SOUTHWAYNE prefixes in area code 608

NANPA records 3 assigned NXX blocks to rate center SOUTHWAYNE in area code 608, 0.4% 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 UTELCO, INC. (1), CHARTER IP ENABLED SERVICES, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2017-08-08 and the most recent 2024-03-14. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
