HSTNSUBURB prefixes in area code 832

NANPA records 53 assigned NXX blocks to rate center HSTNSUBURB in area code 832, 6.7% of the 786 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. 14 holders hold those blocks, the largest being AERIAL COMMUNICATIONS, INC. (13), SOUTHWESTERN BELL (10), ONVOY, LLC - TX (6). The earliest assignment on record here is 2001-01-04 and the most recent 2022-05-04. 50 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 codes 281, 346, 713 – overlay codes cover the same geography, so a rate center is served by all of them.
