How do you get someones driver license number to sue?

To obtain someone's driver's license number for legal purposes, you typically need to have a legitimate reason, such as a legal claim or lawsuit. One way to access this information is through a court order or subpoena if you're involved in a legal case. Alternatively, you might contact the local Department of Motor Vehicles (DMV) or equivalent agency, though they usually require a valid reason and may have strict privacy regulations. It's advisable to consult with a legal professional to ensure you're following proper procedures.
