Prefix 617-210 — Boston, MA
The 617-210 prefix belongs to area code 617 and is anchored to the Boston rate center (MA). In NANP terms, the prefix — or NXX — determines the rate center a number is billed against.
Boston is part of the Boston-Cambridge-Newton, MA-NH Metropolitan Statistical Area. For routing purposes it sits in LATA 128. Numbers here keep Eastern time.
NANPA's central-office code records list VERIZON NEW ENGLAND INC. (OCN 9102) as the code holder. Because 617-210 participates in thousands-block pooling, individual 1,000-number blocks may belong to other carriers than the code holder.
Caller ID showing 617-210 is not proof the call came from Boston: spoofing and porting both detach numbers from their origin. To verify a caller, hang up and dial the organization's published number, and report suspicious calls to the FTC.
