Area Codes 970 And 748
Area code 970 is a telephone area code in the North American Numbering Plan (NANP) for the western and northern parts of the U.S. of State of Colorado. The numbering plan area includes Aspen, Breckenridge, Durango, Estes Park, Fort Collins, Glenwood Springs, Grand Junction, Greeley, Loveland, Silverthorne, Steamboat Springs, and Vail. History Area code 970 was established on April 2, 1995 in an area code split of area code 303, which was retained by the Denver metropolitan area. In 2023, the North American Numbering Plan Administrator estimated that area code 970 would reach numbering exhaustion by 2026. On December 18, 2023, the Colorado Public Utilities Commission approved the addition of area code 748 for the all-services distributed overlay of NPA 970. The overlay complex is scheduled for service on July 7, 2025. No central office codes of area code 748 may be installed before complete exhaustion of area code 970.

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 world-wide, as well as within each of the administrative regions of the public switched telephone network (PSTN), and in private telephone networks. In 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. Within such regions designated by area codes, locally unique telephone number are assigned based on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Code 303
__NOTOC__ Year 303 ( CCCIII) was a common year starting on Friday of the Julian calendar. It was known in the Roman Empire as the Year of the Consulship of Diocletian and Maximian (or, less frequently, year 1056 ''Ab urbe condita''). The denomination 303 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Great Persecution: Emperor Diocletian launches the last and largest major persecution of Christians in the Empire. Caesar Galerius and Hierocles are said to have been the instigators. In a series of four edicts published from February 23, 303, to 304, the Christians are forbidden to worship in groups, are made to perform sacrifices, and must surrender sacred texts. Churches are destroyed, and the clergy are arrested en masse. The persecution lasts in some parts of the empire until 313, and thousands of Christians are killed. Those put to ...

List Of North American Numbering Plan 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 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, rea ...s''), 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. 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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Colorado Area Codes
The U.S. state of Colorado is divided into three numbering plan areas in the North American Numbering Plan, with a total of six area codes. Area code 748 is scheduled to be added to numbering plan area 970 in 2025. History Area code 303 is one of the original North American area codes of 1947, and originally served the entire state of Colorado. It remained the state's sole area code for 40 years. Colorado's growth in the second half of the 20th century, particularly in the Denver/Boulder area, created a shortage of numbering resources, so that relief planning was initiated in 1987. On March 5, 1988, southeastern Colorado, including Colorado Springs and Pueblo, was split from 303 and received area code 719. This was intended as a long-term solution, but within five years further demand for numbers and the proliferation of cell phones and pagers (especially in and around Denver) forced another split. The northeastern and western portions of area code 303, including Fort Colli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Colorado
The geography of the U.S. State of Colorado is diverse, encompassing rugged mountainous terrain, vast plains, desert lands, desert canyons, and mesas. Colorado is a landlocked U.S. state. In 1861, the United States Congress defined the boundaries of the new Territory of Colorado exclusively by lines of latitude and longitude, stretching from 37°N to 41°N latitude, and from 102°02'48"W to 109°02'48"W longitude ( 25°W to 32°W from the Washington Meridian). Starting in 1868, official surveys demarcated the boundaries, deviating from the parallels and meridians in several places. Later surveys attempted to correct some of these mistakes but in 1925 the U.S. Supreme Court affirmed that the earlier demarcation was the official boundary. The borders of Colorado are now officially defined by 697 boundary markers connected by straight boundary lines. Colorado, Wyoming, and Utah are the only states that have their borders defined solely by straight boundary lines with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overlay Complex
In telecommunications, an area code overlay complex is a telephone numbering plan that assigns multiple area codes to the same geographic numbering plan area (NPA). Area code overlays are implemented in territories of the North American Numbering Plan (NANP) to mitigate exhaustion of central office codes in growth areas. The method has been in use since 1992, and has been the exclusive method of area code relief since 2007. History From the inception of the North American Numbering Plan in 1947 until 1992, the only method of introducing new area codes was the area code split. It divided an existing numbering plan area (NPA) into multiple regions, one of which retained the existing area code. The other parts were each assigned a new NPA code. The retaining area was usually the historically more established or developed place, and required no numbering changes. It gained numbering capacity by acquiring the central office codes of the other areas, because those were delegated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates communications by radio, television, wire, internet, wi-fi, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was established pursuant to the Communications Act of 1934 to replace the radio regulation functions of the previous Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries in North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Suicide Prevention Lifeline
The Suicide and Crisis Lifeline in the United States, or Suicide Crisis Helpline in Canada, and formerly known as the National Suicide Prevention Lifeline, is a suicide prevention and crisis help line to a network of a large number of crisis centers in the United States and Canada that provide 24/7 service via a toll-free hotline and with the three-digit short code telephone number 9-8-8. In the United States, the 988 short code was implemented in July 2022 as an addition to its predecessor, a 1-800 number that existed since 2005. Call to the hotline are routed to the nearest crisis center that provides immediate counseling and a referral to a local mental health service. The service supports people who call for their own crisis or for someone they care about. A similar operation in Canada was launched on November 30, 2023. United States The 988 Suicide & Crisis Lifeline is a component of the National Suicide Prevention Initiative (NSPI), a multi-project effort to reduce s ...

NANPA
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] |
