What is an Area Code?
Definition of an Area Code
An area code is a three-digit number that forms the first part of a telephone number in North America. It identifies the geographic region of the phone number and helps route calls efficiently.
Importance of Area Codes
Area codes are essential for distinguishing between regions, ensuring calls are directed properly, and facilitating local and long-distance communication. For businesses, using the correct area code builds credibility and local presence.
How Area Codes Work in the USA
The United States uses the North American Numbering Plan (NANP), which divides regions into specific area codes. Each area code is associated with a unique geographic location, and Miami is no exception.
