CHESANING prefixes in area code 989

NANPA records 4 assigned NXX blocks to rate center CHESANING 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), INTERACTIVE SERVICES NETWORK, INC. (1), BRIGHTSPEED OF CENTRAL MICHIGAN, INC (1). The earliest assignment on record here is 2003-08-01 and the most recent 2004-12-06. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
