BERKELYSPG prefixes in area code 304

NANPA records 4 assigned NXX blocks to rate center BERKELYSPG in area code 304, 0.5% 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - WV (2), FRONTIER WEST VIRGINIA INC. (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2001-11-19 and the most recent 2009-08-17. 3 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.
