MORGANTOWN prefixes in area code 304

NANPA records 33 assigned NXX blocks to rate center MORGANTOWN in area code 304, 4.2% 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. 15 holders hold those blocks, the largest being FRONTIER WEST VIRGINIA INC. (10), NEW CINGULAR WIRELESS PCS, LLC - IL (4), UNITED STATES CELLULAR - WV (4). The earliest assignment on record here is 2001-07-16 and the most recent 2017-01-25. 22 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 270, 610, 681, 812 – overlay codes cover the same geography, so a rate center is served by all of them.
