- L2: FCC-reported (used on this page). Providers report the technology at each location to the FCC National Broadband Map.
- L3: Provider-coverage (used on this page). Optimum names the place on its own locations page (shown as "Listed by Optimum").

- L5: User-confirmed orderable. We never claim this level. You confirm it when you place the order.
Deciding in Idaho
- Grangeville: ask Optimum for the download and upload speeds at your address before you order.
- Spirit Lake, Kellogg or Orofino: other companies report fiber at more than eight in ten homes (83.7% in Kellogg). Put a fiber plan next to Optimum's cable.
- Rathdrum or Kamiah: FCC shows no Optimum inside either town, so start with the other companies.
- Wallace: with fewer companies in town, compare every offer you get.
