The original North American area codes were established by the American Telephone and Telegraph Company (AT&T) in 1947, following the demonstration of regional Operator Toll Dialing during the World War II period. The program had the goal of speeding the connecting times for long-distance calling by eliminating intermediary telephone operators. Expanding this technology for national use required a comprehensive and universal, continent-wide telephone numbering plan.

Englewood, New Jersey was incorporated on March 17, 1899. Beginning in 1980, Englewood switched from a Mayor-Council form of government to a modified Council-Manager plan of government in accordance with a Special Charter granted by the New Jersey Legislature. Under this charter, the mayor retains appointive and veto powers, while the council acts as a legislative and policy making body, with some power to appoint and confirm appointments. The City Council consists of five members, each elected for a three-year term. Four are elected from the individual wards in which they live and the other is elected by a citywide vote as an at-large member. The city is divided into four wards which are approximately equal in population. Administrative functions are responsibilities of the City Manager. The six seats in the governing body are elected in a three-year cycle as part of the November general election, with wards two and four both up together, followed a year later by wards one and three, and then the at-large council and mayoral seats. Each ward votes in two of the three years in the cycle, once for its ward seat, in the other year for the two positions voted at-large and one year with no election. The terms begin on January 1 of year after the November election.

Operator Toll Dialing was a telephone call routing and toll-switching system for the Bell System and the independent telephone companies in the United States and Canada that was developed in the 1940s. It automated the switching and billing of long-distance calls. The concept and technology evolved from the General Toll Switching Plan of 1929, and gained technical merits by the cutover of a new type of crossbar switching system in Philadelphia to commercial service in August 1943. This was the first system of its kind for automated forwarding of calls between toll switching centers, but it served customers only for regional toll traffic. It established initial experience with automatic toll switching for the design of a nationwide effort that was sometimes referred to as Nationwide Operator Toll Dialing.
AT&T Communications, Inc., was a division of the AT&T Corporation that, through 23 subsidiaries, provided interexchange carrier and long-distance telephone services.
