MATTOON prefixes in area code 217

NANPA records 24 assigned NXX blocks to rate center MATTOON in area code 217, 3.1% 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. 11 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (6), ILLINOIS CONSOLIDATED TEL. CO. (5), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2005-05-20 and the most recent 2024-12-13. 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 447, 534, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
