ASPERMONT prefixes in area code 940

NANPA records 3 assigned NXX blocks to rate center ASPERMONT in area code 940, 0.6% of the 506 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1), SANTA ROSA TELEPHONE COOPERATIVE, INC. (1), VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (1). The earliest assignment on record here is 2002-11-25 and the most recent 2004-04-19. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
