KIEL prefixes in area code 920

NANPA records 4 assigned NXX blocks to rate center KIEL in area code 920, 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 UNITED STATES CELLULAR - WI (1), NEW CELL DBA CELLCOM (1), LEVEL 3 COMMUNICATIONS, LLC - WI (1). The earliest assignment on record here is 2002-08-21 and the most recent 2003-02-27. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
