What Is a Phone Number?
A phone number is a unique sequence of digits used to identify and connect telecommunication devices within a network. In the USA, the standard format follows the North American Numbering Plan (NANP): NPA-NXX-XXXX. This system assigns numbers based on area codes (NPA) and local exchanges (NXX), ensuring organized and efficient communication.
code ->+1 (US country code) -> area code -> 7-digit local phone number
When calling internationally, a phone number in the USA includes the +1 country code, which identifies the number as part of the NANP. The +1 is shared by the United States, Canada, and several Caribbean nations, standardizing international connectivity for these regions. The complete international format appears as +1-NPA-NXX-XXXX, where +1 directs the call to a NANP country and the remaining digits specify the regional and subscriber details.
