When a new car or a used car is purchased, the first things we notice and enquire about are the design, model, features, colour, engine capacity, and mileage, but what we forget to check is the engine number and the chassis or VIN number (also called Vehicle Identification Number).

Why are the engine and VIN numbers equally important? While purchasing a new or a used car from a dealer it’s difficult to tell whether it’s a one-year-old or six-month-old car that has been sold. This is when the engine and the VIN are important as it is a unique identification number of a car. The 17-digit VIN is unique for every car and helps identify the manufacturer, when it was manufactured, and other details. There will never be two similar VINs. But it is a challenge to find out where these numbers are on the car. Thus, it is necessary to know about car identifiers. Read on to find out how to locate the VIN and the engine number, and what each character signifies.

What do 17-digits in Vehicle Identification Number (VIN) signify?

There are 17 characters in the VIN and each character signifies particular information, and these digits are standard for all vehicles and manufacturers. What each number and character represent is described below – 

First Three Digits

The first digit in the VIN represents the country in which the vehicle is built. The first character could be a digit or a couple of alphabets or a combination of both. For instance, in India, if any vehicle is built, the VIN will start from MA-ME and MZ. The second and third digits provide details of the manufacturer. 

The combination of the first three characters is known as WMI (World Manufacturer Identifier) which tells about the manufacturer of the vehicle. In certain cases, the third character can also denote the manufacturer and also in some cases the type of vehicle. The first three letters also signify the division of the manufacturer in which the vehicle was made. 

Fourth to Eighth Digits

These denote the car’s brand, model, body type, engine type, engine capacity, and fuel type of the vehicle. In the VIN the eighth position is specifically used for denoting the type of engine of the vehicle.

Ninth Digit

The ninth character or digit denotes the security code given by the manufacturer or in some cases also denotes the month in which the car was manufactured.

Tenth Digit

The Tenth character or digit symbolises the year of manufacture of the vehicle. It is represented by an alphabet, allocated to each respective year since 1981.

Eleventh Digit

This character symbolises the manufacturing plant of the vehicle model. 

Remaining Six Digits

The remaining six digits are known as the unique serial number which acts as the next important detail of vehicle identification.
