CLINTON prefixes in area code 563

NANPA records 18 assigned NXX blocks to rate center CLINTON in area code 563, 4.6% of the 388 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 QWEST CORPORATION (5), UNITED STATES CELLULAR - IA (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2). The earliest assignment on record here is 2001-01-04 and the most recent 2024-02-09. 13 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 207, 217, 225, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
