Current ZIP-level provider data shows a market dominated by wired infrastructure, with Xfinity reported at approximately 99.9% coverage and Sonic fiber at approximately 78.6%. AT&T is also reported at about 62%, while wireless providers create additional address-dependent choices. These percentages describe provider-reported or secondary coverage estimates, not guaranteed service at every residence.
Current 94122 provider data reports Xfinity cable availability at approximately 99.9%. The figure indicates that cable infrastructure reaches nearly the entire ZIP in the underlying dataset, making Xfinity the most consistently documented wired option across 94122. Individual building records can still differ.
Sonic is reported at approximately 78.6% availability in 94122. That is materially different from a small pilot footprint and makes fiber an important part of the local comparison. Sonic's San Francisco network offers fiber service with symmetric speeds where the network reaches the property.
T-Mobile and Verizon are reported as home-internet alternatives in 94122. Their service does not depend on the same neighborhood cable or fiber plant, but eligibility can depend on wireless capacity, signal conditions and the exact service address.
The comparison separates ZIP-level evidence from address-level serviceability. Coverage percentages come from current secondary provider data and should be treated as indicators of the local market, not as live ordering results.

The provider descriptions below focus on the evidence available for 94122 and distinguish ZIP-level provider presence from actual serviceability at a house or multifamily building.
Xfinity is the most broadly reported wired provider in 94122. Current ZIP-level data places its cable availability at approximately 99.9%, making the Xfinity network a defining part of the local broadband infrastructure. The breadth of that footprint means that many 94122 properties can compare cable service against fiber or wireless alternatives, although the ZIP percentage does not guarantee service to every unit.
Sonic is a major fiber alternative in 94122. Current ZIP-level data reports Sonic fiber availability at approximately 78.6%, which makes fiber access an important part of broadband research across the Sunset area. Sonic's current residential network is fiber-to-the-home, with symmetric service on applicable plans.
AT&T is another significant broadband network to check in 94122. Current ZIP-level provider data reports approximately 62% AT&T availability, but that figure combines AT&T service categories. It should not be read as 62% fiber coverage. AT&T's San Francisco information states that Fiber is available in many neighborhoods and that the actual service offering depends on the address.
T-Mobile Home Internet provides a wireless alternative to the wired networks in 94122. Instead of requiring a cable or fiber line into the building, the service uses T-Mobile's wireless network. This can make it relevant to properties where a wired option is unavailable, unsuitable or otherwise constrained, but eligibility depends on address-level capacity.
Verizon 5G Home Internet is another wireless option reported in 94122. Its home-internet footprint is much smaller in the ZIP-level provider data than the Xfinity cable network. Verizon's wireless infrastructure is separate from the wired networks, so a property without a qualifying fiber option can still have a different result through fixed wireless.
94122 has more fixed-wireless providers than a basic comparison of the largest national ISPs would suggest. Current ZIP-level data reports XNET WiFi at approximately 65.5%, Etheric Networks at about 41.3% and Unwired at approximately 99.9%. These figures should be interpreted cautiously because fixed-wireless service can depend on network design and property-specific conditions.
Speed requirements depend on household activity, but the network technology matters as much as the advertised download number. In 94122, the relevant comparison can be between Xfinity cable and Sonic or AT&T fiber, with fixed wireless providing another option at qualifying addresses.
Appropriate for ordinary browsing, video calls, HD streaming and smaller households when the connection is stable.
Useful for households with several simultaneous users, multiple streaming devices, larger downloads and regular work-from-home use.
Relevant for larger households, frequent large downloads, many simultaneously active devices or homes using high-capacity wired connections.
Relevant only where Sonic or AT&T fiber reaches the property and the home's router, Ethernet or Wi-Fi equipment can use the additional capacity.
The ZIP has several distinct broadband technologies. Their coverage patterns are not interchangeable: the nearly ZIP-wide Xfinity cable footprint, the large reported Sonic fiber footprint and the smaller address-dependent wireless networks represent different infrastructure models.
Sonic is the most broadly reported dedicated fiber network in current 94122 provider data, while AT&T also has fiber in parts of San Francisco. Fiber should be checked first at an address where upload capacity is important because availability is property-specific.
Xfinity is the dominant reported wired technology in 94122. Current ZIP-level data places its cable footprint at approximately 99.9%, making cable the most broadly documented fixed network in the ZIP.
T-Mobile and Verizon provide wireless home-internet alternatives, while XNET, Etheric and Unwired add additional fixed-wireless networks. Eligibility depends on the individual location and network conditions.
