Area Code 868
The area code 868 is assigned to Trinidad and Tobago, a member of the North American Numbering Plan (NANP). The telephone numbering plan for the country is known as the National Numbering Plan. It is part of a system used for assigning telephone numbers in Trinidad and Tobago, and functions as a part of the North American Numbering Plan (NANP). It is regulated by the Telecommunications Authority of Trinidad and Tobago, which holds responsibility for telecommunications in the country. Due to a long established affiliation with NANP, phone numbers in the Republic of Trinidad and Tobago are often styled as "(868) Telephone exchange, NXX-telephone number, xxxx". However, the ITU-T, International Telecommunications Union's standards such as E.164 and E.123 both strongly advocate the inclusion of a "+1" prefix to indicate "868" is a part of the NANP. History Area code 868 ("TNT") was created during a split from the original Area code 809 with permissive dialing beginning 1 June 1997. ...

North American Numbering Plan
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 Fede ...

Phone Number
A telephone number is a sequence of digits assigned to a landline telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices for data transmission via the public switched telephone network (PSTN) or other public and private networks. A telephone number serves as an address for switching telephone calls using a system of destination code routing. Telephone numbers are entered or dialed by a calling party on the originating telephone set, which transmits the sequence of digits in the process of signaling to a telephone exchange. The exchange completes the call either to another locally connected subscriber or via the PSTN to the called party. Telephone numbers are assigned within the framework of a national or regional telephone numbering plan to subscribers by telephone service operators, which may be commercial entities, state-controlled administrations, or oth ...

Area Code 473
Area code 473 is the local telephone area code of Grenada, Carriacou and Petite Martinique. The 473 area code, which spells GRE, was created during a split from the original 809 area code which began permissive dialing on 31 October 1997 and ended 31 October 1998. For calls placed within Grenada, Carriacou or Petite Martinique, only the seven-digit local number is dialed. Calls to Grenada from anywhere in the United States or Canada are dialed 1 + 473 + seven-digit phone number. Use in telephone fraud The 473 area code has been linked to a form of telephone fraud known as the "one ring scam". The person perpetrating the scam calls the victim via a robodialer or similar means, sometimes at odd hours of the night, then hangs up when the phone is answered with the hope that the victim will be curious enough to call the number back. When the victim does this, an automatic $19.95 international call fee is charged to their account, as well as $9.00/min thereafter. Similar scams have be ...

Area Code 246
Area code 246 is the telephone area code in the North American Numbering Plan (NANP) for Barbados. Telecommunication services in Barbados are regulated by the Government of Barbados's telecommunications unit. The number ''246'' spells ''BIM'' on an alpha-numeric telephone keypad, a nickname for the island. Due to a long established affiliation with the NANP, telephone numbers in Barbados are often styled as ''(246) NXX-xxxx''. International standards, such as E.123, advocate the inclusion of the prefix ''+1'' to indicate ''246'' is a part of the NANP. History Area code 246 was created in a split of area code 809, which was the original area code for most of the Caribbean. Permissive dialing was possible from 1 July 1996 to 15 January 1997 at which time all calls placed to Barbados required the use of the prefix ''1 246'' prefix.

Area Codes In The Caribbean
The integration of the Caribbean telephone networks into the North American Numbering Plan (NANP) began with the assignment of area codes in the Caribbean in 1958, when area code 809 was designated for Bermuda and any other potential participant island countries. From 1958 to 1999, most of the British West Indies in the Caribbean Basin, Bermuda, the U.S. Virgin Islands, the Dominican Republic and Puerto Rico shared area code 809. By the mid-1990s, with the proliferation of fax machines, mobile phones, computers, and pagers in the region, the pool of available central office codes was exhausting. Beginning with Bermuda in November 1994, and The Bahamas, Puerto Rico, and Barbados in 1995, several countries in the Caribbean received individual area code assignments from the NANPA, effectively splitting area code 809. By 1999, it was retained only by the Dominican Republic, following the departure of Saint Vincent and the Grenadines from using the area code. Assignments Sint Maart ...

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 ...

Telephone Numbers In The United Kingdom
Telephone numbers in the United Kingdom are administered by the Office of Communications (Ofcom). For this purpose, Ofcom established a telephone numbering plan, known as the ''National Telephone Numbering Plan'', which is the system for assigning telephone numbers to subscriber stations. The numbers are of variable length. Local numbers are supported from land-lines or numbers can be dialled with a '0'-lead prefix that denotes either a geographical region or another service. Mobile phone numbers have their own prefixes which are not geographical and are completely portable between providers. Structure All mobile numbers, nearly all geographic numbers and nearly all non-geographic numbers have 10 national (significant) numbers after the "0" trunk code. The overall structure of the UK's National Numbering Plan is: A short sample of geographic numbers, set out in the officially approved (Ofcom) number groups: In the United Kingdom, area codes are two, three, four or, excep ...

List Of Country Calling Codes
Country calling codes or country dial-in codes are telephone number prefixes for reaching telephone subscribers in the networks of the member countries or regions of the International Telecommunication Union (ITU). The codes are defined by the ITU-T in standards E.123 and E.164. The prefixes enable international direct dialing (IDD) and are also referred to as ''international subscriber dialing'' (ISD) codes. Country codes are a component of the international telephone numbering plan and are necessary only when dialing a telephone number to establish a call to another country. Country codes are dialed before the national telephone number. By convention, international telephone numbers are represented by prefixing the country code with a plus sign (+), which also indicates to the subscriber that the local international call prefix must first be dialed. For example, the international call prefix in all countries of the North American Numbering Plan is 011, while it is 00 in most ...

Toll-free Telephone Number
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls. For the calling party, a call to a toll-free number from a landline is free of charge. A toll-free number is identified by a dialing prefix similar to an area code. The specific service access varies by country. History The features of toll-free services have evolved as telephone networks have evolved from electro-mechanical call switching to computerized stored program controlled networks. Originally, a call billed to the called party had to be placed through a telephone company operator as a collect call, often long-distance. The operator had to secure acceptance of the charges at the remote number, or even transfer that decision to a long-distance operator, before manually completing the call. Some large businesses and government offices received large numbers of collect calls, which proved time-consuming for operators and the callers. Manual toll-free systems Prior ...

Seven-digit Dialing
Seven-digit dialing is a telephone dialing procedure customary in some territories of the North American Numbering Plan (NANP) for dialing telephone numbers in the same numbering plan area (NPA). NANP telephone numbers consist of ten digits, of which the leading three are the area code. In seven-digit dialing it is not necessary to dial the area code. The procedure is also sometimes known as ''local format'' or ''network format''. History Originally, telephone exchanges consisted of manual switchboards operated by switchboard operators. Telephone numbers had typically two to four digits, depending on the size of the community. As the number of subscribers grew, multiple exchanges served individual neighborhoods of large cities. Multiple exchanges were identified by a central office name and typically four digits, such as "Pennsylvania 5000". A rural telephone number, often party line, had often up to four digits plus a letter or letter and digits to indicate which of the multipl ...
