NEW RICHLD prefixes in area code 507

NANPA records 4 assigned NXX blocks to rate center NEW RICHLD in area code 507, 0.5% of the 766 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 ONVOY, LLC - MN (1), ONVOY SPECTRUM, LLC (1), CENTURYLINK OF MINNESOTA, INC. (1). The earliest assignment on record here is 2004-05-10 and the most recent 2022-03-24. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
