VIROQUA prefixes in area code 608

NANPA records 5 assigned NXX blocks to rate center VIROQUA in area code 608, 0.6% of the 785 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 UNITED STATES CELLULAR - WI (1), FRONTIER COMMUNICATIONS OF WISCONSIN LLC (1), VERNON COMMUNICATIONS COOPERATIVE (1). The earliest assignment on record here is 2007-07-13 and the most recent 2023-02-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
