HUGHES SPG prefixes in area code 903

NANPA records 3 assigned NXX blocks to rate center HUGHES SPG in area code 903, 0.4% of the 771 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. 2 holders hold those blocks, the largest being VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), CSC VOICE, LLC (1). The earliest assignment on record here is 2015-02-18 and the most recent 2015-02-18. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 430 – overlay codes cover the same geography, so a rate center is served by all of them.
