What is Area Code 617?

Area code 617 is a North American telephone area code assigned to Boston and its inner metro communities, including Cambridge and Brookline. It was one of the original NANP codes introduced in 1947, making it among the oldest area codes in the country. The code is local rather than toll-free, and it operates on Eastern Time.

For decades, 617 covered all of eastern Massachusetts before splits and overlays carved out new codes for the wider metro. Today, 617 is the recognizable Boston identifier, used by long-established institutions across finance, healthcare, and higher education. The code remains tightly bound to Boston's civic identity, the kind of number locals recognize instantly.

Business Insight

Why do legitimate businesses still get flagged as spam?

Even with a recognizable area code like 617, unknown local numbers still trigger call screening on iPhone and Android. Buyers see "Spam Likely" or no caller ID, and they let the call ring out. The result is missed appointments, lost leads, and slower deals.
