A license plate identifies a registration rather than a vehicle. That distinction matters, because in many states plates stay with the owner when a vehicle is sold, and in others they stay with the vehicle.
Because plates can be reassigned, surrendered or transferred, the link between a plate and a particular vehicle is a point-in-time fact rather than a permanent one. A plate lookup resolves to the vehicle currently registered to it.
Access to the personal information behind a registration is restricted by federal privacy law, so a plate search returns vehicle details rather than owner details.
Why it matters
A plate is often all you have before contacting a seller, and it is enough to confirm that the vehicle being advertised matches the vehicle actually registered.
How to check it
Resolve the plate to a VIN, then run the history against the VIN. The plate is a starting point rather than the thing you check.
Does this apply to the car you are looking at?
Run the VIN or plate and see what is actually on record.

Definitions are general guidance, not legal advice. Title rules, total loss thresholds and inspection requirements are set by each state and change over time, so confirm the position with the motor vehicle agency for the state the vehicle is titled in before relying on it.
