The City, State, and Postal Code searches an outside database for legitimate City, State and Postal Code information. The search dialog box contains three entries, City, State and Zip. The search can be performed with using just one entry or several. Ex. A search for the city 'Hamilton' will return several entries. If the search is performed with the City, Hamilton and the State, OH the results are different. Please be advised we do not guarantee the validity of this data. Please use at your own risk.
