COOK prefixes in area code 218
NANPA records 4 assigned NXX blocks to rate center COOK in area code 218, 0.6% of the 708 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - MN (2), ONVOY, LLC - MN (1), QWEST CORPORATION (1). The earliest assignment on record here is 2003-04-30 and the most recent 2022-01-20. 4 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 402 – overlay codes cover the same geography, so a rate center is served by all of them.
