The largest telephone numbering plan in North American is the North American Numbering Plan (NANP), serving 25 regions or countries. Other countries maintain an autonomous numbering plan with distinct country codes within the international E.164 specifications by the International Telecommunication Union.
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. [1] Area codes with two identical trailing digits are easily recognizable codes (ERC). NPAs with 9 in the second position are reserved for future format expansion.
For international access the NANP is assigned the country code 1, which is dialed as a prefix in the international E.164 telephone numbering plan.. The trunk prefix for dialing long-distance calls, across numbering plan area (NPA) boundaries within Canada or to other NANP countries, is also 1.
The prefixes in the Americas start with one of 1,2,5. All countries in the Americas use codes that start with "5", with the exception of the countries of the North American Numbering Plan, such as Canada and the United States, which use country code 1, and Greenland and Aruba with country codes starting with the digit "2", which mostly is used by countries in Africa.
