BLNGNWGULF prefixes in area code 979

NANPA records 3 assigned NXX blocks to rate center BLNGNWGULF in area code 979, 0.7% of the 413 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 GRANDE COMMUNICATIONS NETWORKS, INC. - TX (1), PEERLESS NETWORK OF TEXAS, LLC - TX (1), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (1). The earliest assignment on record here is 2004-03-08 and the most recent 2004-03-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
