NOCONA prefixes in area code 940

NANPA records 3 assigned NXX blocks to rate center NOCONA in area code 940, 0.6% 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. 2 holders hold those blocks, the largest being TEXAS WINDSTREAM, LLC (2), TELNYX LLC (1). The earliest assignment on record here is 2016-07-15 and the most recent 2016-07-15. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
