Whether your car was involved in a hit-and-run accident that only allowed you to catch the other driver's license plate number or if you've witnessed a crime, locating a driver by license plate number is a relatively simple task. Make sure you've got the correct number before you begin your search.
Call your local police department. If you've been in an accident from which the offending driver fled the scene, police will be able to locate the driver with a description of the car and the license plate number. Make sure you have the full, accurate license plate number, otherwise it could lead to delays in the search for the other driver.
Check the laws in your state. Some states may allow you to search their Department of Motor Vehicles website to find a driver by license plate number. Many states, however, consider this a violation of privacy and do not make the records available to the general public.
Visit a reverse license plate lookup site like Vehicle Data Registry. Enter the plate number to search for information on the vehicle's owner. You pay a small fee with your credit card and then search the database for the information.
Hire a private investigator. In situations where you worry that you or your children are being stalked and/or followed, you may want to hire a private investigator to do the work for you. This can be costly: Services start at about $100, depending on the extensive nature of your search.
