INTETNLFLS prefixes in area code 218

NANPA records 7 assigned NXX blocks to rate center INTETNLFLS in area code 218, 1.0% of the 708 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 CITIZENS TELECOM CO MN-FRONTIER CITIZENS COM-MN (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MN (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2003-11-12 and the most recent 2010-07-27. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
