Comercial Telephone Book

A telephone directory (also known as a telephone book, phone book, or white/yellow pages) is a listing of telephone subscribers in a geographical area or subscribers to services provided by the organization that publishes the directory. Its purpose is to allow the telephone number of a subscriber identified by name and address to be found.

The rise of the Internet and smart phones in the 21st Century greatly reduced the need for a paper phone book.

Content

Subscriber names are generally listed in alphabetical order, together with their postal or street address and telephone number.

A telephone directory may also provide instructions about how to use the telephone service in the local area, may give important numbers for emergency services, utilities, hospitals, doctors, and organizations who can provide support in times of crisis.

Types

Other colors may have other meanings; for example, information on government agencies is often printed on blue pages or green pages.
