RIVERGROVE prefixes in area code 708

NANPA records 14 assigned NXX blocks to rate center RIVERGROVE in area code 708, 1.8% of the 784 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 (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), LEVEL 3 COMMUNICATIONS, LLC - IL (2). The earliest assignment on record here is 2001-04-12 and the most recent 2001-04-12. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
