List of New Jersey area codes
The area codes in the U.S. State of New Jersey are a component of the North American Numbering Plan.
Area code 201 was the original, sole area code for New Jersey in 1947, when the American Telephone and Telegraph Company (AT&T) devised the first continental telephone numbering plan. It was also the first area code assigned in the numbering plan.
In 1956, New Jersey was divided into two numbering plan areas, a northern area which retained the code 201, and a southern area which received the assignment of area code 609.[1][2][3] This separated the two population centers (Philadelphia suburbs, and New York City suburbs) into distinct call routing systems for out-of-state long-distance calls. However. until July 1963, New Jersey callers could dial any telephone in the state with seven-digit dialing, without using the area code. In July 1963 central office code protection was lifted and the use of the area code was mandatory when dialing out of the caller's numbering plan area.[4]
