CHARLES CY prefixes in area code 641

NANPA records 11 assigned NXX blocks to rate center CHARLES CY in area code 641, 1.9% of the 584 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (2), QWEST CORPORATION (2), OMNITEL COMMUNICATIONS, INC. - IA (2). The earliest assignment on record here is 2005-05-13 and the most recent 2020-12-09. 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 686, 804 – overlay codes cover the same geography, so a rate center is served by all of them.
