SKOKIE prefixes in area code 224

NANPA records 13 assigned NXX blocks to rate center SKOKIE in area code 224, 2.2% of the 595 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. 8 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (2), ONVOY, LLC (2). The earliest assignment on record here is 2006-03-29 and the most recent 2024-01-24. 13 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 847 – overlay codes cover the same geography, so a rate center is served by all of them.
