SO BOSTON prefixes in area code 617
NANPA records 13 assigned NXX blocks to rate center SO BOSTON in area code 617, 1.7% 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. 7 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), LEVEL 3 COMMUNICATIONS, LLC - MA (2). The earliest assignment on record here is 2002-02-27 and the most recent 2002-02-27. 11 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 434, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
