KINROSS prefixes in area code 906

NANPA records 4 assigned NXX blocks to rate center KINROSS in area code 906, 1.1% of the 360 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. 4 holders hold those blocks, the largest being CHARTER IP ENABLED SERVICES, LLC (1), ONVOY, LLCV - MI (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2005-03-25 and the most recent 2012-09-26. 2 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 319 – overlay codes cover the same geography, so a rate center is served by all of them.
