LONGPRAIRI prefixes in area code 320

NANPA records 4 assigned NXX blocks to rate center LONGPRAIRI in area code 320, 0.8% of the 511 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 LEVEL 3 COMMUNICATIONS, LLC - MN (1), ONVOY, LLC - MN (1), CENTURYLINK OF MINNESOTA, INC. (1). The earliest assignment on record here is 2004-04-06 and the most recent 2008-10-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
