BROOKINGS prefixes in area code 541

NANPA records 7 assigned NXX blocks to rate center BROOKINGS in area code 541, 0.9% 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. 6 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (2), UNITED STATES CELLULAR - OR (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OR (1). The earliest assignment on record here is 2001-02-16 and the most recent 2024-08-15. 5 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 458, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
