CORVALLIS prefixes in area code 541

NANPA records 30 assigned NXX blocks to rate center CORVALLIS in area code 541, 3.8% of the 783 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. 9 holders hold those blocks, the largest being QWEST CORPORATION (14), T-MOBILE USA, INC. (4), LEVEL 3 COMMUNICATIONS, LLC - OR (3). The earliest assignment on record here is 2002-05-03 and the most recent 2003-12-12. 16 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 458 – overlay codes cover the same geography, so a rate center is served by all of them.
