TOMBALL prefixes in area code 832

NANPA records 10 assigned NXX blocks to rate center TOMBALL in area code 832, 1.3% 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. 7 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TX (2), SOUTHWESTERN BELL (2), LEVEL 3 OF TELECOM OF TEXAS, LLC - TX (2). The earliest assignment on record here is 2001-02-02 and the most recent 2014-10-08. 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 codes 281, 346, 713 – overlay codes cover the same geography, so a rate center is served by all of them.
