HSTNSUBURB prefixes in area code 713
NANPA records 20 assigned NXX blocks to rate center HSTNSUBURB in area code 713, 2.5% of the 785 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 SOUTHWESTERN BELL (12), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (2), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (2). The earliest assignment on record here is 2007-08-22 and the most recent 2023-07-05. 13 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, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
