Glossary Area Code
Area Code
Phone area codes are used in the North American telephone system. An area code is a three-digit code that identifies different calling areas in the United States, Canada, and the Caribbean.
Area codes enable callers to dial out of their local calling areas. Area codes are laid out according to the North American Number Plan (NANP), which is a telephone numbering plan. AnswerConnect is a nationwide company that provides service to all areas served by the NANP.
