What is a Vehicle Identification Number and where to find VIN number on car?

Ever spotted a long string of numbers and letters on your car and wondered what it means? That's your VIN number-short for Vehicle Identification Number-and it tells the full story of your car.

Every vehicle in the UK has it's 17-character unique identity code stamped into the chassis during manufacturing, and it stays with the car for life. Unlike a registration number, which can change, the VIN is permanent and can't be altered. It's like your car's fingerprint.

The VIN reveals key details like where the car was built, who made it, what features it has, and more. It's incredibly useful when buying or selling a car, checking for past damage, or confirming the car's identity.

While people often say, "VIN number" (even though the 'N' already stands for number-just like 'PIN number'), it's become a common and widely understood term.

So, whether you're checking a used car or simply curious about your own, understanding the vehicle identification number is a smart move.

In this blog, we'll explain what a VIN number is, what it looks like, where to find it, why it's important, and how to check it-especially if you're in the UK.

What is a VIN Number?

A VIN number, short for Vehicle Identification Number is a unique 17-character code given to every vehicle at the time of manufacture. It acts like your car's fingerprint, containing specific details about the vehicle such as its make, model, year of production, engine type, and where it was built.

This code isn't just a random combination of letters and numbers. Each section of the VIN has a purpose and helps identify the car's origin and specifications. That's why it's such a vital tool for verifying a vehicle's identity, especially when buying or selling a used car in the UK.

The VIN is often used to:

You can usually find your vehicle identification number on the dashboard (near the windscreen) or on a label inside the driver's door frame.

In short, the VIN number gives you a reliable way to check a car's true background before making any big decisions.

What Does a VIN Number Look Like?

A standard VIN number is a 17-character string that includes both letters and numbers (excluding I, O, and Q to avoid confusion with 1 and 0).

Example of a VIN number:

Each part of the VIN carries specific meaning:

Why Should You Check Your Vehicle Identification Number?

Checking a car's Vehicle Identification Number (VIN) is one of the most reliable ways to confirm its identity especially when buying a used vehicle. Since the VIN is permanently assigned during manufacturing, it acts as a complete record of the car's life, no matter how many times it's sold, re-registered, or moved between countries.

By running a VIN number check, you can uncover valuable information such as:

Vehicle records linked to the VIN are stored digitally by manufacturers and registration authorities, making it easier to spot inconsistencies. If the VIN on the car doesn't match the one on the V5C logbook or appears tampered with, that's a serious red flag-it could indicate cloning, theft, or fraud.

For buyers, checking the vehicle identification number offers peace of mind. And for sellers, it's a way to prove your vehicle is exactly what you say it is.

In short, a quick VIN check can help you avoid expensive mistakes and ensure the vehicle is safe and legal to own.

Where to Find the VIN Number on a Car

You can usually locate the VIN number in multiple places:

When Should You Check a Car's Vehicle Identification Number?

You usually won't need the VIN for everyday maintenance or when selling your car, as most details can be checked using the registration number. But if you're doing a detailed background check-especially when buying a second-hand vehicle-a VIN check can reveal more. Reports from official sources can include vital information like accident history, previous write-offs, outstanding finance, and more.

It's especially important to check the VIN number when buying a used car. Always make sure the VIN printed on the V5C logbook matches the number stamped into the car's chassis and any plates on the vehicle. If the numbers don't match, it could be a sign the car has been cloned or tampered with, and it's best to walk away.

Manufacturers also use the vehicle identification number to issue recall notices, so knowing your VIN helps keep your car safe and up to date. Even if it's not something you use daily, knowing where to find your VIN and understanding what it means can help you avoid costly mistakes and make smarter decisions when buying or selling a car.

What Should You Do If the VIN Number on the Car is Different from the Logbook?

If the car VIN number doesn't match the one listed in the V5C or MOT record:

This mismatch could indicate VIN cloning, theft, or major frame repairs. Always ensure the car chassis number, VIN plate, and documents align.
