EATON RPD prefixes in area code 517

NANPA records 7 assigned NXX blocks to rate center EATON RPD in area code 517, 1.1% of the 616 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. 6 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC - MI (2), TON80 COMMUNICATIONS, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - MI (1). The earliest assignment on record here is 2001-11-15 and the most recent 2022-02-22. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
