SUNPRAIRIE prefixes in area code 608
NANPA records 7 assigned NXX blocks to rate center SUNPRAIRIE in area code 608, 0.9% 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. 4 holders hold those blocks, the largest being FRONTIER NORTH INC. - WI (3), ONVOY, LLC - WI (2), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2004-02-03 and the most recent 2024-06-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
