STEPHEN prefixes in area code 218

NANPA records 3 assigned NXX blocks to rate center STEPHEN in area code 218, 0.4% 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. 3 holders hold those blocks, the largest being CITIZENS TELECOM CO MN-FRONTIER CITIZENS COM-MN (1), WIKSTROM TELEPHONE COMPANY, INC. - MN (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2010-05-03 and the most recent 2010-05-03. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
