History of the 617 Area Code
The 617 area code was one of the original area codes established in 1947. Over the years, it has undergone several changes due to the increasing demand for telephone numbers. In 1988, area code 508 was created as a split from 617 to accommodate the growing population and the proliferation of new technologies. Later, in 1997, area code 781 was introduced, further reducing the geographic area covered by 617. In 2001, area code 857 was overlaid on 617 to provide additional numbering options without requiring existing numbers to change. For more details on area code changes, visit the North American Numbering Plan Administrator (NANPA).
