San Francisco ZIP 94105

94105 Internet Providers

Broadband in 94105 reflects the ZIP's unusually dense downtown housing and mixed-use development. Current ZIP-level sources identify AT&T, Xfinity, Astound, Verizon, T-Mobile and several fixed-wireless providers, while Sonic and building-oriented services such as GFiber Webpass add additional connectivity options. The important distinction in 94105 is that network availability and building availability are not the same thing.

● ZIP-level broadband data can identify providers operating in the 94105 market, but high-rise, condominium and apartment properties may have different providers or internal wiring arrangements. Final serviceability should be checked for the exact building and unit.

What the 94105 broadband evidence shows

94105 is different from many San Francisco ZIP codes because its broadband market is closely tied to dense downtown and waterfront development. Current ZIP-level sources show several wired and wireless providers, but the reported coverage percentages vary substantially between datasets. That makes the identity of the network reaching a particular building more useful than a single ZIP-wide percentage.

Fiber

Fiber is a major part of the 94105 comparison

AT&T is reported in current 94105 provider data, while Sonic operates a 10-gigabit fiber network in San Francisco. Property-level evidence also identifies Sonic service in 94105. In a dense downtown ZIP, however, the relevant question is whether the building is connected to a given fiber network rather than whether the network exists somewhere in 94105.

Cable

Xfinity remains an important wired network

Xfinity has documented 94105 service, including an Xfinity community location at 500 Folsom Street. A recent FCC-derived cable dataset reports Xfinity cable at about 90.8% of the ZIP, while a newer September 2026 provider dataset reports a lower overall Xfinity availability figure. The discrepancy is retained rather than presented as one exact coverage number.

Building networks

High-rise service can produce different choices at neighboring addresses

94105 includes Rincon Hill, South Beach, Financial District South and the Embarcadero, with substantial apartment, condominium and mixed-use development. GFiber Webpass and other fixed-wireless providers have smaller reported footprints, and property-level records show that provider combinations can differ between individual buildings.

94105 provider comparison

The figures below are intentionally labeled by source type. They should not be merged into one coverage ranking because the underlying datasets use different reporting periods and methodologies. The FCC's broadband mapping system is based on provider-submitted location-level availability, while third-party ZIP pages may aggregate those records differently.

