Area codes 781 and 339

{{short description|Area codes for Boston suburbs in Massachusetts}}

Area code 781 and 339 are telephone area codes in the North American Numbering Plan for the U.S. state of Massachusetts. The numbering plan area consists of Boston’s inner suburbs along the Route 128 corridor, and some outer suburbs, especially in the South Shore region. Major cities and towns with the area code include Waltham, Woburn, Lynn, Weymouth and Dedham. It was created as in an area code split of area code 617 on September 1, 1997."[https://www.newspapers.com/image/948738770/ Code of Confusion: Phone Company Fears Change Will Hang Us Up]". Associated Press. Daily Evening Item (Lynn, Massachusetts). p. 1. Use of 781 became mandatory February 1, 1998."[https://www.newspapers.com/image/546687746/ New area codes began Sunday]". Associated Press. North Adams Transcript (North Adams, Massachusetts). p. A8. Area code 339 is an overlay complex code for the same service area, activated on May 2, 2001.Howe, Peter J. (March 29, 2001). "[https://www.newspapers.com/image/442962998/ Get Set to Dial 10 Digits: New Rules Start Monday for all Eastern Mass. calls]". Boston Globe. p. A1. Since then, ten-digit dialing has been mandatory.

Some mobile telephone numbers assigned in the 1990s to rate centers in 781 and 339 kept the 617 area code just on those mobile lines after the split.
