SUPERIOR prefixes in area code 715

NANPA records 11 assigned NXX blocks to rate center SUPERIOR in area code 715, 1.4% 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. 6 holders hold those blocks, the largest being BRIGHTSPEED OF NORTH CENTRAL WISCONSIN, LLC (5), AERIAL COMMUNICATIONS, INC. (2), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2002-05-30 and the most recent 2014-09-10. 8 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 402, 406, 520, 531 – overlay codes cover the same geography, so a rate center is served by all of them.
