WAUSAU prefixes in area code 715

NANPA records 35 assigned NXX blocks to rate center WAUSAU in area code 715, 4.5% 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. 10 holders hold those blocks, the largest being FRONTIER NORTH INC. - WI (16), NEW CINGULAR WIRELESS PCS, LLC - IL (5), NEW CELL DBA CELLCOM (5). The earliest assignment on record here is 2001-04-09 and the most recent 2021-04-28. 14 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 code 534 – overlay codes cover the same geography, so a rate center is served by all of them.
