ONSTED prefixes in area code 517
NANPA records 4 assigned NXX blocks to rate center ONSTED in area code 517, 0.6% 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. 4 holders hold those blocks, the largest being ONVOY, LLCV - MI (1), DEERFIELD FARMERS' TELEPHONE COMPANY - MI (1), FRONTIER COMMUNICATIONS OF MICHIGAN, INC. (1). The earliest assignment on record here is 2019-10-10 and the most recent 2021-05-19. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
