There are several options to look up a business phone number, including sites like Yellowbook, Whitepages and phone providers like AT&T. These sites offer look-up services that allow users to find a business by name, category, location or a combination of these.
These sites offer services for free and allow the user to access phone numbers in area outside of those they live in. Traditional paper phone books only offer listings for the county that someone resides in, making calls to 411 an added step in some cases. Using sites like Yellowbook saves users time and avoids the fees sometimes related to making information calls.
