GROOM prefixes in area code 806

NANPA records 3 assigned NXX blocks to rate center GROOM in area code 806, 0.4% of the 734 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 (1), CENTURYLINK COMMUNICATIONS, LLC (1), AMA COMM., LLC DBA AMA*TECHTEL COMMUNICATIONS-TX (1). The earliest assignment on record here is 2008-07-21 and the most recent 2017-10-26. 1 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
