BRIDGEPORT prefixes in area code 304

NANPA records 6 assigned NXX blocks to rate center BRIDGEPORT in area code 304, 0.8% 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. 5 holders hold those blocks, the largest being FRONTIER WEST VIRGINIA INC. (2), GATEWAY TELECOM LLC DBA STRATUSWAVE COMM LLC WV (1), COMMUNICATIONS PLUS, INC. - WV (1). The earliest assignment on record here is 2002-09-17 and the most recent 2008-03-04. 5 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 203, 256, 308, 315 – overlay codes cover the same geography, so a rate center is served by all of them.
