WAUKON prefixes in area code 563

NANPA records 5 assigned NXX blocks to rate center WAUKON in area code 563, 1.3% 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. 5 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - IA (1), ONVOY, LLC - IA (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2007-09-19 and the most recent 2021-06-21. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
