Telephone Directory Finding the right Telephone Directory

A telephone directory can be used both for individuals and certain companies, agencies, or organizations. For a telephone directory with information on individuals, the best place to look is in the white pages. White pages provide information on a person’s listed name, address, and telephone number. 

This telephone directory is available both in print and online. For a printed telephone directory, the entries are usually regional and only provide numbers that are listed locally. For example, they can be for one or multiple counties.

An online telephone directory can search through a much larger area. Many of them can search by just a last name to find entries from across the country. They can also be searched more specifically by using both a first and last name along with an address, city, state, or zip code.

Another advantage of using an online phone directory is the ability to do a reverse search. Because physical phone directories are organized by last name, it is impossible to find a listing based on a reverse or a phone number. However, an online telephone directory can search through listing when given a phone number, or an address.
