HONDO prefixes in area code 830

NANPA records 9 assigned NXX blocks to rate center HONDO in area code 830, 1.8% of the 496 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), SOUTHWESTERN BELL (2), ONVOY, LLC - TX (1). The earliest assignment on record here is 2002-03-28 and the most recent 2022-10-31. 9 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 575 – overlay codes cover the same geography, so a rate center is served by all of them.
