CHEWELAH prefixes in area code 509

NANPA records 5 assigned NXX blocks to rate center CHEWELAH in area code 509, 0.7% 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 CENTURYTEL OF WASHINGTON, INC. DBA CENTURYLINK (3), BOOST SUBSCRIBERCO L.L.C. (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (1). The earliest assignment on record here is 2022-08-02 and the most recent 2022-08-02. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
