CICERO prefixes in area code 708

NANPA records 25 assigned NXX blocks to rate center CICERO in area code 708, 3.2% 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (5), ILLINOIS BELL TEL CO (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3). The earliest assignment on record here is 2001-04-12 and the most recent 2024-02-09. 21 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 315, 317, 463, 464 – overlay codes cover the same geography, so a rate center is served by all of them.
