Abstract: The geographic coverage of all telephone companies in the United States is presented in a series of maps depicting the operating areas served by Bell and each of the various independent telephone companies. Tables are also presented of state-by-state listings of (l) almost 1500 telephone companies and their headquarters, and (2) the land areas of each state's major telephone companies. In the future, this updated version of telephone company areas should be more useful than the original 1973 report, since it was plotted with an interactive computer system, which has the capability of updating boundary changes with minimal effort.
Keywords: telephone company areas; independent telephone companies; telephone company maps; interactive computer graphic system
