Check Internet & Fiber Availability by Address | AT&T

Enter your full street address, including your unit number if you have one, in the address checker on this page to see which plans and speeds are available at your location. Results are address-specific, not city or ZIP code level, and they show every option available there: AT&T Fiber, AT&T Internet Air or both. Plans can differ even between neighboring addresses. This check also tells you whether your address is eligible, or serviceable, for each service. Once you see your options, compare internet plans and speeds.

AT&T Fiber delivers internet over a physical fiber-optic cable run to your home, with speeds up to 5 GIG. AT&T Internet Air delivers internet wirelessly over the AT&T 5G network through the All-Fi Hub, with self-setup and typical download speeds of 90-300 Mbps. Fiber supports the highest speeds, and Internet Air needs no cable installation. Which option you can get depends on your address, so use the checker above to see which service, or both.

Enter your address in the checker to find out if Fiber is available at yours. If it isn't, consider AT&T Internet Air, our wireless home internet over the AT&T 5G network.

AT&T Fiber availability is determined address by address, based on where fiber-optic infrastructure has been built, not by neighborhood or ZIP code. Buildout happens incrementally, so one street or building may be served before the next, even in the same city. Timing depends on permitting, access to property and local conditions. Get notified when fiber reaches your address and view the AT&T Fiber coverage map.

Several factors affect which AT&T services, such as AT&T Fiber and AT&T Internet Air, are available at your home, including your location, local infrastructure, the type of wiring in your neighborhood, local construction and network upgrades. Internet Air eligibility also depends on 5G signal strength at your address. Serviceability and eligibility are checked per address, so the best way to see what is available is to enter your address in the checker above.
