APPLERIVER prefixes in area code 815

NANPA records 3 assigned NXX blocks to rate center APPLERIVER in area code 815, 0.4% of the 786 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. 2 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IL (2), AERO NORTH COMMUNICATIONS, INC. - IL (1). 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
