Reverse License Plate Lookup
More recently than ever, finding out people's information from their license plate has become harder and harder, mainly down to privacy laws and policy shifts in the federal government. Because of this, it is now pretty difficult to find the owner of a license plate publicly (I am sure the police have a tool which can see who owns them).
The best way to find out who owns a license plate is definitely to either use a private detective firm or call the DMV and request the records. Both of these services will carry a fee and both will not "guaranteed" or set in stone.
To find the details yourself online, you will either have to search the likes of the Google, Yahoo & MSN but the chances of a "hit" or very unlikely indeed. Alternatively, you could use the Gov-Records system below to find out if they have the records in their huge database of millions of people.
