A local telephone directory （电话号码簿） is sometimes called the White Pages. This directory provides an alphabetic (按字母顺序的) listing of names and telephone numbers and other telephone reference information. The front pages usually contain information about area codes; customer service; directory assistance; local, long-distance, and international calls; time zones; rates; emergence numbers; and other items relating to telephone use.
The next section of the telephone directory typically contains the residence listing or entries （条目） of community residents. The third section contains business listing or entries of local businesses and organizations. In some less populated or rural areas, the residence and business listing may be combined in one section.
Some local directories contain listing of local, state and federal government offices and agencies. These listings might be united into the business listing section, or they may be in a separate section of the phone book. These government listings typically are arranged by the name of the state government and then by departments or agencies.
