MARION prefixes in area code 618

NANPA records 15 assigned NXX blocks to rate center MARION in area code 618, 1.9% 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. 8 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IL (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (3), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2001-09-04 and the most recent 2018-10-03. 11 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 codes 220, 223, 231, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
