GIBSONCITY prefixes in area code 217

NANPA records 5 assigned NXX blocks to rate center GIBSONCITY in area code 217, 0.6% 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - IL (2), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-10-16 and the most recent 2009-12-18. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
