COULEE DAM prefixes in area code 509
NANPA records 3 assigned NXX blocks to rate center COULEE DAM in area code 509, 0.4% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - WA (1), NEW CINGULAR WIRELESS PCS, LLC (1), QWEST CORPORATION (1). The earliest assignment on record here is 2001-10-29 and the most recent 2001-10-29. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
