supports: The North American Numbering Plan (NANP) is a telephone numbering plan that encompasses 25 distinct regions in twenty countries primarily in North America, including the Caribbean and the U.S. territories. Not all North American countries participate in the NANP. The Caribbean (or ) is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. A telephone number is a sequence of digits assigned to a fixed-line 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 private networks. Most telephone numbers are assigned to one telephone line or one mobile telephone, and most lines or mobiles have one number. 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 administrative regions of the public switched telephone network (PSTN) and they are also present in private telephone networks. A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals suitable for transmission via cables or other transmission media over long distances, and replays such signals simultaneously in audible form to its user. Area code 700 of the North American Numbering Plan is reserved for carrier - specific number assignments to special services or destinations . It was introduced in 1983 in anticipation of the introduction of long distance competition in the US . The area code was intended for presubscribing telephone numbers to particular interexchange carriers . Numbers in this area code are exclusive to the specific carrier , so the destination of a given number in 700 may be different for each carrier . Almost all of the early ' 700 - offerings have faded into history , due to a combination of confusion , blocking of calls to them by many businesses worried about high - charge phone calls , and many alternative services . The number 700 - 555 - 4141 is provided by all carriers who implement the area code . It plays a recording identifying the carrier handling long distance and international calls . While this does not work with most cellular and VOIP systems this identification may help traditional land line consumers who have been slammed into a new carrier . The intent was that interexchange carriers could use 700 numbers to implement new services quickly . When a 700 number is dialed , the local exchange carrier processing the call routes it to the presubscribed interexchange carrier , unless the caller has overridden presubscription by dialing 101XXXX before the number . Thus each interexchange carrier has access to all 7.92 million 700 numbers . 700 numbers are different from all other North American Numbering Plan numbers because the destinations are not unique , and , in fact , depend on the network the caller has selected . In 1992 AT&T introduced a 700 number service branded as AT&T EasyReach 700 . It allowed subscribers to forward calls to their 700 number to any domestic phone number . It allowed either the caller or the subscriber to pay for the incoming calls . If the caller was calling from a phone not pre-subscribed to AT&T as its IXC , the caller was required to dial 10 - ATT prior to dialing the 700 number . This service has since been discontinued . Some carriers have made use of the carrier - specific nature of area code 700 to offer telephony - based services to their subscribers , dialable via ordinary telephones . For example , Vonage has provided weather information with ( 700 ) WEATHER ( 700 - 932 - 8437 ) .
