About area code 617
Area code 617 is one of the North American Numbering Plan (NANP) codes serving Massachusetts. In the NANP a full number looks like +1 (617) NXX-XXXX: the +1 is the country code for the US and Canada, 617 is the area code, and the remaining seven digits identify the specific line. A call is charged by your own carrier's plan, not by the area code itself.
