FLOURBLUFF prefixes in area code 361

NANPA records 9 assigned NXX blocks to rate center FLOURBLUFF in area code 361, 1.7% of the 538 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), AT&T - LOCAL (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2002-05-08 and the most recent 2009-10-14. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
