WALLIS prefixes in area code 979

NANPA records 6 assigned NXX blocks to rate center WALLIS in area code 979, 1.5% 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TX (2), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1). The earliest assignment on record here is 2001-05-22 and the most recent 2001-10-02. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
