SERGENTBLF prefixes in area code 712
NANPA records 13 assigned NXX blocks to rate center SERGENTBLF in area code 712, 2.1% of the 633 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 NORTHWEST IOWA TELEPHONE, LLC (11), LEVEL 3 COMMUNICATIONS, LLC - IA (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-07-06 and the most recent 2008-01-22. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
