Area codes 781 and 339
Area code 781 covers most of Boston‘s inner suburbs (the Route 128 corridor) and some outer suburbs (especially in the South Shore region). It was created as a split from area code 617 on September 1, 1997 (LATA code 128). Use of 781 became mandatory February 1, 1998. Area code 339 has been sharing the service area since May 2, 2001. Since then, 10 digit local dialing is mandatory.

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

gollark: Markdown is so weird and annoying to parse.
gollark: Anyway, by perpetuating the "GB is base 2" thing, you aid the confusion which allows HDD makers to ship mildly less storage than they otherwise might, and which is generally kind of irritating if you need precise units in things.
gollark: If we amputate 8 fingers from all humans by force, we will finally enter a golden age of binary prefixes.
gollark: Specialized binary prefixes let you use base 2 if you want to for some reason but use the more consistent and easier to manipulate base 10.
gollark: Programmers like base 2, but all other stuff is mostly done in base 10 and the prefixes were designed around that.
