APOLLO prefixes in area code 281

NANPA records 28 assigned NXX blocks to rate center APOLLO in area code 281, 3.6% 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. 8 holders hold those blocks, the largest being SOUTHWESTERN BELL (17), ONVOY, LLC - TX (3), TELEPORT COMMUNICATIONS AMERICA, LLC - TX (2). The earliest assignment on record here is 2002-01-07 and the most recent 2002-01-07. 17 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 346, 713, 724, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
