legal advice

Have you ever had a suspicious car that parked on your street that you wanted to trace the license plate on to see who it belonged to? Or maybe you have a new employee starting to work for you and you need to trace his or her license tag number as part of a driving records background check. No matter the reason, there are many people who want to conduct reverse license tag searches everyday.
Before you get started, you should know that there is no free reverse license tag search or lookup database available online or offline. About the only way you can get license tags searched for free is to have a police officer do it for you. Unless you have a good reason or a personal relationship, that's not likely to happen.
There are, however, other ways that you can accomplish your goal of getting owner information from a license tag number. You can contact a private investigator, pay for a search online with a public records database or hire an online firm to conduct your search. Those are about the only options.
License tag numbers are protected information under the Driver's Privacy Protection Act (or DPPA for short). Under this guideline, you can only order a license tag search if you meet certain search exceptions to the rule. For a complete listing of the exceptions to the DPPA, simply visit http://www.accessreports.com/statutes/DPPA1.htm.
In summary, if you need to conduct a reverse license tag search, you will need to have a valid DPPA approved reason to do so. If you do meet this exception, you can either:
Hire a licensed private investigator to conduct your license tag owner search
Pay an online firm to conduct the search for you.
Conduct your own search using public record database membership services
Request a law enforcement agent do the search for you
