About WhereFiber
Last updated: July 30, 2026
WhereFiber exists to answer one question properly: which internet providers actually serve a given address in the United States, and what technology do they use to get there?
Why the site exists
Internet providers publish coverage information about themselves and nobody else. Ask any one of them what your options are and you will get a list of one. That leaves households comparing across half a dozen separate websites, each of which wants an address before it will say anything useful.
Fiber makes this worse rather than better. Fiber networks were built out incrementally over many years, so coverage is genuinely street-level. Two homes a few hundred feet apart can have entirely different choices. There is no substitute for checking a specific address.
Where our data comes from
Our availability information is built on the FCC National Broadband Map, produced through the Federal Communications Commission's Broadband Data Collection program. Internet providers are required to report the locations they serve, the technologies they use, and the speeds they offer. The FCC publishes the resulting dataset for public use.
We supplement that with publicly available provider documentation where it helps explain what a service actually involves.
How current it is
The FCC refreshes the National Broadband Map periodically rather than continuously. We update our pages when new data is published, and we show the vintage of the underlying data so you can judge it for yourself.
What we do not do
- We do not sell your personal details to internet providers.
- We do not run a call center and we will not phone you.
- We do not publish speeds or prices we cannot tie back to a source.
- We do not accept payment to rank one provider above another. Where a provider pays us a commission, we say so. See our affiliate disclosure.
An honest limitation
Reported availability is not the same as a guaranteed connection. Providers self-report to the FCC, and the data is known to overstate coverage in some areas. Treat what you find here as the starting point for a conversation with a provider, not a promise. If a provider tells you they cannot serve your address, they are right and the map is wrong.
Who runs it
WhereFiber is operated by WhereFiber, an independent publisher. We are not owned by, affiliated with, or endorsed by any internet service provider.
