ROXBURY prefixes in area code 617

NANPA records 16 assigned NXX blocks to rate center ROXBURY in area code 617, 2.1% 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. 8 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4), OMNIPOINT MIAMI E LICENSE, LLC (2). The earliest assignment on record here is 2009-03-31 and the most recent 2009-03-31. 9 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 607, 785, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
