Telephone Numbers In The United States

The North American Numbering Plan (NANP) is an integrated telephone numbering plan that encompasses 24 countries and territories primarily in North America and the Caribbean.

The NANP is a standardized system of numbering plan areas (NPA) using telephone numbers consisting of three-digit area code, a three-digit central office code, and a four-digit station number. 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. The NANP is administered by the North American Numbering Plan Administration (NANPA), a service operated by Neustar corporation. The international calling code for the NANP is 1. Not all North American countries participate in the NANP.

Famous quotes containing the words united states, states, united, numbers and/or telephone:

    In a moment when criticism shows a singular dearth of direction every man has to be a law unto himself in matters of theatre, writing, and painting. While the American Mercury and the new Ford continue to spread a thin varnish of Ritz over the whole United States there is a certain virtue in being unfashionable.
    John Dos Passos (1896–1970)

    Maybe we were the blind mechanics of disaster, but you don’t pin the guilt on the scientists that easily. You might as well pin it on M motherhood.... Every man who ever worked on this thing told you what would happen. The scientists signed petition after petition, but nobody listened. There was a choice. It was build the bombs and use them, or risk that the United States and the Soviet Union and the rest of us would find some way to go on living.
    John Paxton (1911–1985)

    ... when we shall have our amendment to the Constitution of the United States, everyone will think it was always so, just exactly as many young people believe that all the privileges, all the freedom, all the enjoyments which woman now possesses were always hers. They have no idea of how every single inch of ground that she stands upon to-day has been gained by the hard work of some little handful of women of the past.
    Susan B. Anthony (1820–1906)

    What culture lacks is the taste for anonymous, innumerable germination. Culture is smitten with counting and measuring; it feels out of place and uncomfortable with the innumerable; its efforts tend, on the contrary, to limit the numbers in all domains; it tries to count on its fingers.
    Jean Dubuffet (1901–1985)

    Women who marry early are often overly enamored of the kind of man who looks great in wedding pictures and passes the maid of honor his telephone number.
    Anna Quindlen (b. 1952)
