CHICAGOHTS prefixes in area code 708

NANPA records 64 assigned NXX blocks to rate center CHICAGOHTS in area code 708, 8.2% 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. 12 holders hold those blocks, the largest being T-MOBILE USA, INC. (27), ILLINOIS BELL TEL CO (14), NEW CINGULAR WIRELESS PCS, LLC - IL (6). The earliest assignment on record here is 2001-04-02 and the most recent 2024-01-11. 48 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 464 – overlay codes cover the same geography, so a rate center is served by all of them.
