BYROMVILLE prefixes in area code 478

NANPA records 4 assigned NXX blocks to rate center BYROMVILLE in area code 478, 0.9% of the 446 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - GA (2), SOUTHERN COMMUNICATIONS SERVICES, INC. (1), WINDSTREAM GEORGIA COMMUNICATIONS CORP. (1). The earliest assignment on record here is 2003-07-08 and the most recent 2008-06-17. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
