COOPERSVL prefixes in area code 616

NANPA records 5 assigned NXX blocks to rate center COOPERSVL in area code 616, 0.9% of the 545 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. 5 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (1), ONVOY, LLCV - MI (1), ACD TELECOM, INC. - MI (1). The earliest assignment on record here is 2004-09-29 and the most recent 2022-01-21. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
