List Of Nanp Area Codes
The North American Numbering Plan (NANP) divides the territories of its members into geographic numbering plan areas (NPAs). Each NPA is identified by one or more numbering plan area codes (''NPA codes'', or ''area codes''), consisting of three digits that are prefixed to each local telephone number having seven digits. A numbering plan area with multiple area codes is called an overlay plan, overlay. Area codes are also assigned for non-geographic purposes. The rules for numbering NPAs do not permit the digits ''0'' and ''1'' in the leading position.AT&T (1955) ''Notes on Distance Dialing'' Area codes with two identical trailing digits are ''easily recognizable codes'' (ERC). NPAs with ''9'' in the second position are reserved for future format expansion. Area codes in numerical order Area codes that are not in use are listed in italic type face; and unassignable codes are bolded. The column ''Date'' lists either the date or year of assignment before implementation, or the in-se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American Numbering Plan
The North American Numbering Plan (NANP) is an integrated telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1, World Numbering Zone 1 and has the telephone country code, country code ''1''. Some North American countries, most notably Telephone numbers in Mexico, Mexico, do not participate in the NANP. The concepts of the NANP were devised originally during the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone companies in North America in Operator Toll Dialing. The first task was to unify the diverse local telephone numbering plans that had been established during the preceding decades, with the goal to speed call completion times and decrease the costs for long-distance calling, by reducing manual labor by switchboard operators. Eventually, it prepared the continent for direct-dialing of long-distance calls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Code 204
Area is the measure of a region's size on a surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). Two different regions may have the same area (as in squaring the circle); by synecdoche, "area" sometimes is used to refer to the region, as in a " polygonal area". The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area ...

Area Code 475
Area codes 203 and 475 are telephone area codes in the North American Numbering Plan (NANP) for the southwestern part of the U.S. state of Connecticut. The numbering plan area (NPA) is mostly coextensive with the Connecticut portion of the New York metropolitan area, and comprises most of Fairfield County, all of New Haven County, and a small portion of Litchfield County. When the American Telephone and Telegraph Company (AT&T) established the first nationwide numbering plan in 1947, Connecticut received only a single area code, 203, of the 86 original North American area codes. On August 28, 1995 the state was divided into two NPAs, reducing the area of 203 to today's extent and adding area code 860 for the region outside. Area code 860 was eventually overlaid with 959, and NPA 203 received a second area code when 475 was added on December 12, 2009. This overlay was first proposed by the Connecticut Department of Public Utility Control in August 1999. Even though area ...
