WALLER prefixes in area code 936

NANPA records 8 assigned NXX blocks to rate center WALLER in area code 936, 1.9% of the 422 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 SOUTHWESTERN BELL (3), BANDWIDTH.COM CLEC, LLC - TX (2), MATRIX TELECOM, LLC. S/I/I TNCI - TX (1). The earliest assignment on record here is 2001-05-17 and the most recent 2013-01-10. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
