BEAVERTON prefixes in area code 503
NANPA records 107 assigned NXX blocks to rate center BEAVERTON in area code 503, 13.6% 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. 10 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (59), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (12), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (11). The earliest assignment on record here is 2004-10-04 and the most recent 2009-03-02. 49 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 971, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
