    Early during the 20th century, the American and Canadian telephone industry had established criteria and circuits for sending telephone calls across the vast number of local telephone networks on the continent to permit users to call others in many remote places in both countries. By 1930, this resulted in the establishment of the General Toll Swit...

    Building a nationwide network in which any telephone could be dialed directly required a systematic numbering system that was easy to understand and communicate. Local telephone numbers varied greatly across the country, from two or three digits in small communities, to seven in the large cities. By the time the Bell Laboratory engineers began effo...

    Most automatic dial switching systems were designed since the early 1920s to provide service for as many as ten-thousand subscriber lines. Each of these switching systems constituted a local telephone exchange, formally known as a central office. Therefore, each telephone connected to a central office had a unique four-digit line or station number....

    By 1945, initial concepts for a nationwide numbering plan anticipated a division of the continent into between fifty and seventy-five numbering plan areas. For this size of the network, a unique two-digit code for each numbering plan area (NPA) would have been sufficient. However, AT&T wanted to preserve existing dialing practices by only dialing t...

    The number of central offices that could be effectively installed with a numbering plan with two letters and one digit for the central office code was expected to be approximately five-hundred, because acceptable names for central offices had to be selected carefully to avoid miscommunication. States or provinces that required this many offices had...

    For several years, area codes could be used only for Operator Toll Dialing by long-distance operators on routes between toll offices equipped with trunk code translation equipment. This absent, operators still had to rely on route operators and office-specific trunk codes, or employ the previous method of ringdown forwarding between intermediate op...
