BELOIT prefixes in area code 608

NANPA records 25 assigned NXX blocks to rate center BELOIT in area code 608, 3.2% 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. 14 holders hold those blocks, the largest being WISCONSIN BELL INC (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-02-15 and the most recent 2025-08-21. 20 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 712, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
