History of 339 Area Code
The 339 area code was introduced in 2001 as an overlay for the 781 area code in eastern Massachusetts. The 781 area code itself was created in 1997 as a split from 617 to relieve number exhaustion in the Greater Boston region.
In 2001, the 339 overlay was added over the same geographic area as 781, covering Boston’s suburban communities such as Waltham, Lynn, Medford, Revere, and surrounding towns. This change also introduced mandatory 10-digit dialing for local calls within the region.

339 Area Code: Dialing Format, Prefixes & Network Coverage
The 339 area code serves eastern Massachusetts as an overlay to the 781 area code under the North American Numbering Plan, and requires 10-digit dialing for all local calls. For example, a local number is dialed as 339-XXX-XXXX, while domestic long-distance calls use a leading “1” before the full number, and international callers dial their exit code followed by 1 and the complete phone number.
The area is served by telecommunications providers such as Verizon, AT&T, and T-Mobile under the North American Numbering Plan. Phone numbers are organized into prefix blocks (NXX codes), such as 201, 203, and 222, which are assigned to different carriers to manage call routing and network allocation across the system.
Beyond traditional phone numbers, the 339 area code also works with virtual and VoIP phone systems. Platforms like Calilio enable companies to establish a local presence in Massachusetts remotely without needing multiple physical offices in the region, while offering advanced features such as IVR and AI call analytics.
