CHAMPAURBN prefixes in area code 217

NANPA records 81 assigned NXX blocks to rate center CHAMPAURBN in area code 217, 10.3% of the 786 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. 21 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (30), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (11), T-MOBILE USA, INC. (10). The earliest assignment on record here is 2001-09-28 and the most recent 2021-02-08. 47 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 447 – overlay codes cover the same geography, so a rate center is served by all of them.
