SUNNYSIDE prefixes in area code 509
NANPA records 15 assigned NXX blocks to rate center SUNNYSIDE in area code 509, 2.0% 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. 8 holders hold those blocks, the largest being T-MOBILE USA, INC. (3), UNITED TELEPHONE - NORTHWEST DBA CENTURYLINK - WA (3), NEW CINGULAR WIRELESS PCS, LLC (2). The earliest assignment on record here is 2002-09-19 and the most recent 2021-04-16. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
