FORSAN prefixes in area code 432

NANPA records 4 assigned NXX blocks to rate center FORSAN 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. 3 holders hold those blocks, the largest being VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), ONVOY, LLC - TX (1), AMA COMM., LLC DBA AMA*TECHTEL COMMUNICATIONS-TX (1). The earliest assignment on record here is 2016-11-16 and the most recent 2018-01-19. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
