WONEWOC prefixes in area code 608

NANPA records 3 assigned NXX blocks to rate center WONEWOC in area code 608, 0.4% 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. 3 holders hold those blocks, the largest being BRIGHTSPEED OF WESTERN WISCONSIN, LLC (1), ONVOY, LLC - WI (1), MICHIGAN WIRELESS, LLC DBA BUG TUSSEL WIRELESS (1). The earliest assignment on record here is 2009-12-22 and the most recent 2021-07-02. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
