MARINETTE prefixes in area code 715

NANPA records 10 assigned NXX blocks to rate center MARINETTE in area code 715, 1.3% of the 785 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. 7 holders hold those blocks, the largest being NEW CELL DBA CELLCOM (3), BRIGHTSPEED OF NORTH CENTRAL WISCONSIN, LLC (2), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2002-10-31 and the most recent 2020-11-19. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
