BOSTON prefixes in area code 617
NANPA records 274 assigned NXX blocks to rate center BOSTON in area code 617, 35.7% of the 768 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 17 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (131), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (30), NEW CINGULAR WIRELESS PCS, LLC - DC (23). The earliest assignment on record here is 2001-02-16 and the most recent 2025-03-18. 111 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 229, 716, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
