MAQUOKETA prefixes in area code 563

NANPA records 4 assigned NXX blocks to rate center MAQUOKETA in area code 563, 1.0% 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. 4 holders hold those blocks, the largest being CENTURYLINK COMMUNICATIONS, LLC (1), QWEST CORPORATION (1), ONVOY, LLC - IA (1). The earliest assignment on record here is 2007-12-07 and the most recent 2016-09-21. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
