WAUKEGAN prefixes in area code 224

NANPA records 38 assigned NXX blocks to rate center WAUKEGAN in area code 224, 6.4% 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. 12 holders hold those blocks, the largest being T-MOBILE USA, INC. (10), NEW CINGULAR WIRELESS PCS, LLC - IL (7), ILLINOIS BELL TEL CO (7). The earliest assignment on record here is 2001-11-13 and the most recent 2024-10-22. 38 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.
