-065 explains that the WMI is a three-character code assigned to identify the vehicle manufacturer. Its first character represents a geographical area, the second represents a country within that geographical area and the third identifies the specific manufacturer.

In simple terms:

• WMI identifies the manufacturer.
• VDS describes general vehicle characteristics.
• VIS identifies the individual vehicle and its production-related information.
• This structure gives every vehicle a consistent identification framework.

Why Is WMI Important for Vehicle Manufacturers

A vehicle needs more than a brand name and model name to be uniquely identifiable.

Consider a manufacturer producing several thousand electric scooters. The company may have multiple variants, production batches and manufacturing dates. A structured VIN provides a consistent identity for each individual vehicle.

The WMI establishes the manufacturer’s identity at the beginning of that identification number.

It is relevant to:

• Vehicle identification
• VIN generation
• Manufacturing traceability
• Type-approval documentation
• Chassis identification
• Production records
• Vehicle registration processes
• Compliance documentation
• Recall and after-sales traceability

The Automotive Research Association of India (ARAI) also identifies WMI/WMC documentation as part of the documentation associated with vehicle type approval.

What Does WMI Stand For

WMI stands for World Manufacturer Identifier.

It is the first three-character section of a VIN and is used to identify the manufacturer and geographical/country allocation associated with the vehicle.

A vehicle identification number is structured into three principal sections:

VIN section	Meaning	General purpose
WMI	World Manufacturer Identifier	Identifies manufacturer
VDS	Vehicle Descriptor Section	Describes vehicle characteristics
VIS	Vehicle Indicator Section	Identifies individual vehicle/production information

AIS-065 specifies this three-section structure for VIN identification.

Who Needs WMI Registration in India

The requirement should be assessed based on the type of vehicle and the manufacturer’s role.

It is particularly relevant to manufacturers producing vehicles such as:

• Two-wheelers
• Three-wheelers
• Passenger cars
• Commercial vehicles
• Buses
• Trucks
• Electric vehicles
• Chassis
• Certain trailers
• Special-purpose vehicles
• Other vehicle categories covered by the applicable identification requirements

ARAI’s current vehicle certification information covers two-wheelers, three-wheelers and four-wheelers, including petrol, diesel, CNG, LPG, alternate-fuel and electric vehicles within the relevant categories.

A startup manufacturing electric scooters, for example, should consider WMI as part of its overall homologation and vehicle-identification planning rather than treating it as a separate afterthought.

What Is the VIN Structure

VIN means Vehicle Identification Number.

Under the AIS-065 structure, the VIN consists of:

First Section: WMI

The first three characters identify the manufacturer.

Second Section: VDS

The Vehicle Descriptor Section contains six characters and can be used to indicate general vehicle characteristics. AIS-065 notes that manufacturers may use this section for information such as type designation, version, variant or manufacturing logistics.

Third Section: VIS

The Vehicle Indicator Section provides the remaining characters used for individual vehicle identification and related production information.

The exact coding methodology needs to be established consistently by the manufacturer and aligned with the applicable requirements.

WMI Registration Vehicle Manufacturer: Step-by-Step Process

The exact administrative route can depend on the applicable authority and current procedure. From a compliance-planning perspective, the process can be organised into the following stages.

Step 1: Establish Manufacturer Eligibility

First determine whether the applicant is actually the manufacturer responsible for the vehicle’s type approval and production compliance.

AIS-149’s definition of manufacturer states that the manufacturer is the person or body responsible to the approval authority for all aspects of type approval and conformity of production. It also notes that the manufacturer is generally identified by the WMI.

This distinction matters where manufacturing, branding, assembly and technical responsibility are split between different entities.

Step 2: Identify the Vehicle Category

Determine whether the product is a:

• Two-wheeler
• Three-wheeler
• Passenger vehicle
• Commercial vehicle
• Bus
• Truck
• Chassis
• Other applicable vehicle category

The category determines the technical standards and type-approval requirements that follow.

Step 3: Prepare Manufacturer Details

Compile the legal and manufacturing information required for the WMI application.

