History of the 339 Area Code

The 339 area code was introduced on May 2, 2001, as an overlay to the existing 781 area code. This change was implemented to accommodate the growing demand for new telephone numbers in the region. Overlays are a common solution when an area exhausts its available phone numbers, allowing for the continued issuance of new numbers without requiring existing customers to change their numbers. For more details on area code assignments, visit the North American Numbering Plan Administrator (NANPA).
