NANPA CO code assignment, current as of July 28, 2026.

The 617-416 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.

The assigned code holder is NEW CINGULAR WIRELESS PCS, LLC - DC, operating company number 4036, assigned February 16, 2001. The prefix is not pooled, so the full 10,000-number block sits with the code holder (subject to number portability).

Caller ID showing 617-416 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.
