Area codes are the first three digits of a ten-digit phone number used in the United States and Canada. These codes are used to identify a specific geographic location and are essential for directing calls to the appropriate phone line. In the United States, area codes are assigned by the North American Numbering Plan Administration (NANPA) and can change over time as new codes are added or existing codes are split or overlaid.
