Area Code 330
Area codes 330 and 234 are telephone area codes in the North American Numbering Plan (NANP) for a part of northeast Ohio. The numbering plan area (NPA) includes the cities of Akron, Canton, Youngstown, and Warren. Area code 330 was established on March 9, 1996 in an area code split of area code 216. It was Ohio's first new area code since the creation of NANP in 1947. Area code 234, originally planned as the relief code for the Jacksonville, Florida area, was established on October 30, 2000, to form an overlay plan for the service area. Ten-digit dialing has been mandatory since October 1, 2000.

Area Code
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of the administrative regions of the public switched telephone network (PSTN) and in private telephone networks. For public numbering systems, geographic location typically plays a role in the sequence of numbers assigned to each telephone subscriber. Many numbering plan administrators subdivide their territory of service into geographic regions designated by a prefix, often called an area code or city code, which is a set of digits forming the most-significant part of the dialing sequence to reach a telephone subscriber. Numbering plans may follow a variety of design strategies which have often arisen from the historical evolution of individu ...

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 ...

Area Codes In Ohio
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 squares. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Code 878
Area code 878 is an overlay area code in Southwestern Pennsylvania, centered in Pittsburgh. It simultaneously overlays the region's two existing area codes, 412 and 724, making ten-digit dialing mandatory in the Pittsburgh area. 412 had served southwestern Pennsylvania for 41 years before 724 was created for most of the old 412 territory outside of Pittsburgh in 1998. Bell Atlantic (now part of Verizon), the main telephone provider in the area, wanted to implement 724 as an overlay to spare residents and businesses the burden of changing their numbers. However, overlays were still a new concept at the time, and met with considerable resistance due to the need for ten-digit dialing. Thus, the proposal was changed to a geographic split. Within two years, however, both 412 and 724 were on the verge of exhaustion. Overlays had gained more acceptance by then, so 878 was implemented as an overlay. It came into effect on August 17, 2001.

Area Code 724
Area code 724 is a Commonwealth of Pennsylvania telephone area code in western and southwestern Pennsylvania, including most of the suburbs of Pittsburgh. It was split from area code 412 on February 1, 1998. Originally, Bell Atlantic wanted to implement 724 as an overlay of 412. However, overlays were still a new concept at the time, and met with some resistance due to the requirement for ten-digit dialing. For this reason, 724 was implemented as a split, with nearly all of the old 412 territory outside Allegheny County getting the new area code, making it one of the six pairs of "doughnut area codes" in the numbering plan. Within only two years, both 724 and 412 were on the verge of exhaustion due to the Pittsburgh area's rapid growth and the proliferation of cell phones and pagers. By this time, overlays had gained more acceptance, and area code 878 was implemented as an overlay for both the 412 and 724 territories on August 17, 2001. Since that date, ten-digit dialing ...

Area Code 412
Area code 412 is a telephone area code in the North American Numbering Plan (NANP) for the Commonwealth of Pennsylvania. The numbering plan area (NPA) comprises the city of Pittsburgh, most of surrounding Allegheny County, and small portions of Washington and Westmoreland counties. The area code was one of the original North American area codes created in 1947, when it was assigned to the entire southwestern corner of the state. History When the American Telephone and Telegraph Company (AT&T) created the first nationwide telephone numbering plan for the continental United States and Canada in 1947, Pennsylvania was divided into four numbering plan areas. Area code 412 was assigned to the southwestern part of the state, from Butler County to the West Virginia border. On February 1, 1998, nearly all of the old 412 territory outside of Allegheny County was split off and received area code 724, surrounding 412.

