ST IGNACE prefixes in area code 906

NANPA records 6 assigned NXX blocks to rate center ST IGNACE 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. 6 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (1), INTERACTIVE SERVICES NETWORK, INC. (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-05-21 and the most recent 2003-07-28. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
