NIXA prefixes in area code 417

NANPA records 7 assigned NXX blocks to rate center NIXA in area code 417, 1.0% of the 711 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 CSC VOICE, LLC (2), SOUTHWESTERN BELL (2), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2002-05-06 and the most recent 2013-11-04. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
