BURKBURNTT prefixes in area code 940

NANPA records 10 assigned NXX blocks to rate center BURKBURNTT in area code 940, 2.0% of the 506 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. 6 holders hold those blocks, the largest being ONVOY, LLC - TX (3), CHOICE WIRELESS, LC (3), BANDWIDTH.COM CLEC, LLC - TX (1). The earliest assignment on record here is 2006-07-27 and the most recent 2024-03-22. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
