ROCHELLE prefixes in area code 815

NANPA records 5 assigned NXX blocks to rate center ROCHELLE in area code 815, 0.6% 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. 4 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IL (2), VONAGE AMERICA LLC (1), LEVEL 3 COMMUNICATIONS, LLC - IL (1). The earliest assignment on record here is 2006-11-27 and the most recent 2019-09-30. 3 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 codes 229, 325, 779 – overlay codes cover the same geography, so a rate center is served by all of them.
