COOS BAY prefixes in area code 541
NANPA records 16 assigned NXX blocks to rate center COOS BAY in area code 541, 2.0% 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 ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (4), UNITED STATES CELLULAR - OR (3), NEW CINGULAR WIRELESS PCS, LLC (2). The earliest assignment on record here is 2001-01-19 and the most recent 2008-04-15. 9 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.
