NACOGDOCHS prefixes in area code 936

NANPA records 28 assigned NXX blocks to rate center NACOGDOCHS in area code 936, 6.6% 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. 9 holders hold those blocks, the largest being SOUTHWESTERN BELL (10), NEW CINGULAR WIRELESS PCS, LLC - IL (6), LEVEL 3 COMMUNICATIONS, LLC - TX (4). The earliest assignment on record here is 2002-03-28 and the most recent 2014-04-10. 17 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
