CARO prefixes in area code 989
NANPA records 8 assigned NXX blocks to rate center CARO in area code 989, 1.1% 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. 7 holders hold those blocks, the largest being BRIGHTSPEED OF MICHIGAN, LLC (2), INTERACTIVE SERVICES NETWORK, INC. (1), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (1). The earliest assignment on record here is 2004-03-25 and the most recent 2023-03-07. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
