94108 Internet Providers

Broadband in 94108 serves a compact but unusually dense part of central San Francisco, including Chinatown, Nob Hill and the Union Square area. Current provider datasets identify Xfinity and AT&T as major wired providers, with Astound providing a smaller cable footprint. Sonic, T-Mobile, Verizon and several fixed-wireless providers add additional options, but their reported coverage differs substantially by dataset.

● 94108 is a small urban ZIP with many older and multifamily buildings. ZIP-level provider data is useful for mapping the market, but building wiring, network construction and the individual service address still determine what can actually be ordered.

What the 94108 broadband evidence shows

94108 has a different broadband pattern from a suburban ZIP. The area is compact, heavily built out and dominated by older urban buildings. Current secondary data identifies Xfinity and AT&T as major providers, while Astound, wireless networks and smaller fixed-wireless operators create additional coverage layers. The important finding is that the reported percentages do not agree across datasets, so the numbers are best used to identify network patterns rather than to make address-level claims.

Cable

Xfinity has a large reported wired footprint

A secondary dataset based on FCC data reports Xfinity cable availability at approximately 99.78% of 94108 using data through December 2024. A newer September 2026 provider dataset reports approximately 86%. The difference is substantial enough that neither figure should be presented as a live address-level percentage.

Fiber

Fiber exists, but ZIP-level data does not establish uniform coverage

Sonic operates a wholly owned 10-Gigabit fiber network in San Francisco, and AT&T confirms fiber availability in parts of the city with speeds up to 5 Gbps where available. Current 94108 secondary data reports relatively limited Sonic coverage compared with some other provider categories, while AT&T is reported more broadly when multiple AT&T technologies are combined.

Urban buildings

Building infrastructure matters unusually much in 94108

Chinatown contains many older buildings and SRO properties, while Nob Hill includes apartment, condominium, cooperative and hotel-style buildings. Historical reporting on Chinatown's digital divide has identified aging internal wiring and building-owner coordination as barriers to fiber upgrades. A network in the street does not by itself establish service inside an individual building or unit.

94108 provider comparison

The table separates current secondary coverage indicators from provider claims and address-level serviceability. Coverage percentages are not treated as live ordering results because the underlying datasets use different dates and methodologies.

Provider Technology 94108 evidence Advertised maximum What to verify
Xfinity
Broad cable footprint 		Cable One FCC-derived secondary dataset reports approximately 99.78% Xfinity cable coverage in 94108. A newer current provider dataset reports approximately 86%, showing why the source date matters. Up to 2 Gbps in current San Francisco offerings Exact address, available tier, upload speed and equipment terms
AT&T
Broad reported presence 		Fiber / IPBB / other AT&T categories A current secondary 94108 dataset reports approximately 90% AT&T availability, but the figure combines multiple AT&T service categories. AT&T separately confirms that fiber is available in parts of San Francisco. Up to 5 Gbps where fiber is available Whether the exact address qualifies for fiber rather than another AT&T technology
Astound Broadband
Partial cable footprint 		Cable FCC-derived secondary data reports approximately 17.90% cable coverage in 94108, while another current secondary dataset reports a footprint closer to 28.45%. Both indicate a substantially smaller footprint than Xfinity. Up to 1.5 Gbps in current reported 94108 data Whether the exact building falls within Astound's network
Sonic
Fiber network 		Fiber Sonic operates a wholly owned 10-Gigabit fiber network in San Francisco. A current secondary 94108 provider dataset reports approximately 4% Sonic availability, indicating that citywide Sonic network presence should not be interpreted as ZIP-wide residential service. Up to 10 Gbps Exact address, construction status and current Sonic plan
T-Mobile Home Internet
5G / fixed wireless 		5G fixed wireless Current secondary 94108 provider data reports approximately 53% T-Mobile home-internet availability. Wireless eligibility depends on the exact address, network capacity and radio conditions. Up to about 498 Mbps in current secondary reporting Address eligibility, available capacity and signal conditions
Verizon 5G Home Internet
Limited wireless footprint 		Fixed wireless Current secondary 94108 data reports approximately 29% Verizon home-internet availability. This is substantially narrower than the broadest wired coverage reported for the ZIP. Up to about 400 Mbps in current secondary reporting Exact address and current 5G Home Internet eligibility
XNET
Fixed wireless 		Fixed wireless A current secondary 94108 dataset reports approximately 53% XNET availability. Because this is a fixed-wireless service, coverage should be interpreted as a reported footprint rather than guaranteed service at every building. Up to 2 Gbps in current secondary reporting Exact address, building access and network capacity
Etheric Networks
Fixed wireless 		Fixed wireless Current secondary provider data reports approximately 49% Etheric Networks availability in 94108. The service footprint should be verified directly because fixed-wireless eligibility can depend on the location and network design. Up to 250 Mbps in current secondary reporting Exact address, line-of-sight and network footprint
Unwired LTD
Fixed wireless 		Fixed wireless A current secondary provider dataset reports Unwired availability across essentially all of 94108. This broad geographic indicator should still be checked against the exact building. Up to 300 Mbps in current secondary reporting Exact address and current service eligibility
Satellite providers
Broad geographic option 		Satellite Starlink, Viasat and HughesNet have broad geographic availability because they do not depend on the same neighborhood cable or fiber plant as wired providers. Provider and plan dependent Equipment location, sky visibility, latency and plan terms
ZIP-level interpretation: The 94108 datasets reviewed agree that multiple wired and wireless providers operate in the ZIP, but they do not produce identical coverage percentages. One FCC-derived dataset reports Xfinity cable at 99.78% and Astound at 17.90%, while a newer provider dataset reports approximately 86% Xfinity, 90% AT&T, 53% T-Mobile, 29% Verizon, 53% XNET, 49% Etheric, 100% Unwired and 4% Sonic. Those differences are evidence that source vintage, provider classification and methodology matter. They should not be converted into a claim that a particular 94108 building can order any listed service.

