STILWELL prefixes in area code 918

NANPA records 6 assigned NXX blocks to rate center STILWELL in area code 918, 0.8% of the 782 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. 3 holders hold those blocks, the largest being OKLAHOMA WINDSTREAM, INC. (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OK (1). The earliest assignment on record here is 2002-09-30 and the most recent 2005-09-26. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
