NEWMRTNSVL prefixes in area code 304

NANPA records 7 assigned NXX blocks to rate center NEWMRTNSVL in area code 304, 0.9% of the 785 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 CSC VOICE, LLC (1), FIBERNET, LLC - WV (1), PEERLESS NETWORK OF WEST VIRGINIA, LLC - WV (1). The earliest assignment on record here is 2001-11-19 and the most recent 2002-01-21. 6 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 code 681 – overlay codes cover the same geography, so a rate center is served by all of them.
