REEDSBURG prefixes in area code 608

NANPA records 7 assigned NXX blocks to rate center REEDSBURG 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. 6 holders hold those blocks, the largest being ONVOY, LLC - WI (2), UNITED STATES CELLULAR - WI (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (1). The earliest assignment on record here is 2003-07-10 and the most recent 2025-05-23. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
