WOODBURN prefixes in area code 503

NANPA records 8 assigned NXX blocks to rate center WOODBURN in area code 503, 1.0% of the 784 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 QWEST CORPORATION (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (2), ASTOUND BROADBAND, LLC - OR (1). The earliest assignment on record here is 2009-06-03 and the most recent 2009-06-03. 6 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 260, 270, 618, 730 – overlay codes cover the same geography, so a rate center is served by all of them.