Provider Technology 94105 evidence Advertised maximum What to verify
AT&T
Current ZIP presence 		Fiber / IPBB / fixed wireless A September 2026 ZIP provider dataset reports approximately 73.9% AT&T availability in 94105. The source combines AT&T technologies, so the figure does not establish that 73.9% of the ZIP has AT&T Fiber. Up to 5 Gbps on current fiber offerings where available Whether the exact building receives AT&T Fiber or another AT&T service
Xfinity
Documented wired presence 		Cable Xfinity has a documented 94105 location at 500 Folsom Street. A November 2025 FCC-derived cable dataset reports approximately 90.8% cable coverage, while a September 2026 ZIP provider source reports approximately 52.9% overall Xfinity availability. Up to 2 Gbps in current reported offerings Exact building, plan tier, upload speed, equipment and pricing
Sonic
San Francisco fiber 		Fiber Sonic operates a wholly owned 10-gigabit fiber network in San Francisco. Property-level 94105 evidence also identifies Sonic service, although the sources reviewed do not provide a defensible current ZIP-wide Sonic percentage. Up to 10 Gbps Exact building, address eligibility and current plan
Astound Broadband
Partial wired footprint 		Cable Current September 2026 ZIP data reports approximately 33.4% Astound availability. A separate FCC-derived cable dataset reports approximately 15.15% cable coverage in 94105. Up to 1.5 Gbps in current reported offerings Whether the exact building is connected to Astound's network
Verizon 5G Home Internet
Current wireless presence 		5G fixed wireless A September 2026 ZIP provider dataset reports Verizon availability at 100% in 94105. This is a coverage indicator rather than a live order result and does not establish identical indoor performance throughout every high-rise or unit. Up to 300 Mbps in the cited current ZIP dataset Exact address, plan eligibility, signal and capacity
T-Mobile Home Internet
5G / fixed wireless 		5G fixed wireless Current San Francisco provider data identifies T-Mobile 5G Home Internet, while 94105 provider data identifies T-Mobile wireless service in the ZIP. Fixed-wireless eligibility can vary by address and available network capacity. Up to about 498 Mbps in current San Francisco reporting Address eligibility, capacity, signal and current plan
Unwired
Fixed wireless 		Fixed wireless A September 2026 ZIP provider source reports approximately 99.7% Unwired availability in 94105. The figure should be treated as a dataset coverage indicator rather than a guarantee for every unit. Up to 300 Mbps in current ZIP reporting Exact property, equipment and wireless conditions
XNET WiFi
Fixed wireless 		Fixed wireless Current September 2026 ZIP data reports approximately 53.3% XNET WiFi availability in 94105. This represents another local wireless option alongside the major national carriers. Up to 2 Gbps in current ZIP reporting Address eligibility and current network footprint
Etheric Networks
Fixed wireless 		Fixed wireless A September 2026 ZIP provider dataset reports approximately 48.5% Etheric availability in 94105. Up to 250 Mbps in current ZIP reporting Exact address and network conditions
GFiber Webpass
Building-dependent 		Building-oriented service Current ZIP provider data reports approximately 11.7% availability for GFiber Webpass. A 94105 property record has also documented Webpass service, illustrating why building-specific verification can reveal options not obvious from a broad ZIP list. Up to 1 Gbps in current reporting Whether the specific building is connected
Satellite providers
Geographic option 		Satellite Satellite providers such as Starlink and HughesNet are geographically available in the ZIP and do not rely on the same neighborhood wired plant as cable and fiber. Provider and plan dependent Equipment location, sky view, latency and plan terms
ZIP-level interpretation: 94105 has evidence of multiple competing wired and wireless networks, but the available datasets produce materially different percentages. The September 2026 provider source reports AT&T at about 73.9%, Xfinity at 52.9%, Astound at 33.4%, Verizon at 100%, Unwired at 99.7%, XNET at 53.3%, Etheric at 48.5% and GFiber Webpass at 11.7%. A separate FCC-derived cable dataset reports Xfinity cable at 90.8% and Astound cable at 15.15%. These differences are retained as part of the evidence rather than presenting one number as an exact current ZIP-wide truth.

Internet providers serving the 94105 market

The provider descriptions below separate direct local evidence from citywide provider information. Where a source does not establish a current ZIP-wide percentage, the page does not invent one.

AT&T

Fiber / IPBB Current ZIP presence Up to 5 Gbps fiber

AT&T is an important part of the 94105 broadband comparison. A current September 2026 ZIP provider dataset reports approximately 73.9% AT&T availability. That figure combines AT&T technologies, however, so it should not be interpreted as 73.9% fiber coverage. AT&T's fiber network is the relevant service to investigate where high-capacity symmetric connectivity is available.

  • AT&T's current fiber offering can reach multi-gigabit speeds where available.
  • ZIP-level AT&T figures can include more than one access technology.
  • The exact building determines whether fiber is offered.
  • High-rise service should be verified at the building and unit level.
Local evidence: The September 2026 94105 provider dataset reports approximately 73.9% AT&T availability. The figure is treated as an overall AT&T coverage indicator rather than as a fiber-only percentage.

Xfinity

Cable Documented 94105 service Up to 2 Gbps reported

Xfinity has direct evidence of service inside 94105, including its 500 Folsom Street community location. A recent FCC-derived cable dataset reports approximately 90.8% Xfinity cable coverage in the ZIP, while a newer September 2026 provider dataset reports approximately 52.9% overall Xfinity availability. The difference is significant enough that neither figure should be presented as an exact current household coverage percentage.

  • Xfinity is a documented wired provider inside the ZIP.
  • Current reported residential tiers can reach multi-gigabit download speeds.
  • Cable upload performance should be compared directly with fiber.
  • Building wiring and property-level serviceability remain relevant.
Local evidence: Xfinity identifies 500 Folsom Street, San Francisco, CA 94105 as an Xfinity location. The current ZIP evidence is supplemented by an FCC-derived cable dataset reporting 90.8% Xfinity cable coverage.

