RICHLD CTR prefixes in area code 608
NANPA records 7 assigned NXX blocks to rate center RICHLD CTR 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 FRONTIER NORTH INC. - WI (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1). The earliest assignment on record here is 2001-05-11 and the most recent 2025-01-23. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
