AU GRES prefixes in area code 989

NANPA records 4 assigned NXX blocks to rate center AU GRES in area code 989, 0.6% of the 723 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 NEW CINGULAR WIRELESS PCS, LLC - IL (2), INTERACTIVE SERVICES NETWORK, INC. (1), BRIGHTSPEED OF CENTRAL MICHIGAN, INC (1). The earliest assignment on record here is 2004-03-05 and the most recent 2005-09-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
