ARGOS prefixes in area code 574

NANPA records 4 assigned NXX blocks to rate center ARGOS in area code 574, 1.0% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), LEVEL 3 COMMUNICATIONS, LLC - IN (1), BRIGHTSPEED OF INDIANA, LLC (1). The earliest assignment on record here is 2002-07-23 and the most recent 2002-07-23. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