Internet providers serving the 94108 market

The provider descriptions below focus on the evidence that can be tied to 94108 or San Francisco. Citywide network information is not presented as proof of universal ZIP coverage.

Xfinity

Cable Large 94108 footprint Up to 2 Gbps reported

Xfinity is the most consistently documented large cable network in 94108. A secondary dataset based on FCC data through December 2024 reports 99.78% Xfinity cable coverage, while a newer provider dataset reports approximately 86%. The different results should not be treated as a contradiction about the existence of the network; they show that coverage estimates depend on the dataset and reporting period.

  • Cable is the primary residential technology reported for Xfinity.
  • Current San Francisco offerings include multi-gigabit tiers.
  • Upload performance can differ materially from fiber alternatives.
  • Building wiring and serviceable outlets still need to be confirmed.
Local evidence: One FCC-derived secondary dataset reports 99.78% Xfinity cable coverage in 94108. A current secondary provider source reports approximately 86%. Xfinity itself confirms San Francisco home internet service and directs customers to an address-level availability check.

AT&T

Fiber / IPBB San Francisco network Up to 5 Gbps fiber

AT&T has a significant San Francisco internet presence, but the distinction between AT&T service generally and AT&T Fiber matters in 94108. A current secondary dataset reports approximately 90% AT&T availability in the ZIP while combining multiple AT&T categories. AT&T's own San Francisco page confirms that fiber is available in parts of the city and that eligibility depends on the exact address.

  • AT&T Fiber is a separate network technology from older copper-based service.
  • AT&T currently lists fiber speeds up to 5 Gbps where available.
  • The 90% ZIP-level figure should not be read as 90% fiber coverage.
  • Address verification is necessary to identify the technology and tier.
Local evidence: AT&T's current San Francisco fiber page states that AT&T Fiber is available in parts of San Francisco and requires an address check. Current secondary 94108 data reports broader AT&T availability because it combines multiple AT&T service categories.

Astound Broadband

Cable Partial 94108 footprint Up to 1.5 Gbps reported

Astound is a smaller but locally relevant cable competitor in 94108. One FCC-derived secondary dataset reports approximately 17.90% cable coverage, while another current dataset reports approximately 28.45%. The estimates differ, but both place Astound well below the broadest Xfinity footprint in the ZIP.

  • Astound's reported 94108 service is primarily cable.
  • Its footprint is substantially smaller than the largest cable network.
  • Current secondary reporting lists up to approximately 1.5 Gbps.
  • Building-level eligibility must be confirmed independently.
Evidence standard: The 17.90% and 28.45% figures come from different secondary datasets and dates. The page uses them to establish that Astound has a partial 94108 footprint rather than selecting one figure as an exact current service boundary.

Sonic

Fiber San Francisco network Up to 10 Gbps

Sonic is important to investigate because it operates a wholly owned 10-Gigabit fiber network in San Francisco. That citywide network statement does not mean Sonic fiber is available throughout 94108. A current secondary provider dataset reports approximately 4% Sonic availability in the ZIP, which makes address-level verification particularly important before describing Sonic as a practical option for a specific building.

  • Sonic uses fiber rather than traditional cable infrastructure.
  • Sonic currently advertises symmetric speeds up to 10 Gbps.
  • Sonic states that its San Francisco network is wholly owned.
  • The reported 94108 footprint is much smaller than the citywide network footprint.
Local evidence: Sonic's current San Francisco page describes a wholly owned 10-Gigabit fiber network and provides an address-based availability checker. Current secondary 94108 data reports approximately 4% Sonic availability, so citywide Sonic coverage should not be used as a ZIP-wide assumption.

