About WhereFiber
Last updated: August 12, 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- We do not publish speeds or prices we cannot tie back to a source.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.
What “fiber” means here is narrow, and worth knowing. The FCC's own label for the technology code we publish as fiber is Fiber to the Premises. There is no code for fiber to the cabinet or to the node; service delivered that way is meant to be filed as copper. So a location shown as fiber here, where the fiber in fact stops at a cabinet down the road, is not a boundary case or a matter of interpretation. It is a filing that does not match the label, and it is exactly the sort of thing a challenge to the FCC map exists for.
Who runs it, and from where
WhereFiber is written and run by Ferenc Horvath, working alone, from Sweden. There is no team, no office in the United States and no outside investor.
It is independent of the industry it covers. No internet provider owns any part of it, funds it, reviews it before publication, or has ever paid for placement. Where a provider pays a commission on a referral, that is disclosed on the page it appears on and in the affiliate disclosure.
Being outside the United States is a fair thing to want to know, so it is stated plainly rather than left to be discovered. It does not change what the figures are worth, and that is deliberate: everything published here is computed from the FCC's own public filing, the method is written out on each research page, and the numbers are arranged so that they can be checked against each other and against the federal source. Nothing here rests on trusting the author. If any of it cannot be reproduced from the filing, that is a defect and worth reporting.
