How are phone numbers allocated in the U.S. and the rest of North America ?


To facilitate the organization and use of phone numbers, different area codes are allocated to different regions of the United States. The same system may apply for other countries too, such as Canada. These area codes work in a similar way than the international dialing codes of each country.
Some American states which have a low population, such as Montana, have a single area code, while other states, such as Texas and New York, have more than one area code. The allocation of area codes in the United States, Canada and the Caribbean is done by the NANPA (The North American Numbering Plan Administration).
When dialing a number in the U.S, the first three digits belong to the area code. As it was said before, these codes depend on the state and city where the phone is registered. There are some area codes that serve specific purposes. For example the 800 area code is generally known as the free number code, because it is reserved for phone numbers in which the recipient of the call pays for it instead of the caller. Because there is a limited amount of areas covered by the phone service, not every possible number combination represents an area code, which means that some numbers don’t represent anything and if you dial them you will be informed by an automatic operator that the number or area code is currently non existent.
The next three digits belong to the exchange or prefix and they are reserved for different telephone companies and it is represented by the letters NXX. All telephone companies have at least one NXX that belongs uniquely to them and some companies may have more than one NXX. Some combination of numbers are not in use, the same as with area codes.
The final four digits of any phone number are called the local number or the subscriber and  they are given by your telephone company. Counting all the area codes, the prefixes and subscriber available, it is estimated that the NANPA is able to provide more than a billion and a half phone numbers, which represents four phone numbers per person in the United States and Canada. This sum may actually not be enough in the future, since nowadays one single person may actually use more than four different phone numbers: A landline phone at work and another at home, a fax machine and a couple of cellphone numbers. However, the NANPA is currently able to create more area codes and prefixes to supply the market.

History of the American area code system


The American area code system was originally developed in the forties by AT&T and the Bell System. NPA (number plan areas) were created in order to organize the coverage of the phone service. Nowadays the NPA are simply called “area codes”. This area code system was followed by the international dialing code system in the fifties, which made it possible for people to make international calls without the need of an operator. The International Telecommunications Union (ITU) assigned the international calling code 1 to the NANPA. This is therefore the number used for incoming calls to the United States, Canada and the Caribbean countries comprised by the  NANPA.
Currently the NANPA counts with 395 area codes, 317 of which belong to American areas. The rest of the area codes belong to coverage areas in Canada and the Caribbean, though there are 17 area codes which are non-geographic, for instance the 800-free numbers.
