The 201 area code was one of the original area codes assigned in 1947, and was also the first area code to be assigned in the United States, as part of the North American Numbering Plan. It originally covered the entire state. This was very unusual, since New Jersey is one of the most densely populated states in the nation; it is split almost down the middle between two very large metropolitan areas—the suburbs of New York City to the north and the suburbs of Philadelphia to the south. The North American Numbering Plan Administration took this into account when it assigned 201 to New Jersey. It wanted the number of "clicks" to a minimum for densely populated areas, given the rotary dialing technology in use at the time. New Jersey was thus assigned an area code with 13 clicks, the fastest that could be dialed for a single-state area code under NANPA's original guidelines (0 and 1 were not allowed as the first digit, the second digit was either 0 or 1, and the third digit could not be the same as the second digit).
The area code system entered service in 1951. That year, the first direct-dialed long distance call was made from Englewood, New Jersey to Alameda, California.
In 1958, 201 was restricted to northern New Jersey, with southern New Jersey—including the state capital, Trenton—becoming area code 609.
