DEER PARK prefixes in area code 509

NANPA records 8 assigned NXX blocks to rate center DEER PARK in area code 509, 1.0% 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (3), QWEST CORPORATION (2), CALLWORKS CORPORATION (1). The earliest assignment on record here is 2012-06-13 and the most recent 2026-10-05. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 251, 281, 346, 631 – overlay codes cover the same geography, so a rate center is served by all of them.
