COLVILLE prefixes in area code 509

NANPA records 8 assigned NXX blocks to rate center COLVILLE 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (2), QWEST CORPORATION (2). The earliest assignment on record here is 2002-04-04 and the most recent 2002-04-04. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
