Telephone Directory Pencil Drawing

A telephone directory (also called a telephone book and phone book) is a listing of telephone subscribers in a geographical area or subscribers to services provided by the organization that publishes the directory. Subscriber names are generally listed in alphabetical order, together with their postal or street address and telephone number. Every subscriber in the geographical coverage area is usually listed, but subscribers may request the exclusion of their number from the directory, often for a fee. Their number is then said to be "unlisted" (American English), "ex-directory" (British English) or "private" (Australia and New Zealand).
