International vehicle registration code

Imagine you have a toy car that you want to take on a trip to another country. You want to show your car to all your friends there, but you don't want to get in trouble with the grown-ups.

So, to make sure your toy car is allowed to be in that country, and to make sure everyone knows where it comes from, you need a special code on it. This code is called the international vehicle registration code.

The code is made up of two or three letters, like "USA" for the United States of America or "GER" for Germany. Different countries have different codes, and they use them to identify where a car is from.

When you travel to another country with your toy car, the people at the border will ask to see the code on your car. They will use it to check that your car is allowed in that country and to see if there are any rules you need to follow.

So, the international vehicle registration code is like a special code for toy cars (and real cars, too!) that tells everyone where the car is from and makes sure it's allowed to be there.
