GLENVIEW prefixes in area code 224

NANPA records 14 assigned NXX blocks to rate center GLENVIEW in area code 224, 2.4% 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. 6 holders hold those blocks, the largest being T-MOBILE USA, INC. (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (4), FRACTEL, LLC (1). The earliest assignment on record here is 2001-11-13 and the most recent 2024-03-07. 14 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.
