HINCKLEY prefixes in area code 320

NANPA records 7 assigned NXX blocks to rate center HINCKLEY in area code 320, 1.4% of the 511 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. 6 holders hold those blocks, the largest being AERIAL COMMUNICATIONS, INC. (2), ONVOY, LLC - MN (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2002-02-12 and the most recent 2008-10-21. 7 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 234, 330, 779, 815 – overlay codes cover the same geography, so a rate center is served by all of them.
