What is an Area Code?
An area code is a three-digit numerical prefix assigned to a geographic region within a country. In the United States, each area code covers a specific geographical area, such as a state, city, or a portion thereof. The purpose of area codes is to facilitate the routing of telephone calls to the correct destination.
The Evolution of Area Codes in the USA
The North American Numbering Plan (NANP) was introduced in 1947, establishing the framework for area codes. Initially, only 86 area codes were assigned. However, as the population and number of telephone lines grew exponentially, the demand for additional area codes surged. To accommodate this growth, overlay plans were implemented, allowing multiple area codes to serve the same geographic region.
How Area Code for USA International Calls Work
When making an international call to the United States, you’ll typically need to dial the following components:
- Exit code: This is the code used to signal the phone network that you’re making an international call. It varies depending on your country.
- Country code: For the United States, the country code is 1.
- Area code: The three-digit code representing the specific region in the US.
- Local number: The seven-digit phone number within the area code.
For example, to call a number in New York City with the area code 212, you would dial the exit code for your country, followed by 1, 212, and then the seven-digit local number.
