Start with your street address, not your zip code

The only way to know which internet providers actually serve your home is to enter your street address into their service maps. Zip codes cover too much ground — one zip code can have cable service on one block and only DSL on another, or fiber on a new street while older blocks have nothing but satellite. Typing your address into each provider's website takes five minutes per company and gives you the real answer.

You will need your full street address including the apartment or unit number if you have one. If you are renting, the address on your lease is what matters. If you are buying, use the address from your purchase agreement or the property listing.

Key Takeaways

  • Enter your full street address into each provider's service map on their website — zip codes are too broad to tell you what actually reaches your home.
  • The major providers in most areas are cable companies (Comcast, Charter, Cox), telephone companies (AT&T, Verizon, CenturyLink), and fiber startups, plus satellite as a backup option.
  • Your city or county may have a broadband map showing which providers serve which streets, updated more recently than some company websites.
  • Speeds and prices vary widely even between addresses on the same street, so check each provider's current offers for your specific location.
  • If only one or two providers serve you, contact them directly about current promotions — they often have deals not listed on their main website.

The four types of providers and where they operate

Cable companies (Comcast Xfinity, Charter Spectrum, Cox Communications) operate in specific regions and do not overlap much. Comcast covers the Northeast, upper Midwest, and parts of the West Coast. Charter Spectrum covers much of the South, Midwest, and West. Cox operates in Arizona, California, Louisiana, Nevada, and Oklahoma. If you live in one of their service areas, they usually offer the fastest speeds available to residential customers, typically 100 Mbps to 1 Gbps depending on your neighborhood.

Telephone companies (AT&T, Verizon, CenturyLink, Frontier) offer DSL or fiber over phone lines they already own. AT&T and Verizon cover large regions but do not serve everywhere — check their maps. CenturyLink and Frontier serve rural and smaller cities. DSL speeds max out around 25 Mbps in most places, though fiber from these companies can reach 1 Gbps where available.

Fiber startups (Google Fiber, Starry, Ting, local municipal broadband) are expanding in specific cities and neighborhoods. These are newer and faster than cable or DSL where they exist, often offering 1 Gbps or higher. They do not serve most of the country yet, but if one operates in your city, check whether your street is wired.

Satellite providers (Starlink, Viasat, HughesNet) reach anywhere with a clear view of the sky. Speeds are slower and data caps are tighter than wired options, but satellite is often the only choice in rural areas. Starlink has improved speed and latency enough that some people choose it over DSL, though it still lags cable and fiber.

How to check each provider's service map

Visit the provider's website and look for "Check availability", "Service map", or "See if we serve your area" — the button is usually on the home page. Type in your street address and apartment number if you have one. The map will tell you whether that address is serviceable, what speeds are available, and sometimes what the current price is.

Write down the results for each provider: the speeds offered, the price for the first year if shown, and any equipment fees. Speeds matter because they determine what you can actually do — 25 Mbps works for email and web browsing but struggles with video calls or streaming. 100 Mbps handles most household uses. 500 Mbps or higher is overkill for most people unless you have many devices streaming at once or work from home with large file uploads.

If a provider's website says your address is not serviceable, that usually means they do not serve it. Calling to ask rarely changes the answer, because service maps are based on where the company has actually built infrastructure. The exception is if you are at the edge of their service area — sometimes a technician can reach you even if the automated map says no, but expect to pay an installation fee.

Check your city or county broadband map

Many cities and counties now publish broadband maps showing which providers serve which streets. These are often more up-to-date than company websites because they are updated when new fiber is installed. Search "[your city] broadband map" or "[your county] broadband map" to see if yours exists.

The Federal Communications Commission also maintains a broadband map at broadbandmap.fcc.gov. You can enter your address and see what providers the FCC has on record for your area. This map is less detailed than local ones but useful as a cross-check if a provider's website seems wrong.

What to do if only one or two providers serve you

If your address has only one option, you have no choice to make — sign up with that provider. If you have two options, compare their speeds and prices on their websites for your specific address, then pick the faster or cheaper one depending on what matters to you.

Before you sign up, call the provider directly instead of ordering online. Representatives often have access to promotions not shown on the website, especially if you are a new customer in an area with limited competition. Ask what the price is after the promotional period ends, because many introductory rates jump significantly in year two. Ask whether there is a contract and what the early termination fee is if you need to cancel.

What to do if you have three or more options

List the speeds and prices for each provider at your address. Ignore advertised speeds — use the speeds the provider shows for your specific street address on their service map, because speeds vary by neighborhood. Compare the first-year price and the price after the promotion ends. Check whether each provider charges for installation, a modem, or a router.

If two providers offer similar speeds and prices, pick based on customer service reputation. Check reviews on the Better Business Bureau website or Google reviews for each company in your area — satisfaction varies by region because service quality depends on local infrastructure and staffing. Ask friends and neighbors which provider they use and whether they have had problems.

Speed matters more than price if you are choosing between very different options — paying $10 more per month for 300 Mbps instead of 25 Mbps is usually worth it. Price matters more if the speeds are similar, like choosing between 100 Mbps and 200 Mbps from different companies.

Frequently Asked Questions

Why does the provider's website say they serve my zip code but not my street address?

Zip codes contain multiple neighborhoods and sometimes multiple cities. A provider might serve 80% of a zip code but not your specific block. This is common in mixed urban and rural areas. The street address check is always the accurate one.

Can I get a provider to expand service to my address?

Expanding service requires the company to run cable or fiber to your street, which costs tens of thousands of dollars. Most companies will not do this unless a neighborhood petition shows enough demand to make it profitable. Contact your city council or county commissioner to ask whether they have broadband expansion grants or programs that might fund it.

What if the provider's map says they serve me but I cannot get a signal?

Call the provider's technical support and describe the problem. If it is a cable or fiber connection, a technician may need to visit to check the line. If it is DSL or satellite, the issue might be distance from the hub or obstruction. The provider can tell you whether the problem is fixable or whether service is not actually available at your address despite what the map says.

Do I have to use the provider's modem and router?

Most providers require you to use their modem for the internet connection itself, though some allow you to buy your own compatible modem and save the monthly rental fee. You can almost always use your own router connected to their modem. Ask the provider which modems are compatible with your service before you buy one.

What if no provider serves my address?

Satellite is your option. Starlink has the best speeds and lowest latency of the satellite providers. Viasat and HughesNet are alternatives if Starlink is not available or has a waiting list in your area. All satellite services require a clear view of the southern sky and have data caps, but speeds have improved enough that satellite is usable for most tasks.
