A person's driver's license number is printed on his driver's license. The exact location of the number on the driver's license varies depending on the state in which the license is issued.
If a person loses his driver's license, he should contact the appropriate state department, such as the Department of Motor Vehicles or Secretary of State, to find out how to get a replacement. If the driver's license is stolen and the person wishes to change his driver's license number, he generally will need to file a police report. Most states charge a fee to replace a lost or stolen license.
