QUINCY prefixes in area code 217

NANPA records 25 assigned NXX blocks to rate center QUINCY in area code 217, 3.2% 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. 9 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (8), UNITED STATES CELLULAR - IL (4), NEW CINGULAR WIRELESS PCS, LLC - IL (4). The earliest assignment on record here is 2001-04-27 and the most recent 2016-05-05. 16 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, 448, 509, 517 – overlay codes cover the same geography, so a rate center is served by all of them.
