Area Codes in The United States

Area Codes In The United States

The North American Numbering Plan (NANP) is an integrated telephone numbering plan administered by Neustar (formerly Lockheed Martin IMS) which encompasses 24 countries and territories, including the United States and its territories, Canada, Bermuda, and 17 nations of the Caribbean. The term is also used, by metonymy, to refer to the geographic area in which that plan has been implemented.

The NANP is a standardized system of numbering plan areas (NPA), which have evolved over time into a system of three-digit area codes and seven-digit telephone numbers. Through this plan, telephone calls can be directed to particular regions of the larger NANP public switched telephone network (PSTN), where they are further routed by the local networks.

    To be President of the United States, sir, is to act as advocate for a blind, venomous, and ungrateful client; still, one must make the best of the case, for the purposes of Providence.
    John Updike (b. 1932)

    In the United States there’s a Puritan ethic and a mythology of success. He who is successful is good. In Latin countries, in Catholic countries, a successful person is a sinner.
    Umberto Eco (b. 1932)

    Whether we regard the Women’s Liberation movement as a serious threat, a passing convulsion, or a fashionable idiocy, it is a movement that mounts an attack on practically everything that women value today and introduces the language and sentiments of political confrontation into the area of personal relationships.
    Arianna Stassinopoulos (b. 1950)

    We must trust infinitely to the beneficent necessity which shines through all laws. Human nature expresses itself in them as characteristically as in statues, or songs, or railroads, and an abstract of the codes of nations would be an abstract of the common conscience.
    Ralph Waldo Emerson (1803–1882)

    It is said that the British Empire is very large and respectable, and that the United States are a first-rate power. We do not believe that a tide rises and falls behind every man which can float the British Empire like a chip, if he should ever harbor it in his mind.
    Henry David Thoreau (1817–1862)

    fundamentally an organism has conscious mental states if and only if there is something that it is like to be that organism—something it is like for the organism.
    Thomas Nagel (b. 1938)
