GOLDENDALE prefixes in area code 509

NANPA records 4 assigned NXX blocks to rate center GOLDENDALE in area code 509, 0.5% 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (1), UNITED STATES CELLULAR - WA (1), TELEPORT COMMUNICATIONS AMERICA, LLC - WA (1). The earliest assignment on record here is 2002-05-31 and the most recent 2002-05-31. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
