Three checks, in this order, will give you a dependable answer. Start with an area-level lookup to build a shortlist of the companies that operate near you. Then run your exact street address through each of those providers’ own order flows. Finally, cross-check the result against the FCC’s National Broadband Map, an independent record of what each provider has told the federal government about your specific building.
The shortlist tells you who to ask. The provider check tells you who will actually sell to you. The FCC map is what you use when one of those answers looks wrong, and it is wrong often enough that the FCC runs a formal process for correcting it.
Why “in my area” is the wrong unit of measurement
Almost every free availability tool answers a geographic question you did not ask. ZIP codes are postal routing units and counties are administrative boundaries. Networks are not built to either. They are built along streets, from specific cabinets, nodes and towers.
That mismatch is not a rounding error. AT&T’s own fiber page carries the plain disclosure that AT&T Fiber is limited to certain availability areas, which is a fair description of how fiber gets built: block by block, over years. Cable footprints follow decades-old build-out patterns and stop at edges that make no visual sense from the street. Fixed wireless from a mobile carrier is qualified address by address. Satellite is the only category that is close to geographically universal, and it has its own limits.
The FCC works at the right resolution here. Under its Broadband Data Collection, fixed providers do not report the counties or ZIP codes they serve. They report availability location by location, against the individual building points shown on the national map. So the honest translation of any area-level result is this: these are the companies operating around you, and these are the ones worth calling.
Step 1: Build a shortlist from county-level data
Our own Broadband Coverage Lookup is deliberately explicit about what it is. You enter a ZIP code, it matches that ZIP to the county it sits in, and it shows which providers filed service for that county with the FCC, currently from the collection dated December 31, 2025. Each provider card shows the share of homes that company reported reaching in the county, the plan and phone details we have checked by hand, and the date we last checked them. Anything we have not verified ourselves is labeled unverified rather than filled in with a guess.
A county-level result never means service is available at your address. Two houses on the same block can get different answers, and our tool says so on the page.
What this step is genuinely for is a complete list of names. Provider searches surface the companies with marketing budgets. A filings-based list also surfaces electric cooperatives, municipal networks and small wireless providers that may be the best option at a given address and that rarely appear in advertising. If your options look thin, those smaller names are the part of the list worth your attention, and our rural internet guide covers how to approach them.
Step 2: Run your exact street address past each provider
Take your shortlist and check each provider’s own address form. Enter the full street address, including any unit or apartment number, and watch for a residential-versus-business toggle, because choosing the wrong one changes the results you see. Some companies run more than one kind of network behind a single check, so one form can cover fiber and wireless options at once.
What a provider’s check proves, and what it does not
A provider’s own address check and order flow is the practical final step before you buy, because it is the only place a company will actually quote you a plan and an installation date. Even a positive result can occasionally be wrong, or can change once installation is scheduled.
The FCC’s own list of things consumers are allowed to dispute reads like a catalog of those failures. A provider may be willing to connect you but unable to offer an installation date within ten business days. It may quote installation or construction charges well above its standard fee. It may report a technology it will not actually install at your address. It may list maximum speeds that are not actually available for purchase there. A fixed wireless or satellite service may be oversubscribed where you live.
Our advice, and this is advice rather than a rule: when a check says yes, capture the specifics before you agree to anything. Write down the exact plan name, the promised installation date and the quoted installation charge. Those details are what you will need if the order stalls, and they are the evidence the FCC asks for if you end up filing a challenge.
Step 3: Cross-check the FCC National Broadband Map
The map is free, it takes a street address, and it is the closest thing to a neutral second opinion that exists.
What the map actually shows
Enter your address in the Search by Address box. If it is in the FCC’s location database, it appears in capital letters in the suggestion list. Select it and you get a Location Summary listing the providers that report service at that point, the technology each one reports, and the maximum advertised download and upload speeds each says are available for purchase there.
The dots are buildings, not areas. Green means at least one provider reports service, red means none does, and gray marks structures unlikely to buy the kind of service sold to homes and small businesses. Providers file twice a year, with data as of June 30 and December 31, and a Data As-Of Date selector lets you change which snapshot you are viewing. The most recent published snapshot is December 31, 2025.
One quirk is worth knowing. The default view leaves out services below 25 Mbps download, so a slow legacy connection can exist at an address that looks red, and will only appear once you loosen the speed filter.
What the map does not establish
The FCC is direct about the limits, and those matter more than the strengths. The map shows availability, not network performance, affordability or adoption. Advertised speeds are what a provider says you can buy, not what you will measure, and our guide to checking your internet speed covers the difference.
The mobile coverage layer is generated from propagation models, reflects outdoor and in-vehicle use, and does not represent indoor coverage. That makes it a poor proxy for how a home gateway will behave inside your house.
A green dot also does not mean an order will go through this week. It means a provider reported that it could connect that location under the FCC’s definition. And for an apartment or condo building, the point represents the whole building rather than your unit.
What “available” means to the FCC
This definition explains most of the confusion people run into. Service counts as available at a location if the provider has, or previously had, a connection in service there, or if it could start service through a routine installation within ten business days of a request, with no extraordinary charges or delays from extending its network.
Two things follow. A previously served address can still show as served even if nobody there can order today. And “routine installation” is doing a lot of work in that sentence, because a build that needs trenching, new equipment or a non-standard fee is not routine. That gap is where most disappointed buyers end up.
