History of the 857 Area Code
The 857 area code was introduced in 2001 as an overlay to the existing 617 area code. This change was implemented to address the growing demand for new telephone numbers in the region, driven by the proliferation of mobile phones and other communication devices. Overlays are a common solution to number exhaustion, allowing for the continued use of existing numbers while providing additional capacity.
