A telephone prefix is the first set of digits after the country, and area codes of a telephone number. In the North American Numbering Plan countries (country code 1), it is the first three digits of a seven-digit local phone number, the second three digits of the 3-3-4 scheme. In other countries, both the prefix and the number may have ...
Toll-free telephone numbers in the North American Numbering Plan have the area code prefix 800, 833, 844, 855, 866, 877, or 888. Additionally, area codes 822, 880 through 887, and 889 are reserved for toll-free use in the future. 811 is excluded because it is a special dialing code in the group NXX for various other purposes.
This rounded the total number of digits in a subscriber telephone number to ten: a three-digit area code, a three-digit central office code, and four digits for each line. This fixed format defined the North American Numbering Plan as a closed numbering plan , [ 27 ] as opposed to developments in other countries where the number of digits was ...
Mobile phones require full 10-digit number which starts with 3-digit non-geographical area codes 900–990. For international calls abroad or international roaming calls to Russia, E.123 international notation with an international call prefix '+' is the only allowed calling number format. For local calls both 8 and 7 are accepted as a trunk code.
This means that until everyone has adjusted to the new dialing system, users would still be able to dial the shorter, 10-digit numbers. Since currently the 4th digit (or digit 'D') cannot be 1 or 0, if the telephone system detects 1 or 0 in the 4th position it will process the number as a new 12-digit number, and if it is any digit other than 1 ...
Hence the CGIs 001-02-3-4 and 001-002-3-4 would be two completely unrelated cells, which would be in the same country, but belong to two completely distinct operators (02 and 002). From PLMN assignments, it is apparent that such dualities of two-digit and three-digit MNCs with the same number value are avoided.
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.
