CARTERVL prefixes in area code 618

NANPA records 4 assigned NXX blocks to rate center CARTERVL in area code 618, 0.5% 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), MEDIACOM TELEPHONY OF ILLINOIS, LLC - IL (1), MCC NETWORK SERVICES, LLC (1). The earliest assignment on record here is 2002-04-02 and the most recent 2005-03-29. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
