Where Fidium Fiber is actually available
Fidium Fiber reports service across 18 states and 73 metro areas in the latest FCC filing, and 1,033,779 of its 1,631,878 residential locations are fiber. Here is where that footprint actually reaches, and where it does not.
Is Fidium Fiber available in my area?
Fidium Fiber is a regional network, not a national one. The honest answer for any given home is that it depends on the street, because fiber networks were built out block by block. The tables below are the closest thing to a straight answer that public federal data allows: every state and metro where Fidium Fiber has reported service, and how much of each it covers.
Fidium Fiber coverage by state
These percentages are the whole Fidium Fiber network, not just fiber. 63.3% of what this operator files with the FCC is fiber (1,033,779 residential locations); the rest is DSL / copper (595,745), cable (2,353) and other (1). The FCC publishes that split for the country as a whole and never by state or metro, so no public source can say how much of any one state is fiber. Read the table below as where this operator reports service on any fixed technology.
Coverage is the share of residential locations in each state where Fidium Fiber reports it can serve. A low percentage does not mean a bad network. It usually means a network concentrated in a few towns.
| State | Share of homes covered |
|---|---|
| New Hampshire | 72.8% |
| Vermont | 66.1% |
| Maine | 65.8% |
| North Dakota | 2.5% |

What technology does Fidium Fiber use?
Fidium Holdings, LLC reports more than one technology to the FCC, so not every address in its footprint gets the same product:
63% of the locations Fidium Holdings, LLC reports nationally are fiber.
| Technology | Residential locations reported |
|---|---|
| Fiber | 1,033,779 |
| DSL / Copper | 595,745 |
| Cable | 2,353 |
| Other | 1 |
An honest limitation. The FCC publishes each provider's technology mix nationally, but not per city. So we can tell you Fidium Fiber operates fiber somewhere in a given state and we cannot tell you from this data that your particular street gets fiber rather than one of the others. Check with the provider before signing anything.

Common questions
Is Fidium Fiber available at my address?
Only an address check answers that. Use the state and metro tables above to find out whether Fidium Fiber operates in your area at all. If your state is not listed, it does not. If it is, coverage within that state is uneven and street-level.
Who owns Fidium Fiber?
Fidium Fiber files with the FCC under the holding company name Fidium Holdings, LLC. This is common, because the name on the bill and the name on the federal filing are frequently different.
How current is this data?
It comes from the FCC Broadband Data Collection, filing period D25, published July 21, 2026. The FCC refreshes it roughly twice a year, and there is a publication lag of several months. We update these pages when new data is released.
Does WhereFiber earn money if I sign up?
Sometimes. Where a provider runs an affiliate program we may earn a commission, at no extra cost to you. It does not affect which providers appear here, which is decided by FCC data alone. Full detail in our affiliate disclosure.