Satellite services such as Starlink and HughesNet are geographically available across 94122. They do not rely on the neighborhood cable or fiber plant and therefore represent a separate infrastructure option.
ZIP 94122 covers the Inner and Outer Sunset portion of western San Francisco. The geography includes dense residential streets, commercial corridors and a mix of housing types. Those characteristics matter because provider networks are deployed to individual streets, buildings and serviceable locations rather than to ZIP codes as a single unit.
San Francisco's ZIP-code mapping identifies 94122 with the Inner and Outer Sunset. This is important for broadband research because the ZIP is a large western residential area rather than one small neighborhood. Provider coverage should therefore be evaluated against the actual street and property.
Current 94122 provider data reports Xfinity at approximately 99.9% availability. This makes cable the most consistently documented wired broadband technology across the ZIP and provides a useful baseline when evaluating whether a particular property has a fiber alternative.
Sonic is reported at approximately 78.6% availability in 94122. That makes fiber a significant part of the ZIP's broadband market. A resident who sees only a general provider list may miss the more important distinction: the relevant question is whether Sonic reaches the specific building or unit.
Current ZIP-level data reports AT&T service at approximately 62% in 94122, while AT&T separately confirms that fiber is available in many San Francisco neighborhoods. Because the ZIP figure combines AT&T technologies, it should not be interpreted as a direct measure of fiber coverage. Address-level verification is particularly important for AT&T.
The Sunset area contains established residential blocks with single-family homes, apartments and mixed-use properties along commercial streets. A network can reach a neighborhood without every building having the same internal wiring, unit configuration or installation path. Multifamily residents should therefore verify the exact building and unit when possible.
94122 includes established commercial corridors such as Irving Street, Noriega Street and Taraval-area streets. The ZIP's residential broadband picture should not be inferred from a commercial address or vice versa. Business and residential service can use different products, eligibility rules and network arrangements.
These findings focus on what the available ZIP-level evidence actually establishes. Coverage percentages are useful for understanding the market but do not replace a provider's address-level service check.
| Finding | Evidence | What it means for a 94122 address |
|---|---|---|
| Xfinity cable | Current ZIP-level provider data reports approximately 99.9% availability. | Xfinity is the most broadly reported wired network in the ZIP, but building-level verification is still appropriate. |
| Sonic fiber | Current provider data reports approximately 78.6% availability. | Fiber is a substantial part of the 94122 market rather than a marginal technology option. |
| AT&T | Current provider data reports approximately 62% AT&T availability, while AT&T confirms fiber availability in parts of San Francisco. | AT&T should be checked independently because the ZIP percentage combines multiple AT&T service categories. |
| T-Mobile Home Internet | Current provider data identifies T-Mobile 5G home internet in the 94122 market. | Wireless eligibility may differ between nearby properties because network capacity and signal conditions are location-specific. |
| Verizon 5G Home | Current provider data identifies Verizon 5G home internet with a smaller reported footprint. | Verizon is a secondary wireless option to investigate rather than assuming it is available at every address. |
| Fixed wireless | XNET, Etheric and Unwired also appear in current 94122 provider data. | A simple list of the largest national ISPs understates the number of fixed-wireless networks reported in the ZIP. |
| Fiber versus cable | The ZIP combines a nearly ZIP-wide reported cable footprint with a large reported Sonic fiber footprint. | The central address-level comparison for many properties is not whether broadband exists, but which wired technology is actually available. |
ZIP 94122 spans the Inner and Outer Sunset portion of San Francisco. Neighborhood geography helps explain why a ZIP-wide provider list can contain more choices than a particular property can actually order.
A ZIP-code provider list is a starting point. The FCC's broadband mapping system uses location-level records, while providers such as AT&T, Sonic and Astound require address-level checks for current serviceability.
Broadband networks cross ZIP boundaries. Nearby ZIP codes can therefore provide useful context, but their provider percentages should not be substituted for 94122 address-level information.
This page treats ZIP-level broadband coverage as market evidence rather than as a substitute for address-level serviceability.
Different broadband directories can produce different ZIP-level percentages because they use different data vintages, provider reporting and methodologies. This page does not convert those differences into a false precise figure.
The FCC explains that its National Broadband Map displays fixed broadband availability at individual locations and reports the technologies and maximum advertised speeds submitted through the Broadband Data Collection. That location-level approach is why a ZIP-wide percentage should not be interpreted as a guarantee for every address.
These answers summarize the ZIP-level evidence and identify where address-level verification is still required.
