MOSES LAKE prefixes in area code 509

NANPA records 19 assigned NXX blocks to rate center MOSES LAKE in area code 509, 2.5% 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. 10 holders hold those blocks, the largest being QWEST CORPORATION (6), T-MOBILE USA, INC. (3), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-05-03 and the most recent 2022-08-09. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
