WILLIAMSTN prefixes in area code 304
NANPA records 3 assigned NXX blocks to rate center WILLIAMSTN in area code 304, 0.4% 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 T-MOBILE USA, INC. (1), FRONTIER WEST VIRGINIA INC. (1), CSC VOICE, LLC (1). 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 codes 252, 315, 413, 517 – overlay codes cover the same geography, so a rate center is served by all of them.
