OCONTO FLS prefixes in area code 920

NANPA records 4 assigned NXX blocks to rate center OCONTO FLS 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 PLTC, LLC - WI (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), BRIGHTSPEED OF NORTH CENTRAL WISCONSIN, LLC (1). The earliest assignment on record here is 2013-02-13 and the most recent 2013-02-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