T-Mobile Home Internet

5G fixed wireless 94108 market presence Capacity-dependent

T-Mobile adds a fixed-wireless alternative to the wired networks in 94108. A current secondary provider dataset reports approximately 53% availability in the ZIP. Unlike cable and fiber, the service does not depend on a dedicated wired drop reaching every building, but eligibility can still change according to network capacity and wireless conditions.

  • No traditional cable or fiber drop is required to the residence.
  • Availability can vary between nearby buildings.
  • Capacity can affect whether an address is accepted for home service.
  • The provider's current address check is required before ordering.
Local evidence: Current secondary 94108 data reports approximately 53% T-Mobile home internet availability. The percentage is a ZIP-level coverage indicator, not a guarantee of service capacity at every building.

Verizon 5G Home Internet

Fixed wireless Limited ZIP footprint Address dependent

Verizon 5G Home Internet is another wireless alternative in the San Francisco market. Current secondary 94108 data reports approximately 29% availability. That is a materially narrower reported footprint than the broadest wired provider categories in the ZIP, so Verizon should be treated as a property-specific option.

  • Service uses Verizon's wireless network rather than cable infrastructure.
  • Coverage percentages are not live ordering results.
  • Local capacity and signal conditions can affect eligibility.
  • Verizon's address checker is required for current availability.
Local evidence: Current secondary 94108 provider data reports approximately 29% Verizon home-internet availability. A current address-level check is necessary before treating Verizon as available at a particular property.

94108 internet speed guide

In 94108, the advertised download number can hide important differences between cable, fiber and fixed wireless. Building type is also relevant: a multi-unit property may have a different practical installation path from a detached or recently renovated structure.

100–300

Mbps

Enough for ordinary browsing, video calls, streaming and lighter household use when the connection is stable.

500 Mbps

Mbps

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

1–2 Gbps

High-capacity plans

Relevant for larger households, extensive cloud use, large downloads and homes with many active devices.

5–10 Gbps

Multi-gig fiber

Available only where a qualifying fiber network reaches the property and the home's router, Ethernet or Wi-Fi infrastructure can use it.

Do not compare download speed alone. In 94108, Sonic and AT&T fiber can have very different upload characteristics from cable service. Fixed wireless has another performance profile, with capacity and radio conditions affecting results. Equipment, latency, installation, recurring pricing and building wiring should all be considered.

Connection types in 94108

The ZIP combines established cable infrastructure with fiber networks, fixed wireless and satellite. The unusually dense building environment makes the distinction between network coverage and building serviceability especially important.

Fiber

Sonic operates a wholly owned 10-Gigabit fiber network in San Francisco, while AT&T confirms fiber service in parts of the city with speeds up to 5 Gbps where available. Current 94108 data does not establish that either fiber network reaches every building in the ZIP.

Cable

Xfinity is the most broadly documented cable network in the 94108 sources reviewed. Astound also has a partial cable footprint. The two networks do not cover the ZIP identically, making an individual building check more useful than a ZIP-wide provider list.

5G / fixed wireless

T-Mobile and Verizon provide wireless home-internet alternatives, while XNET, Etheric and Unwired are also reported by current secondary provider data. Fixed wireless can depend on capacity, signal and installation conditions rather than only street-level network presence.

Satellite

Satellite services such as Starlink, Viasat and HughesNet have broad geographic availability in 94108. Their coverage does not depend on the local cable or fiber plant, although latency, equipment placement and plan characteristics differ from wired broadband.

What is different about broadband in 94108?

94108 is a compact central San Francisco ZIP that includes Chinatown, Nob Hill and the Union Square area. Its physical density and building history create broadband conditions that are different from lower-density residential ZIP codes elsewhere in the city.

1

94108 is a small, dense urban ZIP

ZIP-level geographic sources place 94108 at roughly 0.28 square miles and associate it with Chinatown, Nob Hill and Downtown San Francisco or Union Square. Provider networks therefore operate across a very compact geography with a high concentration of buildings rather than a large spread of detached homes.

2

Chinatown's building stock affects broadband upgrades

Reporting on Chinatown's digital divide has identified older buildings, SRO housing and difficult internal-wiring projects as obstacles to broadband upgrades. A provider may have network infrastructure in the street while the building still requires owner coordination or interior construction before a newer connection can be delivered.

3

SRO and multifamily housing makes unit-level verification important

94108 contains numerous SRO and multifamily properties. Chinatown Community Development Center identifies properties such as 937 Clay, a 71-unit SRO building, and 1005 Powell, a 64-unit SRO property. Internet service in these buildings can involve shared infrastructure, building management and internal wiring that a ZIP-level coverage percentage cannot describe.

