WHITECLOUD prefixes in area code 231
NANPA records 4 assigned NXX blocks to rate center WHITECLOUD in area code 231, 0.7% of the 572 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), MICHIGAN BELL TEL CO (1), ONVOY, LLCV - MI (1). The earliest assignment on record here is 2014-11-07 and the most recent 2021-05-13. 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 785 – overlay codes cover the same geography, so a rate center is served by all of them.
