DECATUR prefixes in area code 217

NANPA records 44 assigned NXX blocks to rate center DECATUR in area code 217, 5.6% 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. 8 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (18), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (7), NEW CINGULAR WIRELESS PCS, LLC - IL (7). The earliest assignment on record here is 2001-03-13 and the most recent 2019-05-17. 25 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 256, 260, 269, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
