617 Area code history

The American area code 617 is one of the original 86 area codes created by AT&T and the Bell System in 1947. It originally served eastern Massachusetts including Boston. 617 was split in 1997 creating the need to update some of the phone numbers to area code 781. In 2001, area code 857 was created and is currently an overlay to 617. This area code now serves Boston and 12 other cities.
