BLCKRIVFLS prefixes in area code 715

NANPA records 4 assigned NXX blocks to rate center BLCKRIVFLS in area code 715, 0.5% 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. 4 holders hold those blocks, the largest being BRIGHTSPEED OF CENTRAL WISCONSIN, LLC (1), UNITED STATES CELLULAR - WI (1), CHARTER IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2003-08-08 and the most recent 2005-12-08. 4 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.
