ISP Coverage Checker

Enter your 5-digit zip code in the search box above. Our tool cross-references your location against coverage data from every major US internet provider, including Xfinity, Spectrum, AT&T, Verizon Fios, Cox, and T-Mobile 5G Home Internet. For address-level precision, you can also check the FCC National Broadband Map.

Fiber optic internet is the fastest and most reliable type, offering symmetrical upload and download speeds up to 8 Gbps with providers like AT&T Fiber, Verizon Fios, and Google Fiber. Cable internet (Xfinity, Spectrum) typically offers speeds up to 1-2 Gbps download but slower uploads. 5G fixed wireless is emerging as a strong third option, while DSL and satellite are slower alternatives for rural areas.

Internet providers build physical infrastructure (fiber lines, cable networks, cell towers) that serves specific geographic areas. This is expensive, so each provider covers different regions. Urban areas typically have 4-8 providers competing for customers, while rural areas may only have 1-2 options. Federal programs like the BEAD initiative are working to expand broadband access to underserved areas.

For basic browsing and email, 25 Mbps is sufficient. Streaming HD video needs 25-50 Mbps per device. Remote work with video calls requires 50-100 Mbps. Gaming households with multiple users should target 200-500 Mbps. If you have 5+ devices streaming simultaneously, 500 Mbps to 1 Gbps gives the best experience. Fiber connections are ideal for households that need strong upload speeds for video calls and cloud backups.

Fiber is generally superior in every measurable way: faster speeds (up to 8 Gbps vs 1-2 Gbps), symmetrical upload/download, lower latency (important for gaming and video calls), and better reliability during peak hours. Cable internet uses shared bandwidth, so speeds can slow down when neighbors are online. The main advantage of cable is wider availability, as fiber infrastructure is still being built out across much of the country.

5G home internet uses cellular towers instead of wired connections to deliver broadband. T-Mobile and Verizon offer fixed wireless plans starting around $25-50 per month with speeds of 100-300 Mbps. It is a solid option if fiber or cable are unavailable, and the no-contract, no-installation model is convenient. However, speeds depend on your distance from the tower and can be less consistent than wired connections during peak hours.
