ALGONQUIN prefixes in area code 847

NANPA records 7 assigned NXX blocks to rate center ALGONQUIN in area code 847, 0.9% 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. 3 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (4), LEVEL 3 COMMUNICATIONS, LLC - IL (2), RCN TELECOM SERVICES OF ILLINIOS, INC. - IL (1). The earliest assignment on record here is 2008-05-13 and the most recent 2008-05-13. 5 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 224 – overlay codes cover the same geography, so a rate center is served by all of them.
