Area Code 670
Area code 670 is the telephone area code in the North American Numbering Plan (NANP) for the U.S. Commonwealth of the Northern Mariana Islands (CNMI). It was created with a permissive dialing period from July 1, 1997 to July 1, 1998, when it permanently replaced the previous International Telecommunication Union (ITU) country code 670. Country code 670 was later assigned to East Timor. History Although the Northern Mariana Islands (NMI) became a commonwealth in 1978 and the United States assumed sovereignty in 1986, calling from the United States to CNMI remained an international call (011-670-xxx-xxxx). After the CNMI was added to the North American Numbering Plan, the U.S. Federal Communications Commission (FCC) regulated calls between the U.S. and CNMI as "domestic", causing a reduction in the cost of telephone calls and making NANP toll-free access available to callers from the CNMI, which became popular with the advent of pre-paid phone cards. However, since no mobile teleph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
Commonwealth Of The Northern Mariana Islands
The Northern Mariana Islands, officially the Commonwealth of the Northern Mariana Islands (CNMI), is an unincorporated territory and commonwealth of the United States consisting of 14 islands in the northwestern Pacific Ocean.Lin, Tom C.W.Americans, Almost and Forgotten 107 California Law Review (2019) The CNMI includes the 14 northernmost islands in the Mariana Archipelago; the southernmost island, Guam, is a separate U.S. territory. The Northern Mariana Islands were listed by the United Nations as a non-self-governing territory until 1990. During the colonial period, the Northern Marianas were variously under the control of the Spanish, German, and Japanese empires. After World War II, the islands were part of the United Nations trust territories under American administration before formally joining the United States as a territory in 1986, with their population gaining United States citizenship.

Permissive Dialing
In North America, permissive dialing is the ability to make phone calls in an area subject to a newly introduced area code by using both the new and preexisting dialing methods. When an area is given a new area code under a split plan, the area's previous area code would no longer be valid for calls in the area, so calls to numbers using the old area code will not work. To alleviate misdialing frustration, the local routing can be set up such that both the old and new area codes will work for the same telephone exchange. During this period, the local numbering authority must not reassign the area's existing exchanges to the remaining area of the old area code, nor vice versa. At the end of the permissive dialing period, the old area code is no longer valid for numbers in the affected area. Under an overlay plan, permissive dialing refers to the ability to continue to connect calls via 7-digit dialing while also making 10-digit dialing valid. Again, the affected area must not int ...

It was established on 17 May 1865 as the International Telegraph Union, the first formal and permanent international organization. The organization significantly predates the UN, making it the oldest UN agency. Doreen Bogdan-Martin is the Secretary-General of ITU, the first woman to serve as its head. The ITU was initially aimed at helping connect Telegraphy, telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
+670
Until September 1999, East Timor (now Timor-Leste) formed part of the Indonesian numbering plan, using the country code 62, followed by area codes for the two largest cities, Dili (390) and Baucau (399). Following the violence in the wake of Indonesia's departure from the territory, most of the telecommunications infrastructure was destroyed, and Telkom Indonesia withdrew its services from East Timor. In the interim, the code 672, used by the Australian External Territories, was used to reach numbers in the territory. Originally, the 672 code had been allocated to the then Portuguese Timor, before its invasion and occupation in 1975. A new country code, 670, was allocated to East Timor, but international access often remained severely limited. A complicating factor is that 670 was previously used by the Northern Marianas, with many carriers not aware that the code is now used by Timor-Leste, and that the Northern Marianas, now part of the North American Numbering Plan, use the ...

East Timor
Timor-Leste, also known as East Timor, officially the Democratic Republic of Timor-Leste, is a country in Southeast Asia. It comprises the eastern half of the island of Timor, the coastal exclave of Oecusse in the island's northwest, and the outer islands of Atauro and Jaco. Timor-Leste shares a land border with Indonesia to the west, and Australia is the country's southern neighbour, across the Timor Sea. The country's size is . Dili, on the north coast of Timor, is its capital and largest city. Timor was settled over time by various Papuan and Austronesian peoples, which created a diverse mix of cultures and languages linked to both Southeast Asia and Melanesia. East Timor came under Portuguese influence in the sixteenth century, remaining a Portuguese colony until 1975. Internal conflict preceded a unilateral declaration of independence and an Indonesian invasion and annexation. The subsequent Indonesian occupation was characterised by extreme abuses of human ...

Area Code 671
The area code 671 is the local telephone area code of the United States territory of Guam. It was created with the beginning of permissive dialing on July 1, 1997, replacing Guam's previous International Telecommunication Union country code 671 at the end of permissive dialing on July 1, 1998. Origins Prior to 1997, callers from the rest of the United States had to dial '011-671' and then the seven-digit telephone number to reach Guam, similar to international calls. As international calling rates began to fall in the more competitive destination countries during the 1990s, it became a considerable financial burden for people on the United States mainland to place calls to the United States territory of Guam, especially for those who were stationed in United States military bases there. Calling costs After Guam was added to the North American Numbering Plan, the Federal Communications Commission (FCC) regulated calls to and from Guam as "domestic", hence dramatically lowering the ...

Area Code 808
Area code 808 is a telephone area code in the North American Numbering Plan (NANP) for the Hawaiian Islands, comprising the windward and the leeward islands. The area code also serves Wake Island in the western Pacific Ocean. The code was assigned on August 8, 1957, about two years before the statehood of Hawaii. Slightly over 1.4 million people live in Hawaii. Despite the state's rapid growth, and the proliferation of mobile numbers (particularly in Oahu, which includes Honolulu), a single area code is projected to be enough to serve the state until at least the third quarter of 2035. Prior to October 2021, area code 808 had telephone numbers assigned for the central office code 988. In 2020, ''988'' was designated as a nationwide three-digit dialing code for the National Suicide Prevention Lifeline. This created a conflict for Hawaii's exchanges, all of which permitted seven-digit dialing. Therefore, area code 808 transitioned to ten-digit dialing on October 24, 2021. Marcus M ...
