The White Pages, PeopleSmart and AnyWho are among reliable directories for street addresses in the United States as of 2016. These sites provide extensive online directories and are free to use.
Both first and last names are required to perform an address search at the White Pages site, and providing a city and state aids in narrowing search results. The website also provides reverse address and phone number searches. This database contains over 300 million contacts.
AnyWho offers address lookups using just a last name. The database is updated on a weekly basis. Maps are available to provide directions to and from specific locations.
