Area Code Basics

Before delving into the specifics of the 339 area code, it is essential to understand some basic information about area codes in general. An area code is a three-digit number used to identify a specific geographic region within a country or a state.

In the United States, area codes are assigned by the North American Numbering Plan Administration (NANPA), responsible for planning and allocating telephone numbers throughout the country. Typically, each area code is assigned to a specific state or region, and every region can have multiple area codes depending on its population and telephone usage.

The 339 area code was first introduced on May 2, 2001, as an overlay for the 781 area code, which ran out of available phone numbers. This means the two area codes now cover the same geographic region, but new phone numbers are assigned the 339 area code instead of 781. The introduction of the 339 area code was a classic example of NANPA’s strategy of area code overlays, which delay the exhaustion of available phone numbers in a particular area.
