What is the Chassis & VIN number on the Bike? How to Find it?

Many of us own a two-wheeler and know little about its important elements! Each vehicle is assigned a chassis and engine number to identify its owner in case the bike gets stolen or goes missing. When the need for vehicle identification arises, these two numbers play a major role in the entire process. 

Even though the chassis can help you recognize the missing bike, most robbed vehicles are never located. But owners of 2-wheelers with valid insurance can be reimbursed for losses in that case. This is why it’s recommended to have proper insurance that can help you in uncertain times.

Having an Ontrack comprehensive bike insurance policy can save you from losses with compensation as per the Insured Declared Value(IDV). 

To help you understand what chassis and VINs mean, here is a detailed explanation.

Use our  Ontrack App to search for RTO vehicle Information and information on bike.

What is Chassis Number and where to find it for the bike?

There are six characters representing it in the last six characters of the VIN. This is why chassis number and VIN are often treated as similar terms.

The chassis number of your vehicle can also be found by looking at the VIN! 

The chassis number as the name suggests can be easily found on your bike’s chassis. You can search for it on the VIN.

If you need another way of finding the chassis number, then search for it in the owner’s manual or your two-wheeler’s registration certificate.

Components of Chassis number:

  • World Manufacturer Identifier (WMI)
  • Vehicle Description Section (VDS)
  • 9 other characters indicating the type of vehicle, its displacement, engine type, design sequence, vehicle version, accuracy check digit, year of manufacture, and plant code
  • Serial number of the vehicle

On the two-wheeler handlebars or engine, you will find the chassis number. It may be difficult to locate the chassis number on your bike without assistance from a mechanic. It is common to refer to the bike’s chassis number in the owner’s manual and on the registration certificate.

Vehicle Identification Number(VIN):

An identification number for a vehicle is referred to as a bike VIN. This is a unique 17-character code. They contain the letters and numbers used to identify a vehicle. 

Neither commercial nor private vehicles are exempt from this requirement. Several details about your bike are provided by this number, such as:

  • The place where it was produced
  • Description of vehicle
  • Identification of vehicle
  • The year when it was made
  • Location of RTO (Regional Transport Office)
  • Two wheeler insurance

These are located on the steering column of the bike. Some bikes have it on the motor and not on the steering necks. Make sure to check for the model and the dealer, in case you didn’t find it there.

A national register e-service called VAHAN was developed by the government with the advancement of technology. The website provides information about vehicles as well as other analytical data. 

One can find both the numbers i.e the engine number of the vehicle and the chassis number on the official portal mentioned above. Such important information is available on the VAHAN website to authorized institutions such as insurance companies and banks.

Your bike’s VIN/Chassis number will be embossed on the frame of the vehicle which is also called a chassis. It will also be on the registration certificate. 

Components of the VIN:

17 characters make up the VIN, as mentioned above. To categorize this serial code, we can divide it into the following three parts.

  1. World Manufacturer Identifier:

A VIN’s first three characters fall under this category. Alternatively, it is called the WMI code. Using these characters, you can find out who made the vehicle and where it was made.

  1. Vehicle Descriptor Section:

There are nine characters in the Vehicle Descriptor Section. A vehicle’s characteristics are determined by these characters, as the name suggests.

  1. Vehicle Identifier Section:

The characters in the numbers 16 to 17 form this section. It gives accurate identification to every vehicle with other details about the engine, transmission, and plant code along with the model year.
