SISTER BAY prefixes in area code 920
NANPA records 3 assigned NXX blocks to rate center SISTER BAY in area code 920, 0.4% of the 785 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. 3 holders hold those blocks, the largest being MICHIGAN WIRELESS, LLC DBA BUG TUSSEL WIRELESS (1), ONVOY, LLC - WI (1), FRONTIER NORTH INC. - WI (1). The earliest assignment on record here is 2009-05-21 and the most recent 2021-07-26. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
