What is a tag number on a car?

A tag number on a car is a unique identification number assigned to the vehicle by the government or a registration agency. It is also known as a license plate number. The tag number contains a combination of letters and numbers that are specific to the state in which the vehicle is registered. It is used for identification purposes when the vehicle is operated on public roads, and it helps law enforcement agencies to track down vehicles that have been involved in accidents or other incidents. The tag number is usually displayed on both the front and rear of the vehicle and must be visible at all times. It is important to keep the tag number up to date and renew it annually to avoid fines or penalties.
