BRIGGSVL prefixes in area code 608

NANPA records 4 assigned NXX blocks to rate center BRIGGSVL in area code 608, 0.5% 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 FRONTIER NORTH INC. - WI (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (1), METROPCS, INC. (1). The earliest assignment on record here is 2001-05-11 and the most recent 2025-02-28. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
