If it is a business, the name of the business will appear. This will also usually include the address. Address information will generally consist of a street address as well as the city and state.

Occasionally a number is unlisted, or a listing will appear with no owner information. In this case, often the carrier's name is the only information provided. This will be the name of the phone company that owns that number. If you cannot trace a fax number through one online directory you might try another. Occasionally one has information that is not available on another.