Sonic

Fiber San Francisco network Up to 10 Gbps

Sonic is an important fiber provider to investigate in 94105. Sonic's current San Francisco information describes a wholly owned 10-gigabit fiber network, and property-level evidence has documented Sonic service at a 94105 address. The sources reviewed do not provide a sufficiently consistent current ZIP-wide percentage to assign Sonic a precise 94105 coverage figure.

  • Sonic uses fiber rather than the traditional cable architecture.
  • Current San Francisco residential service can reach 10 Gbps where available.
  • Fiber service can provide symmetric upload and download capacity.
  • Building-level qualification is more useful than a citywide percentage.
Local evidence: Sonic's current San Francisco residential information describes its 10-Gigabit fiber network. A 94105 property record also documents Sonic service, but this page does not convert that property evidence into a ZIP-wide coverage percentage.

Astound Broadband

Cable Partial 94105 footprint Up to 1.5 Gbps reported

Astound provides another wired option in 94105, but its reported footprint is materially smaller than the broadest cable estimates for Xfinity. A current September 2026 ZIP source reports approximately 33.4% Astound availability, while an FCC-derived cable dataset reports approximately 15.15% cable coverage. The differing figures reinforce the need to check the building directly.

  • Astound is reported as a cable provider in 94105.
  • Current reported download capacity reaches approximately 1.5 Gbps.
  • Its network does not appear uniformly throughout the ZIP.
  • Astound's own address checker is the appropriate final verification step.
Evidence standard: The two ZIP datasets are presented side by side rather than selecting one percentage as the definitive current Astound footprint.

Verizon 5G Home Internet

5G fixed wireless 94105 ZIP presence Address dependent

Verizon is notable in the 94105 data because the current September 2026 ZIP provider source reports approximately 100% availability. That does not mean every apartment has the same indoor wireless conditions or that every unit will receive the same plan. In a high-rise-heavy ZIP, building construction, window placement, signal and network capacity can affect the practical result.

  • Service uses Verizon's wireless network rather than neighborhood cable plant.
  • ZIP-level availability should not be confused with guaranteed indoor performance.
  • Signal and capacity can vary by property.
  • Verizon's current address checker remains the final service test.
Local evidence: The September 2026 94105 provider dataset reports approximately 100% Verizon availability. This is treated as a coverage indicator, not as a prediction of signal quality at every unit.

T-Mobile Home Internet

5G fixed wireless 94105 market presence Capacity dependent

T-Mobile provides a wireless alternative to the wired networks in 94105. Current San Francisco provider data identifies T-Mobile 5G Home Internet, and current ZIP-level provider information includes T-Mobile among the local wireless choices. Unlike cable or fiber, fixed-wireless eligibility can depend on network capacity at the serving site as well as the address.

  • No dedicated cable or fiber drop to the home is required.
  • Wireless conditions can vary by building and location.
  • High-rise construction can affect indoor wireless performance.
  • The current address check is required before treating the service as available.
Local evidence: Current San Francisco and 94105 provider data identify T-Mobile 5G Home Internet in the market. The source data is treated as an indicator of market presence rather than a building-level guarantee.

Unwired

Fixed wireless High reported ZIP coverage Up to 300 Mbps reported

Unwired is a smaller fixed-wireless provider that appears prominently in current 94105 coverage data. A September 2026 ZIP provider dataset reports approximately 99.7% availability. Because the figure comes from a coverage dataset rather than a live order system, it should be used to identify the provider for further investigation rather than as a guarantee for every address.

  • Fixed wireless uses a different access architecture from cable and fiber.
  • Current ZIP data reports up to about 300 Mbps.
  • Exact installation conditions can determine eligibility.
  • Building and equipment requirements should be verified directly.
Local evidence: The September 2026 94105 provider source reports approximately 99.7% Unwired availability.

