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.

“Nova Scotia, New Brunswick, and Canada are the horns, the head, the neck, the shins, and the hoof of the ox, and the United States are the ribs, the sirloin, the kidneys, and the rest of the body.”
—William Cobbett (1762–1835)
“Men will not give up their privilege of helplessness without a struggle. The average man has a carefully cultivated ignorance about household matters—from what to do with the crumbs to the grocer’s telephone number—a sort of cheerful inefficiency which protects him better than the reputation for having a violent temper.”
—Crystal Eastman (1881–1928)
“... there are persons who seem to have overcome obstacles and by character and perseverance to have risen to the top. But we have no record of the numbers of able persons who fall by the wayside, persons who, with enough encouragement and opportunity, might make great contributions.”
—Mary Barnett Gilson (1877–?)
“... the yearly expenses of the existing religious system ... exceed in these United States twenty millions of dollars. Twenty millions! For teaching what? Things unseen and causes unknown!... Twenty millions would more than suffice to make us wise; and alas! do they not more than suffice to make us foolish?”
—Frances Wright (1795–1852)
“When some one remarked that, with the addition of a chaplain, it would have been a perfect Cromwellian troop, he observed that he would have been glad to add a chaplain to the list, if he could have found one who could fill that office worthily. It is easy enough to find one for the United States Army. I believe that he had prayers in his camp morning and evening, nevertheless.”
—Henry David Thoreau (1817–1862)
