HOBBS prefixes in area code 575

NANPA records 28 assigned NXX blocks to rate center HOBBS in area code 575, 5.4% of the 521 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. 10 holders hold those blocks, the largest being VALOR TELECOM TX,LP-NM #1 DBA WINDSTREAM COMM SW (8), NEW CINGULAR WIRELESS PCS, LLC - IL (5), LEACO RURAL TELEPHONE COOPERATIVE, INC. DBA LEACO (4). The earliest assignment on record here is 2001-07-17 and the most recent 2025-03-11. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
