ISHPEMING prefixes in area code 906

NANPA records 6 assigned NXX blocks to rate center ISHPEMING in area code 906, 1.7% of the 360 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 MICHIGAN BELL TEL CO (3), NEW CINGULAR WIRELESS PCS, LLC - IL (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (1). The earliest assignment on record here is 2001-05-14 and the most recent 2004-03-19. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
