BRILLION prefixes in area code 920

NANPA records 5 assigned NXX blocks to rate center BRILLION in area code 920, 0.6% 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 FRONTIER NORTH INC. - WI (2), LEVEL 3 COMMUNICATIONS, LLC - WI (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (1). The earliest assignment on record here is 2001-06-08 and the most recent 2003-12-01. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
