SILVER BAY prefixes in area code 218

NANPA records 5 assigned NXX blocks to rate center SILVER BAY in area code 218, 0.7% of the 708 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 QWEST CORPORATION (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MN (1), COMMIO, LLC (1). The earliest assignment on record here is 2003-01-24 and the most recent 2021-04-17. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
