Ten-digit Dialing
Ten-digit dialing is a telephone dialing procedure in the countries and territories of the North American Numbering Plan (NANP). It is the practice of including the area code of a telephone number when Dialling (telephony), dialing to initiate a telephone call. When necessary, the ten-digit number may be prefixed with the trunk code ''1'', which is referred to as ''1+10-digit dialing'' or ''national format''. History The implementation and expansion of the North American Numbering Plan between 1947 and 1992 preserved a long-standing practice in the United States and Canada that callers should only need to dial the local seven-digit telephone number when placing a call within the caller's exchange area or within the home numbering plan area (NPA). In seven-digit dialing, callers dial the three-digit central office code and the four-digit station number of the destination telephone if it resides in the same numbering plan area. Dialing of an area code before the telephone number, ref ... [...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] |

List Of Telephone Country Codes
Telephone country codes are telephone number prefixes for reaching subscribers in foreign countries or areas by international direct dialing (IDD). Country codes are defined by the International Telecommunication Union (ITU) in ITU-T standards E.123 and E.164 and constitute the international telephone numbering plan of the public switched telephone network (PSTN) and other networks. Overview This table lists in its first column the initial digits of the country code shared by each country in each row, which is arranged in columns for the last digit (x). When three-digit codes share a common leading pair, the shared prefix is marked by an arrow, () pointing down and left to the three-digit codes. Unassigned codes are denoted by a dash (). Countries are identified by ISO 3166-1 alpha-2 country codes; codes for non-geographic services are denoted by two asterisks ().

Area Code 867
Area code 867 is the thelephone area code in the North American Numbering Plan (NANP) for the three Canadian territories, all of which are in Northern Canada. The area code was created on October 21, 1997, for a new numbering plan area (NPA) established from combining regions that were previously served with area code 403 and area code 819.

Area Code 904
Area codes 904 and 324 are telephone area codes in the North American Numbering Plan for most of the First Coast (northeast) region of the U.S. state of Florida. The numbering plan area comprises most of the metropolitan area of Jacksonville. It includes all of Duval County, St. Johns County, Nassau County, and Baker County, and almost all of Clay County. Area code 904 was created in an area code split of area code 305 in 1965. In 2024, the numbering plan received a second area code, 324 , through the creation of an overlay complex to mitigate central office code exhaustion and provide additional telephone numbers in the area. History In 1947, the American Telephone and Telegraph Company (AT&T) designated the entire state of Florida as a single numbering plan area, and assigned area code 305 as a destination routing code for Operator Toll Dialing. The southwest portion was split off in 1953 with area code 813. The northern half of Florida, including Jacksonville, was assign ...

Area Codes US 10D Changing L48
Area is the Measure (mathematics), measure of a Domain (mathematical analysis), region's size on a surface (mathematics), 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 (mathematics), boundary of a solid geometry, 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 plane curve, 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 In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
