OMAK prefixes in area code 509

NANPA records 8 assigned NXX blocks to rate center OMAK in area code 509, 1.0% of the 763 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 QWEST CORPORATION (3), NEW CINGULAR WIRELESS PCS, LLC (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (1). The earliest assignment on record here is 2002-04-04 and the most recent 2012-12-14. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
