BAKER prefixes in area code 541

NANPA records 9 assigned NXX blocks to rate center BAKER in area code 541, 1.1% 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. 7 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - OR (2), QWEST CORPORATION (2), UNITED STATES CELLULAR - OR (1). The earliest assignment on record here is 2001-03-22 and the most recent 2017-12-11. 7 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 406, 442, 458, 760 – overlay codes cover the same geography, so a rate center is served by all of them.
