Telephone area codes for the USA (America)

The area code system of the United States of America is special. Its title “North American Numbering Plan” says it all, because the number system applies to 20 North American countries, including Canada and the USA. The system is administered depending on the area. In the United States, jurisdiction rests with the North American Numbering Plan Administration (NANPA) (to the official website). The so-called Area Code consists of three digits. Each area code is assigned only once within the NANP. The allocation is based simply on the need for a new area code. An example: In the state of Ontario in Canada the area code "807" is used. In the US state of Hawaii, the area code "808" applies. The responsible authorities can also reserve area codes for their area of ​​responsibility.
Another special feature of the NANP is that there is no distinction between landline numbers and mobile phone numbers. Each participant has a 10-digit number, ie a personal 7-digit "location-dependent" participant number that follows the 3-digit area code.
