NEW ROCKFD prefixes in area code 701

NANPA records 4 assigned NXX blocks to rate center NEW ROCKFD in area code 701, 0.5% of the 743 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), NORTH DAKOTA TELEPHONE CO. (1), MIDCONTINENT COMMUNICATIONS - ND (1). The earliest assignment on record here is 2001-07-16 and the most recent 2010-10-27. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
