PASCO prefixes in area code 509
NANPA records 26 assigned NXX blocks to rate center PASCO in area code 509, 3.4% 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (8), QWEST CORPORATION (6), METROPCS, INC. (3). The earliest assignment on record here is 2001-12-11 and the most recent 2025-08-29. 17 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
