CENTERLINE prefixes in area code 586
NANPA records 43 assigned NXX blocks to rate center CENTERLINE in area code 586, 7.9% of the 546 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. 11 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (21), TELEPORT COMMUNICATIONS AMERICA, LLC - MI (4), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (4). The earliest assignment on record here is 2008-11-03 and the most recent 2025-06-11. 29 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
