CHILDRESS prefixes in area code 940

NANPA records 6 assigned NXX blocks to rate center CHILDRESS in area code 940, 1.2% 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 LEVEL 3 COMMUNICATIONS, LLC - TX (1), T-MOBILE USA, INC. (1), ONVOY, LLC - TX (1). The earliest assignment on record here is 2002-07-19 and the most recent 2016-11-14. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
