How New Jersey Area Codes Work
Area codes are assigned based on geographic regions, and they help ensure that phone numbers are unique and identifiable. In New Jersey, the North American Numbering Plan (NANP) is responsible for managing area codes and phone numbers. The NANP divides the United States into regions, and each region is assigned a three-digit area code. The next three digits represent the central office or exchange, while the last four digits represent the individual phone number.
