SATSUMA prefixes in area code 281

NANPA records 18 assigned NXX blocks to rate center SATSUMA in area code 281, 2.3% 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 SOUTHWESTERN BELL (9), LEVEL 3 OF TELECOM OF TEXAS, LLC - TX (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - TX (2). The earliest assignment on record here is 2009-03-18 and the most recent 2010-04-22. 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 346, 832 – overlay codes cover the same geography, so a rate center is served by all of them.
