Which sources are considered the most common for vehicle and owner information?

The most common sources for vehicle and owner information are license tags and VIN (Vehicle Identification Number). The license tag provides a unique identifier for the vehicle as it is registered with the state, allowing law enforcement and other entities to quickly access vehicle registration details. The VIN serves a similar purpose, as it is a unique code assigned to every vehicle, containing essential information about its make, model, and production year. Together, these elements are critical for identifying both the vehicle and its registered owner in various databases, such as those maintained by the Department of Motor Vehicles (DMV) and law enforcement agencies.

While other options may contain some relevant information, they do not serve as primary identification sources for vehicles in the same systematic way as the license tag and VIN.
