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.

“On the whole, yes, I would rather be the Chief Justice of the United States, and a quieter life than that which becomes at the White House is more in keeping with the temperament, but when taken into consideration that I go into history as President, and my children and my children’s children are the better placed on account of that fact, I am inclined to think that to be President well compensates one for all the trials and criticisms he has to bear and undergo.”

—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)
“We can beat all Europe with United States soldiers. Give me a thousand Tennesseans, and I’ll whip any other thousand men on the globe!”