Avoid preparing this separately from your homologation file. The same company and plant information will often appear in multiple regulatory documents.

Step 4: Establish the VIN Structure

The manufacturer needs to understand how the WMI will be incorporated into the VIN.

The VDS and VIS portions also need to be planned consistently.

This is particularly important when the company has multiple models or variants.

Step 5: Submit the WMI Application

The application and supporting information are submitted through the applicable process.

The responsible authority reviews the information and may seek clarification or additional documents.

Step 6: Address Queries

If the reviewing authority raises a query, respond with documents and explanations that are consistent with the original application.

Unclear company structures or inconsistent manufacturer names are common sources of avoidable clarification.

Step 7: Obtain the WMI Allocation

Once approved, the manufacturer receives the applicable WMI identification.

The code then becomes an important element of the manufacturer’s VIN structure.

Step 8: Use the WMI Correctly

The manufacturer should ensure that VIN generation, marking, documentation and production systems use the approved identification consistently.

The WMI should not be treated as an isolated certificate that sits in the compliance folder.

It becomes part of the vehicle’s identity.

What Documents Are Required for WMI Registration

A practical document file may include:

Document / Information	Purpose
Certificate of incorporation	Establishes legal identity
Company PAN	Corporate identification
GST details	Business identification where applicable
Manufacturing plant details	Establishes production location
Authorised signatory details	Supports application authority
Vehicle/product information	Identifies manufacturing activity
Technical information	Supports vehicle identification and approval planning
Existing approval information	Helps establish regulatory status
Manufacturer declaration	Supports application particulars
Supporting corporate documents	Verifies applicant information

This should be treated as a working checklist rather than a universal statutory list. The exact documents should be confirmed against the current WMI application requirements.

Common Mistakes in WMI Registration

Applying Without Understanding the Manufacturer Structure

If one company owns the brand but another entity is responsible for manufacturing and type approval, the WMI applicant needs to be aligned with the actual regulatory responsibility.

Treating WMI as the Final Approval

WMI is not equivalent to vehicle type approval.

Creating VIN Codes Without a Defined Structure

The manufacturer should establish how the VDS and VIS will be used before production begins.

Inconsistent Company Information

Different legal names, addresses or plant details across WMI, type approval and corporate documents can trigger avoidable queries.

Applying Too Late

WMI should be considered before final type-approval documentation and production planning.

Assuming All Vehicles Use the Same Compliance Route

Two-wheelers, three-wheelers, passenger vehicles, buses and commercial vehicles can have different regulatory requirements.

How Diligence Certifications Can Help Vehicle Manufacturers

For a new automotive business, WMI rarely exists as a standalone compliance task.

It normally sits within a broader sequence involving:

Manufacturer setup → WMI → VIN planning → component compliance → prototype → testing → type approval → CoP → vehicle registration

Diligence Certifications can assist businesses in navigating certification and regulatory requirements and can help manufacturers understand where WMI fits within their overall automotive compliance strategy.

For manufacturers working on vehicle certification, it is useful to review the Diligence Certifications services page for the wider range of compliance support available.

Manufacturers can also coordinate WMI requirements with related ARAI certification and automotive compliance support, where applicable.

The objective should not simply be to obtain a WMI code. The objective is to create a compliance file in which the company identity, WMI, VIN structure, technical specifications and type-approval records all tell the same story.

---

Conclusion

WMI registration vehicle manufacturer requirements are an important part of the compliance architecture for manufacturers that need structured vehicle identification.

WMI is not the same as ARAI type approval, and it does not by itself authorise a vehicle for sale or road use. Its purpose is more specific: it identifies the manufacturer within the VIN structure and supports vehicle traceability and regulatory documentation.

For a new Indian automobile or EV manufacturer, the sensible approach is to address WMI early, establish the VIN structure correctly and align the information with the company’s type-approval and production records.

Diligence Certifications can help manufacturers understand the WMI requirement, organise the supporting documentation and coordinate it with the wider vehicle certification process.