GFiber Webpass

Building-oriented service Limited 94105 footprint Up to 1 Gbps reported

GFiber Webpass deserves separate treatment in 94105 because downtown building density makes building-specific broadband networks more relevant than they are in many suburban ZIP codes. Current ZIP-level data reports approximately 11.7% availability, while a property record at 199 New Montgomery Street documents Webpass service. This is useful evidence of local presence but not evidence that neighboring buildings qualify.

  • Webpass service can be strongly dependent on building connectivity.
  • Current ZIP data reports a limited 94105 footprint.
  • Existing building wiring and provider agreements can matter.
  • The building address is more informative than the ZIP percentage.
Local evidence: Current ZIP data reports approximately 11.7% GFiber Webpass availability, while a 94105 property listing documents Webpass at 199 New Montgomery Street. The two pieces of evidence support local presence without establishing ZIP-wide availability.

94105 internet speed guide

Speed requirements in 94105 depend partly on household activity and partly on the network serving the building. The ZIP has enough fiber, cable and fixed-wireless competition that advertised download speed should not be the only comparison.

100–300

Mbps

A reasonable range for ordinary browsing, video calls, streaming and smaller households when the connection is stable.

500 Mbps

Mbps

Useful for households with multiple simultaneous users, frequent streaming and heavier downloads.

1–2 Gbps

High-capacity plans

Relevant for larger households, heavy transfers and homes with many simultaneously active devices, provided the building network supports it.

5–10 Gbps

Multi-gig fiber

Available only where a qualifying fiber network such as Sonic or AT&T reaches the property and the home's networking equipment can use the additional capacity.

94105-specific comparison: A high-rise resident should not assume that a 10 Gbps fiber plan is automatically usable throughout a building. The connection between the provider network, building equipment, unit wiring and the customer's router can affect the service actually experienced. Compare upload speed, latency, equipment and internal wiring as well as the advertised download tier.

Connection types in 94105

94105 has an unusually mixed urban broadband environment. Fiber and cable networks coexist with 5G and fixed wireless, while some downtown buildings have provider-specific connectivity that does not map neatly onto the ZIP boundary.

Fiber

AT&T and Sonic are important fiber networks to investigate in 94105. Sonic describes a 10-gigabit San Francisco fiber network, while current ZIP data identifies AT&T service. Fiber eligibility should be verified against the building rather than inferred from citywide coverage.

Cable

Xfinity and Astound are the two cable providers appearing in current 94105 evidence. Xfinity has direct service evidence at 500 Folsom Street, while FCC-derived ZIP data shows Astound with a smaller cable footprint.

5G / fixed wireless

Verizon and T-Mobile provide wireless home-internet alternatives, while Unwired, XNET and Etheric add smaller fixed-wireless networks. Their reported coverage can be broad even though exact eligibility and indoor performance still depend on the property.

Building-oriented networks

GFiber Webpass is particularly relevant to dense downtown housing. Current ZIP data reports a smaller footprint, but individual building records can reveal Webpass service where a broad ZIP list might not make the option obvious.

What is different about broadband in 94105?

San Francisco's official ZIP mapping places 94105 across Financial District South, the Embarcadero and Rincon Hill. The area's development pattern is substantially different from lower-density residential ZIPs elsewhere in the city, which changes how broadband availability should be interpreted.

1

94105 is centered on dense downtown and waterfront development

San Francisco's ZIP-code mapping identifies 94105 with Financial District South, the Embarcadero and Rincon Hill. The ZIP therefore contains a high concentration of commercial, residential and mixed-use properties rather than a uniform low-rise residential neighborhood.

2

Rincon Hill's development history matters for broadband research

San Francisco's Rincon Hill Area Plan describes the area as a twelve-block mixed-use neighborhood undergoing transformation from older industrial and parking-lot uses toward substantial residential development. Newer high-rise construction can have different communications infrastructure from older buildings nearby.

