SPOKANE prefixes in area code 509
NANPA records 214 assigned NXX blocks to rate center SPOKANE in area code 509, 28.0% 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. 38 holders hold those blocks, the largest being QWEST CORPORATION (63), ONVOY, LLC - WA (36), NEW CINGULAR WIRELESS PCS, LLC (18). The earliest assignment on record here is 2001-01-30 and the most recent 2025-01-07. 113 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
