HOOD LAND prefixes in area code 503

NANPA records 3 assigned NXX blocks to rate center HOOD LAND in area code 503, 0.4% 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. 3 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - OR (1), ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (1), ONVOY, LLC - OR (1). The earliest assignment on record here is 2005-01-28 and the most recent 2006-11-15. 3 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 code 971 – overlay codes cover the same geography, so a rate center is served by all of them.