3

Building-level competition can be more important than ZIP-level competition

Current 94105 evidence includes Xfinity, AT&T, Astound, Verizon, T-Mobile and smaller fixed-wireless providers. Yet a provider list does not establish that all of those networks enter the same building. In a ZIP dominated by apartment and condominium properties, the building's connected networks can materially narrow the actual choices.

4

Webpass illustrates why property-level research is useful

Current ZIP-level data reports GFiber Webpass at approximately 11.7% availability, while a 94105 property record at 199 New Montgomery Street identifies Webpass service at that building. This is a useful example of how a relatively small ZIP footprint can still matter to a specific building without implying neighborhood-wide availability.

5

Coverage datasets disagree enough that source date and methodology matter

A current September 2026 provider source reports approximately 52.9% overall Xfinity availability in 94105, while a November 2025 FCC-derived cable dataset reports approximately 90.8% Xfinity cable coverage. Astound shows a similar methodological difference, with about 33.4% in the newer provider source and 15.15% in the older FCC-derived cable dataset. These numbers should not be combined or treated as a live building-level measurement.

94105 local broadband findings

The findings below focus on what the current evidence establishes about the ZIP rather than turning provider coverage percentages into claims about every address.

Finding Evidence What it means for a 94105 address
AT&T September 2026 ZIP data reports approximately 73.9% AT&T availability AT&T is a significant ZIP-level option, but the figure combines technologies and does not establish fiber coverage.
Xfinity cable Direct 94105 service evidence plus 90.8% cable coverage in a November 2025 FCC-derived dataset Xfinity is a documented wired option, but the exact building should still be checked.
Sonic fiber Sonic describes a San Francisco 10-Gigabit fiber network; 94105 property evidence identifies Sonic service Sonic should be checked independently where fiber is important, but no unsupported ZIP-wide percentage is assigned here.
Astound Broadband September 2026 ZIP data reports approximately 33.4%; FCC-derived cable data reports approximately 15.15% Astound is a real secondary wired option, but the network does not cover the entire ZIP.
Verizon 5G September 2026 ZIP provider data reports approximately 100% availability Verizon should be checked at the exact address, particularly in high-rise buildings where indoor wireless conditions can differ.
Unwired September 2026 ZIP provider data reports approximately 99.7% availability The provider is a significant fixed-wireless entry in the ZIP dataset and warrants an address-level check.
GFiber Webpass September 2026 ZIP data reports approximately 11.7%; 94105 property evidence documents service at 199 New Montgomery Street Building-specific networks can matter even when their ZIP-wide footprint is relatively small.

Neighborhoods and development patterns inside 94105

These areas are geographic reference points for understanding the ZIP. They should not be interpreted as provider service boundaries because broadband networks follow buildings, utility routes and provider construction rather than postal geography.

Financial District South The northern and central portion of 94105 includes dense commercial, residential and mixed-use development. Broadband choices can depend heavily on which networks have been brought into each building.
Embarcadero Waterfront development within the 94105 geography includes large commercial and residential properties. Building-level serviceability is more precise than applying one ZIP-wide provider percentage.
Rincon Hill A dense mixed-use neighborhood where substantial residential development has changed the area's building stock. Newer high-rise properties may have different internal telecommunications infrastructure from older buildings nearby.
South Beach edge The southern portion of the 94105 area connects closely with South Beach and nearby Mission Bay development. Neighboring ZIPs can therefore have different provider records even where streets and buildings are close.
Transbay / Folsom corridor Dense residential and commercial development around Folsom Street and the Transbay area creates a high concentration of multi-unit properties. Internet service should be verified at the building rather than inferred from a nearby address.
Mixed-use high-rise buildings Many 94105 properties combine residential units with commercial space. Provider availability at the street or building entrance does not automatically establish serviceability for every residential unit.
Why this matters: 94105 is unusually building-dependent. A ZIP-level database can correctly identify several providers as serving the market while a particular condominium or apartment building has only a subset of those networks physically available. This is why address-level and building-level verification should take precedence over a simple provider count.

How to verify internet service at a 94105 address

Because 94105 has dense multifamily development and several overlapping network types, the useful process is to identify the market first and then verify the building.

