COYANOSA prefixes in area code 432

NANPA records 4 assigned NXX blocks to rate center COYANOSA in area code 432, 1.2% of the 341 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. 4 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - TX (1), VALOR TELECOMM TX, LD-TX #2 DBA WINDSTREAM COMM SW (1), AMA COMM., LLC DBA AMA*TECHTEL COMMUNICATIONS-TX (1). The earliest assignment on record here is 2011-05-25 and the most recent 2021-05-06. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
