SO BOSTON prefixes in area code 434
NANPA records 13 assigned NXX blocks to rate center SO BOSTON in area code 434, 2.6% of the 509 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 BRIGHTSPEED OF VIRGINIA, LLC (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - VA (2), METROPCS, INC. (2). The earliest assignment on record here is 2002-05-20 and the most recent 2023-03-17. 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 617, 857 – overlay codes cover the same geography, so a rate center is served by all of them.