1. Check fiber and wired networks first

  • Check AT&T for fiber availability at the exact address.
  • Check Sonic for fiber service and building eligibility.
  • Check Xfinity for cable service and current plan tiers.
  • Check Astound because its footprint is smaller and property dependent.

2. Check building-oriented service separately

  • Check GFiber Webpass for the exact building.
  • Ask the building manager which providers are currently wired into the property.
  • Confirm whether service is available to the specific unit.
  • Do not assume a neighboring high-rise has the same provider list.

3. Compare fixed wireless separately

  • Check Verizon 5G Home Internet.
  • Check T-Mobile Home Internet.
  • Check Unwired, XNET and other local fixed-wireless providers where relevant.
  • Consider signal, capacity, equipment location and building construction.

4. Compare more than download speed

  • Upload speed
  • Latency
  • Network congestion
  • Equipment and Wi-Fi requirements
  • Installation terms
  • Regular versus introductory pricing
  • Building wiring and installation limitations

What to compare before choosing a 94105 connection

The strongest comparison in 94105 starts with identifying the physical network available to the building and then comparing service characteristics.

Fiber versus cable

Compare upload capacity

Sonic and AT&T fiber can provide symmetric or substantially higher upload capacity than traditional cable service. That difference can matter for cloud backups, large file transfers, video production and other upload-heavy use.

High-rise housing

Verify the building's network

In 94105, the network serving the street is only part of the question. A condominium or apartment building may have a specific set of providers wired into the property, and individual units may have different installation constraints.

Wireless alternatives

Compare 5G against wired service

Verizon and T-Mobile can provide alternatives where wireless eligibility exists, while Unwired and other local fixed-wireless networks add additional options. Compare their actual address-level plans against the wired networks rather than treating wireless coverage percentages as equivalent to fiber or cable availability.

Check the exact 94105 address

ZIP-level research identifies the local provider market. Building and address tools determine which networks can actually be ordered.

Sources and methodology

This page separates official provider information, government broadband mapping information, local geographic evidence and third-party ZIP-level datasets. Coverage percentages are reported with their source context instead of being presented as universal facts.

Government and local sources

  • FCC National Broadband Map and Broadband Data Collection guidance, which explains that fixed broadband providers submit location-level availability data and that the map reports availability rather than performance or affordability.
  • San Francisco official ZIP-code mapping identifying 94105 with Financial District South, Embarcadero and Rincon Hill.
  • San Francisco Rincon Hill Area Plan, used for local development context and the area's transition toward a dense mixed-use residential neighborhood.

Provider and ZIP-level broadband sources

  • Sonic's current San Francisco residential information describing its wholly owned 10-Gigabit fiber network and current service options.
  • Xfinity's current San Francisco information identifying 500 Folsom Street, San Francisco, CA 94105 as an Xfinity location.
  • Current September 2026 94105 provider data reporting approximately 73.9% AT&T, 52.9% Xfinity, 33.4% Astound, 100% Verizon, 99.7% Unwired, 53.3% XNET, 48.5% Etheric and 11.7% GFiber Webpass.
  • FCC-derived 94105 cable data reporting approximately 90.8% Xfinity cable and 15.15% Astound cable in the dataset reviewed.
  • A 94105 property record documenting Sonic and GFiber Webpass service at an individual San Francisco property, used only as building-level evidence rather than as a ZIP-wide coverage estimate.
Research limitation: ZIP-level broadband data is not a substitute for a provider's current address checker. The 94105 datasets reviewed have materially different reporting dates and coverage methodologies. In particular, Xfinity and Astound percentages differ between the current ZIP provider source and the FCC-derived cable dataset. Those differences are preserved here because reporting a single percentage without its methodology would create a false impression of precision.

94105 internet provider FAQ

Answers below distinguish ZIP-level evidence from what can actually be established for an individual San Francisco building or address.

