How to Find Bike Chassis Number and Engine Number

If you own a two-wheeler in India, knowing your bike’s chassis number and engine number is extremely important. The chassis number acts as the permanent identity of your vehicle and helps authorities, insurers, and service providers accurately identify your bike. These unique identification numbers are required for multiple purposes, including insurance purchase and renewal, RC verification, claim filing, theft reporting, and resale of the vehicle. Without correct chassis and engine details, important processes such as buying insurance or transferring ownership can get delayed or even rejected.

Despite their importance, many bike owners are unsure where to locate the chassis number on their vehicle or why it matters so much. This lack of awareness can lead to errors while entering details online, resulting in policy discrepancies or claim complications. Understanding where to find your bike’s chassis number and ensuring it matches your RC and insurance documents helps you stay legally compliant, protects you from fraud, and ensures smooth insurance and ownership-related processes throughout the life of your two-wheeler.

What Is a Bike Chassis Number?

The chassis number (also called VIN – Vehicle Identification Number) is a unique alphanumeric code assigned by the manufacturer to identify your bike’s frame. No two bikes have the same chassis number. It acts as your vehicle’s identity throughout its lifetime.

Why Is the Chassis Number Important?

·       Mandatory for bike insurance

·       Required for RC verification

·       Used during claim settlement

·       Helps trace stolen vehicles

·       Essential during resale or ownership transfer

What Is a Bike Engine Number?

The engine number is another unique number engraved on the bike’s engine block. It identifies the engine installed in your vehicle and is recorded during registration.

Why Is the Engine Number Important?

·       Confirms engine authenticity

·       Required during insurance documentation

·       Needed for RTO processes

·       Helps in servicing and spare part verification

Where to Find Bike Chassis Number and Engine Number

1. On the Bike Itself (Physical Inspection)

Most manufacturers engrave these numbers at specific locations:

·       Chassis Number:

o   Near the steering neck

o   Under the seat

o   On the frame below the fuel tank

·       Engine Number:

o   On the engine crankcase

o   Side of the engine block

Tip: Clean the area properly to read the number clearly.

2. In the Registration Certificate (RC)

Your RC book or smart RC card mentions both:

·       Chassis Number

·       Engine Number

This is one of the most reliable and legally accepted sources.

3. In Your Bike Insurance Policy Document

Bike insurance policies clearly mention:

·       Vehicle chassis number

·       Engine number

This is especially useful if you don’t have immediate access to your bike.

4. Through the VAHAN Portal (Online)

You can check your vehicle details online via the Parivahan VAHAN portal using your registration number. It displays:

·       Chassis number (partially masked)

·       Engine number (partially masked)

·       Registration details

This method is useful for verification purposes.

5. Invoice or Delivery Receipt

If your bike is new, the dealer invoice or delivery challan will include both numbers. Always keep this document safe.

How to Verify Chassis and Engine Numbers

Verification is crucial to avoid fraud or documentation issues:

·       Ensure numbers match across RC, insurance, and bike

·       Check spelling and digit accuracy

·       Immediately report mismatches to the insurer or RTO

Incorrect numbers can lead to claim rejection or legal issues.

Why Insurers Ask for Chassis and Engine Numbers

Insurance companies use these numbers to:

·       Identify the insured vehicle

·       Prevent duplicate or fake policies

·       Validate claims

·       Ensure accurate policy issuance

Even a small error can delay policy approval or claim settlement.

Common Mistakes to Avoid

·       Entering wrong digits while buying insurance online

·       Confusing engine number with chassis number

·       Using unofficial sources for verification

·       Ignoring mismatches between RC and policy documents

Always double-check before submitting details.

Bike Chassis Number vs Engine Number: Key Differences

The chassis number and engine number serve different but equally important purposes in identifying a bike. The chassis number uniquely identifies the vehicle’s frame and remains unchanged throughout the bike’s lifetime, making it a permanent identity of the two-wheeler. In contrast, the engine number identifies the engine unit installed in the bike and can change if the engine is replaced due to damage or upgrades. Both the chassis number and engine number are clearly mentioned in the Registration Certificate (RC) and are essential for legal verification. Additionally, both numbers are mandatory for bike insurance, as insurers use them to accurately identify the vehicle, issue policies, and process claims without discrepancies.

Importance During Insurance Claims

During claims, insurers verify:

·       Chassis number

·       Engine number

·       RC details

Any discrepancy may result in claim delay or rejection, making accuracy essential.

Conclusion

Knowing how to find your bike chassis number and engine number is not just technical knowledge—it’s a vital part of responsible vehicle ownership. These numbers protect you legally, simplify insurance processes, and ensure smooth transactions during resale or claims.

Always keep your RC, insurance policy, and purchase invoice safe and updated.