Area Codes 419 And 567
Area codes 419 and 567 are telephone area codes in the North American Numbering Plan (NANP) for the northwestern part of the U.S. state of Ohio. The largest city served by these area codes is Toledo (and its suburbs of Holland, Maumee, Northwood, Oregon, Ottawa Hills, Perrysburg, Rossford, Sylvania, Swanton, Waterville, and Whitehouse). History The first nationwide telephone numbering plan of 1947 divided Ohio into four numbering plan areas (NPAs), roughly forming a quadrant layout for telecommunication services in the state. Area code 419 was assigned to the northwest quadrant in the state. The overlay area code 567 was created on January 1, 2002. Despite the presence of Toledo, the state's fourth-largest city, 419 was the last of Ohio's original four numbering plan areas to be split or overlaid. However, because of the choice of an overlay, it is the only one of Ohio's original four NPAs, and one of the few original NPAs not covering an entire state, that still ha ...

Area Codes 304 And 681
Area codes 304 and 681 are telephone area codes in the North American Numbering Plan (NANP) for the entirety of the U.S. state of West Virginia. The numbering plan area was established in October 1947 with area code 304, as one of the eighty-six original North American area codes. Area code 681 was added to the same area in an overlay plan that took effect on March 28, 2009. History Due to West Virginia's low population, the state was one of the last remaining states with only one area code in the early 21st century. With the growth of telecommunication services, in particular proliferation of cell and mobile phones and fax machines, news reports in 2007 indicated that West Virginia would soon need a new area code. On January 29, 2008, the West Virginia Public Service Commission voted 2-1 for a split of numbering plan area 304, while commission chairman Michael Albert dissented in favor of an overlay. The proposed split had Charleston and points south ( Huntington, Bluefi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Codes 740 And 220
Area codes 740 and 220 are telephone area codes in the North American Numbering Plan (NANP) for the southeastern and central parts of Ohio. The numbering plan area (NPA) includes the cities of Athens, Belpre, Cadiz, Chillicothe, Circleville, Coshocton, Delaware, Gallipolis, Heath, Ironton, Jackson, Lancaster, Laurelville, Logan, Marietta, Marion, Mount Vernon, Nelsonville, Newark, Newcomerstown, Pataskala, Portsmouth, Rockbridge, Steubenville, Washington Court House, and Zanesville, Shadyside and the surrounding areas. It does not include the city of Columbus and rate centers in Franklin County which primarily use area code 614. Although it is Ohio's largest area code by geographic size, Southeastern Ohio is largely rural and has fewer residents overall than the rest of the state except in the areas near Columbus. 220 is the lowest-numbered area code in the system, that doesn't have a 0 or 1 in the middle.

Area Code 440
Area code 440 is a North American telephone area code for the state of Ohio, serving parts of the Greater Cleveland area, but not the city of Cleveland or most of its inner suburbs. This area code was established August 16, 1997. Area code 440 was formed by a three-way split of Area code 216, one of the original North American Numbering Plan codes. Area code 330 was created in 1996 from the southern part of 216 and 440 was added the following year to keep up with the increasing number of cellular phones, as well as population factors. Coverage Area code 440 serves most of the southern, western, and eastern suburbs of Cleveland, including the larger cities and communities of Ashtabula, Eastlake, Elyria, Lorain, Mentor, North Olmsted, North Ridgeville, North Royalton, Parma, Solon, Strongsville, Westlake and Willoughby. 440 covers all of Lake and Geauga counties. It serves almost all of Ashtabula and Lorain counties, part of Erie County, the northeast corner of Huron Coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Ohio Area Codes
This is a list of area codes in the state of Ohio with establishment dates. Background When the first area code plan was introduced in 1947, the state was given area codes 216, 419, 513, and 614. In 1996, 330 and 937 were added as splits. In 1997, 440 and 740 were added as splits. In 2000, 234, and in 2002, 567 were added as overlays. In 2015, area code 740 was overlaid with 220, relieving its rapid depletion. In 2016, area code 614 was overlaid with 380 in the Columbus/Central Ohio area for the same reason. In 2020, 326 was added as an all services overlay for 937. Area code 283 will be used as an overlay when 513 in Cincinnati/Southwest Ohio reaches its depletion.
