RISINGSTAR prefixes in area code 254

NANPA records 4 assigned NXX blocks to rate center RISINGSTAR in area code 254, 0.6% of the 672 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, LD-TX #2 DBA WINDSTREAM COMM SW (2), AMA COMM., LLC DBA AMA*TECHTEL COMMUNICATIONS-TX (1), LEVEL 3 COMMUNICATIONS, LLC - TX (1). The earliest assignment on record here is 2010-05-10 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.
