Most people have heard the term “vehicle identification number”, or VIN, but they don’t really know what it is. Yes, they understand that each car has its own number. But, what do those letters and numbers really mean? And, more importantly, why do we have vehicle identification numbers anyway?

In this article, we’ll break down exactly what a vehicle identification number is. We’ll also talk about why these numbers are so important. You’d be surprised at what kind of information these numbers really provide. You may also be surprised at how these numbers can be used.

Where Can You Find a VIN?

If you don’t know where to find the vehicle identification number on your vehicle, you only have to look in one of two places. The obvious place to find the VIN is on the driver’s side of your dashboard. It’s actually stamped on a small plate right near your windshield. But it can also be found stamped on the firewall of your engine. If someone manages to pry the number off your dashboard, the police or your mechanic will be able to find it by looking inside the engine.

What Do the Numbers and Letters on Your VIN Mean?

Most people think that their VIN is just a random combination of letters and numbers. After all, there are millions or billions of combinations of letters and numbers to pick from. Each VIN has 17 separate digits or letters. Each of these has a special meaning.

Can You Change Your Vehicle Identification Number?

Like we said above, your VIN is like your fingerprints. You really can’t change them. You can try to scrape it off or alter it – but why would you want to do this? This is the kind of thing people do when they steal a car. Even then, they probably won’t know to check the engine’s firewall. At some point, the police or DMV will be able to track your vehicle down.

That doesn’t mean that thieves don’t try to do these things. Just like criminals try to change their fingerprints by having their fingertips burned or disfigured, car thieves try to do the same thing with a VIN. They may scrape off some of the letters or numbers, hoping it will prevent the police from identifying the car as stolen. Or, they replace the VIN plate with another one.
Even if this does buy the thief some time, eventually, the police will track down the correct information. They can check the engine’s firewall. Or, they can track down the manufacturer and get the correct VIN. The police have access to a lot of information we don’t have.

Why Would You Want to Change the VIN?

It makes sense that a criminal would want to change or destroy the vehicle identification number. If they’re driving a stolen car, they don’t want the police to be able to see the VIN. The same is true if they want to sell a stolen car. They would need to change the VIN, otherwise, the prospective buyer would be able to look it up and see that it was stolen.

But criminals aren’t the only ones who try to change a VIN. Some people think that, if they change the vehicle identification number, a prospective buyer won’t know the car was involved in a terrible accident. The same can be true if someone simply doesn’t want to pay to register or insure a car. They think if the VIN isn’t apparent to the police or the DMV, they won’t have to worry about fines or tickets.

The best thing to do is never try to change your VIN. It’s there for a reason. 99% of you would never think about changing your vehicle identification number. But, if you were thinking of doing this, don’t bother. It will only make life more difficult for you.