What internet providers serve ZIP code 94105?
Current ZIP-level evidence identifies AT&T, Xfinity, Astound Broadband, Verizon, T-Mobile, Unwired, XNET, Etheric and GFiber Webpass among the providers in the 94105 market. Sonic also operates a 10-Gigabit fiber network in San Francisco and has property-level service evidence in 94105. The exact provider list for a building should be confirmed directly by address.
Is fiber internet available in 94105?
Fiber is an important part of the 94105 market. Sonic operates a 10-Gigabit fiber network in San Francisco, and AT&T is reported in current 94105 data with fiber service available in its broader San Francisco market. The exact building determines which fiber networks and tiers can actually be ordered.
Does Xfinity serve 94105?
Yes. Xfinity has direct evidence of service in 94105, including an Xfinity location at 500 Folsom Street. A November 2025 FCC-derived cable dataset reports approximately 90.8% Xfinity cable coverage, while a September 2026 ZIP provider source reports approximately 52.9% overall Xfinity availability. The difference reflects different source dates and methodologies, so neither number should be treated as a live building-level guarantee.
Does Astound Broadband serve 94105?
Astound appears in current ZIP-level broadband data for 94105. A September 2026 provider source reports approximately 33.4% availability, while a separate FCC-derived cable dataset reports approximately 15.15%. The consistent finding is that Astound has a smaller, partial wired footprint rather than universal ZIP coverage.
Is Verizon 5G Home Internet available in 94105?
A current September 2026 ZIP provider dataset reports Verizon 5G availability at approximately 100% in 94105. That is a coverage indicator, not a guarantee of identical signal or plan eligibility for every apartment. Verizon's current address check should be used to confirm service.
Is T-Mobile 5G Home Internet available in 94105?
Current San Francisco and 94105 provider data identify T-Mobile 5G Home Internet in the market. Fixed-wireless eligibility can depend on the exact address, serving site capacity and wireless conditions, so a ZIP listing should not be treated as a live order result.
What is GFiber Webpass in 94105?
GFiber Webpass is a building-oriented internet service with a smaller reported 94105 footprint. A current ZIP provider source reports approximately 11.7% availability, while a property record at 199 New Montgomery Street documents Webpass service. This illustrates why building-level research can identify an option that a general ZIP provider list may not fully explain.
Why is building-level verification especially important in 94105?
94105 includes dense apartment, condominium and mixed-use development in Financial District South, the Embarcadero and Rincon Hill. A provider network may be available in the surrounding area without being connected to every building or unit. Internal wiring and property-level provider arrangements can therefore affect the actual choices available to a resident.
Can two nearby buildings in 94105 have different providers?
Yes. Wired networks can follow different construction and building-entry paths, while wireless providers can produce different eligibility or performance results depending on the property. A building with Sonic, Xfinity and Webpass, for example, should not be assumed to have the same provider set as the building next door.
Is the fastest advertised speed necessarily the best connection?
Not necessarily. Download speed is only one measurement. Upload capacity, latency, congestion, equipment, installation requirements, regular pricing and the physical network serving the building can materially affect the usefulness of a connection.
Why do 94105 provider coverage percentages differ between sources?
Broadband datasets can use different reporting dates, geographic calculations, provider records and definitions of availability. In 94105, one current provider source reports Xfinity at approximately 52.9%, while an FCC-derived cable dataset reports approximately 90.8% Xfinity cable coverage. Astound is also reported at different levels in the two datasets. These figures should therefore remain source-specific rather than being averaged or presented as one exact percentage.
Why does this page use ZIP-level data instead of claiming exact coverage?
ZIP-level data is useful for identifying the provider market around 94105, but provider networks do not follow postal boundaries exactly. The FCC's own broadband mapping system provides location-level service information and explains that its data represents reported availability. A provider address checker and, for multifamily properties, building verification provide the more precise answer.
Availability disclaimer: Provider names, technologies, advertised speeds, pricing and availability can change. ZIP-level broadband information does not guarantee service at an individual address or unit. High-rise buildings, condominiums, apartment properties and mixed-use developments may have different network infrastructure and provider arrangements. Always confirm service, technology, speed, equipment requirements, installation conditions and current pricing directly with the provider before ordering.