What to do when the provider and the map disagree
If the map says available and the provider says no
You can file an availability challenge from the location’s panel on the map, on the Fixed Broadband tab. You will need your name and email address, the reason code that fits your situation, a description of what happened when you tried to order, and any supporting evidence such as a screenshot of the refusal or notes from the call. For fiber specifically, our guide to why fiber is not available at your address covers the challenge process and how to read a funded build timeline.
Set expectations before you invest the effort. FCC staff screen the submission first, which takes a few days, and they will reject it if it is really a billing or service-quality complaint. If it is accepted, the provider has 60 days to concede or rebut. If it rebuts, you and the provider are expected to work it out directly over the following 60 days. If that fails, the FCC decides within 90 days, and a provider that concedes or loses has 30 days to update its data so the location no longer shows as served.
A challenge is how you correct the public record, and that record feeds federal and state funding decisions about which areas count as unserved. It is not how you get connected next week. If you need service now, treat the challenge as a parallel task and spend your immediate effort on the other names on your shortlist.
One clarification saves wasted filings. If you already have service and it is slower than advertised, that is not an availability challenge. The FCC handles those submissions as consumer complaints.
If a provider serves you but is not on the map
Use the same form and choose Add Missing Provider, then enter the provider’s name and technology. No evidence is required. This does not create a formal challenge. It is recorded as crowdsource data, shared with the provider, and used by the FCC to spot patterns worth investigating.
If the problem is the building point itself, missing or in the wrong place, the fix is a location challenge instead, linked next to the address on the map.
Neither route is dramatic, and both take a few minutes. We think they are worth doing for the same reason we publish our own check dates. The data only improves if the people who can see the errors report them.
The situations that break the simple answer
Apartments, condos and other multi-unit buildings
Multi-unit buildings are the least reliable case for every availability tool, including ours and the FCC’s. The map shows your building as a single location point, so it cannot tell you whether a service reaches your particular unit. Always enter your unit number in a provider’s check, and expect answers that differ from a neighbor’s in the same building.
Building-level arrangements and existing in-unit wiring are not published anywhere we can verify, so the practical move is to ask locally rather than trust a form. Ask the property manager which providers currently have equipment in the building and whether any service is included in the rent, and ask a neighbor with service which provider and plan they actually receive. That is advice, not a documented fact, but it is faster than any other method we know.
Fiber, and the neighbor who has it
A neighbor with fiber is a useful signal that a fiber network is close. It is not evidence that you can order it. Fiber availability is decided address by address, and if connecting your home requires work beyond a routine installation, you are into scheduling and cost questions rather than a simple yes.
If you are in this position, ask the provider directly whether your address is on the current build list and whether any construction is needed, then re-check every few months rather than once a year. Our fiber, cable and DSL explainer covers why the persistence is usually worth it.
5G home internet and fixed wireless
Fixed wireless from a mobile carrier is qualified address by address, and availability depends on network capacity in your area, which is why two nearby addresses can get different answers and why a no can turn into a yes later. T-Mobile’s home internet page frames it that way, asking you to check your address and to check back as coverage expands. The day-to-day trade-offs against a wired connection are covered in our cable versus 5G home internet comparison.
Satellite
Satellite is listed alongside wired technologies on the FCC map wherever providers report it, and in our view it is the fallback worth checking whenever the rest of your shortlist comes back empty. Availability is still not unconditional. Capacity in your area, the hardware offer available where you live and a clear view of the sky all matter, and Starlink states that the speeds it references are maximum available speeds, not guaranteed, and will be slower during times of congestion. Our Starlink review and our HughesNet versus Viasat comparison cover what that means in practice.
Before you order, compare the offer rather than the availability
Once two or more providers will actually sell to your address, availability stops being the question and terms take over. Do not assume the terms follow the technology, and do not assume they are consistent within one company. Comcast’s own support documentation is a clean example: newer Xfinity plans are described as including unlimited data and equipment at no extra cost with no annual contract, while previous plans include a 1.2 TB monthly data allowance. Same provider, different answers, depending on which plan you are on. When you have picked a winner, our guide to switching internet providers without losing service covers the order of operations on switchover day.
So confirm six things on the order screen, in writing: the price during the promotional period and the price after it ends, whether a term commitment and early termination fee apply, whether equipment is included or rented monthly, what installation costs, whether a data allowance applies, and the upload speed rather than just the download figure.
For the mechanics of that comparison we have already written the parts that would otherwise be repeated here: what happens when your intro rate ends, what to check in an internet contract and how data caps work. If the shortlist comes back thin or expensive, see the cheapest categories worth considering, and if you are staying put, how to lower a bill you already have.
The ten-minute version
- Run your ZIP through a county-level lookup and write down every provider name and phone number, including the small ones.
- Check your exact street address, with unit number, on each of those providers’ own sites.
- Look your address up on the FCC National Broadband Map and compare what providers reported against what they just told you.
- If the two disagree, file an availability challenge, or add a missing provider if a company serves you but is not listed.
- Before ordering, get the post-promotional price, contract terms, equipment and installation costs, any data allowance and the upload speed in writing.
How we checked this
Facts in this article were verified on August 18, 2026 against primary sources: the FCC’s Broadband Data Collection pages and the FCC’s BDC help center articles on what the map shows, how to use it, how to submit an availability challenge, what to expect afterward and how to report a missing provider, plus the official AT&T, T-Mobile, Starlink and Xfinity pages linked above. Availability data on the FCC map, and in our own lookup, reflects the collection dated December 31, 2025.
We do not take payment to include or rank providers in this guide, and we do not quote plan prices here, because prices change faster than any article can honestly track. Where our Coverage Lookup shows pricing, each card carries the date we last checked it.
