MINOOKA prefixes in area code 815

NANPA records 8 assigned NXX blocks to rate center MINOOKA in area code 815, 1.0% 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. 7 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (2), BANDWIDTH.COM CLEC, LLC - IL (1), PAETEC ITEL, LLC (1). The earliest assignment on record here is 2001-08-22 and the most recent 2018-10-31. 7 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 779 – overlay codes cover the same geography, so a rate center is served by all of them.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
