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. Numbering plan areas may be assigned multiple area codes to provide adequate numbering resources, in which case the local numbering plan is called an overlay. Area codes are also assigned for non-geographic purposes. The rules for numbering NPAs do not permit the digits ''0'' and ''1'' as the leading digit, which also applies for central office codes.AT&T (1955) ''Notes on Distance Dialing'' NPAs with ''9'' as the second digit are reserved for future format expansion. Area codes with two identical trailing digits are considered easily recognizable codes (ERC), which are reserved, or used for systemwide services. Area codes in numerical order 200–299 300–399 ...

NANP Countries
The North American Numbering Plan (NANP) is a 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 and has the international calling code ''1''. Some North American countries, most notably Mexico, do not participate in the NANP. The NANP was originally devised in the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone operators in North America. The goal was to unify the diverse local numbering plans that had been established in the preceding decades and prepare the continent for direct-dialing of calls by customers without the involvement of telephone operators. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administrator (NANPA), a service that has been procured from the private sector by the Feder ...

Area Code 860
Area is the quantity that expresses the extent of a region on the plane or on a curved 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). 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 of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such sq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Code 206
Area code 206 is a North American telephone area code in the U.S. state of Washington serving Seattle and most of its innermost suburbs. The numbering plan area (NPA) includes such suburbs as Shoreline, Lake Forest Park, the islands of Mercer, Bainbridge, and Vashon, and portions of metropolitan Seattle from Des Moines to Woodway. As of January 2017, 206 was one of the last urbanized numbering plan areas in the North American Numbering Plan without an overlay area code, making Seattle one of the largest cities where calls could still be originated by seven-digit dialing. On January 28, 2017, area code 564 was activated as an overlay for most of the western portion of Washington, and ten-digit dialing became mandatory on July 29, 2017.
