WINAMAC prefixes in area code 574

NANPA records 5 assigned NXX blocks to rate center WINAMAC in area code 574, 1.2% of the 403 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 NEW CINGULAR WIRELESS PCS, LLC - IL (2), LEVEL 3 COMMUNICATIONS, LLC - IN (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IN (1). The earliest assignment on record here is 2002-07-23 and the most recent 2009-12-21. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
