JANESVILLE prefixes in area code 608
NANPA records 45 assigned NXX blocks to rate center JANESVILLE in area code 608, 5.7% 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. 15 holders hold those blocks, the largest being WISCONSIN BELL INC (10), NEW CINGULAR WIRELESS PCS, LLC - IL (8), UNITED STATES CELLULAR - WI (7). The earliest assignment on record here is 2001-01-17 and the most recent 2025-04-23. 31 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 319, 507, 530 – overlay codes cover the same geography, so a rate center is served by all of them.
