WALLAWALLA prefixes in area code 509

NANPA records 23 assigned NXX blocks to rate center WALLAWALLA in area code 509, 3.0% 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. 11 holders hold those blocks, the largest being QWEST CORPORATION (7), T-MOBILE USA, INC. (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (3). The earliest assignment on record here is 2001-12-11 and the most recent 2024-11-18. 16 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
