LA CROSSE prefixes in area code 608

NANPA records 41 assigned NXX blocks to rate center LA CROSSE in area code 608, 5.2% 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. 11 holders hold those blocks, the largest being BRIGHTSPEED OF WISCONSIN, LLC (15), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (7), UNITED STATES CELLULAR - WI (4). The earliest assignment on record here is 2001-04-01 and the most recent 2023-07-26. 23 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 219, 434, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