4

Coverage datasets disagree more than the provider list suggests

One FCC-derived secondary source reports Xfinity cable at 99.78% and Astound at 17.90% in 94108. A newer secondary dataset reports different figures, including approximately 86% Xfinity, 90% AT&T, 53% T-Mobile, 29% Verizon and 4% Sonic. The useful conclusion is not that one number is automatically correct, but that data vintage and classification must be disclosed.

5

Fiber availability should be investigated building by building

Sonic confirms a wholly owned 10-Gigabit fiber network in San Francisco, while AT&T confirms fiber availability in parts of the city. Neither statement establishes universal 94108 fiber coverage. In a ZIP with historic buildings, apartments, SROs and renovated properties, the exact building is the meaningful unit for final verification.

94108 local broadband findings

These findings explain what the available ZIP-level evidence establishes and where the evidence stops short of proving address-level service.

Finding Evidence What it means for a 94108 address
Xfinity cable FCC-derived secondary data reports 99.78%; newer secondary data reports approximately 86% Xfinity is a major wired network to check, but the differing percentages should not be treated as live address guarantees.
AT&T Current secondary data reports approximately 90% AT&T availability across combined service categories AT&T should be checked independently to determine whether the property qualifies for fiber or another AT&T technology.
Astound Broadband FCC-derived data reports 17.90%; another current source reports approximately 28.45% Astound provides a partial cable alternative, but its footprint is not ZIP-wide.
Sonic fiber Sonic operates a wholly owned 10-Gigabit San Francisco network; current secondary 94108 data reports approximately 4% Sonic is worth checking at the address, but San Francisco-wide network presence does not establish 94108-wide residential availability.
T-Mobile 5G Current secondary provider data reports approximately 53% availability Wireless service is a meaningful additional option, but eligibility depends on capacity and the exact location.
Verizon 5G Current secondary provider data reports approximately 29% availability Verizon is a more limited reported wireless option that requires an address-level check.
Smaller fixed wireless Current secondary data reports XNET, Etheric Networks, Unwired and GeoLinks in parts of the ZIP Smaller providers add local competition that may not appear in a simple national-provider comparison.
Building infrastructure Chinatown contains older buildings and substantial SRO housing; local reporting has documented interior-wiring barriers to fiber upgrades A provider shown as available at the ZIP or nearby street may still require building-level construction or owner coordination.

Neighborhoods and development patterns inside 94108

The neighborhood references below describe the geography and building environment of 94108. They are not provider-coverage boundaries.

Chinatown The core 94108 area includes dense historic blocks, mixed-use buildings and substantial SRO housing. Older construction and interior wiring can affect the practical path from a street network to an individual unit.
Nob Hill 94108 includes the Nob Hill area, with apartment, condominium, cooperative and larger residential buildings. Provider availability can therefore differ between buildings even on nearby streets.
Union Square / Downtown The southern portion of the 94108 geography approaches the Union Square and downtown environment, where residential buildings can coexist with hotels, retail and commercial properties. Residential service records should be distinguished from business availability.
California Street corridor The California Street area crosses the Nob Hill/Chinatown geography and includes substantial older building stock. A neighborhood or street reference cannot establish which provider reaches each individual property.
Powell Street / Chinatown edge Properties around Powell Street transition between Chinatown and Nob Hill building environments. Existing SRO and multifamily properties can have different internal wiring and management arrangements.
Clay, Sacramento and Stockton corridors These central 94108 corridors include historic mixed-use and residential properties. Building age, renovation history and unit configuration can matter when a provider needs to install or upgrade internal wiring.
Why this matters: 94108 is not a uniform residential subdivision. The ZIP contains historic buildings, SROs, apartment buildings, condominiums, cooperatives, commercial properties and renovated housing. A broadband network reaching one building or block does not prove identical serviceability at the next address.

How to verify internet service at a 94108 address

The most useful sequence is to identify the networks reported in the ZIP and then determine which of them actually serve the building and unit.

1. Check the wired networks first

  • Check Xfinity for current cable service and available tiers.
  • Check AT&T for fiber and determine which AT&T technology is offered.
  • Check Astound because its footprint covers only part of 94108.
  • Check Sonic separately because its San Francisco fiber network is not ZIP-wide.

2. Compare fixed wireless separately

  • Check T-Mobile Home Internet at the exact address.
  • Check Verizon 5G Home Internet independently.
  • Check smaller providers such as XNET, Etheric or Unwired where relevant.
  • Do not infer wireless eligibility from a neighboring building.

3. Verify the building's internal infrastructure

  • Ask whether the provider already serves the building.
  • For SROs and apartments, ask whether service reaches the individual unit.
  • Determine whether installation requires owner or property-manager access.
  • Check whether the advertised connection uses existing or new wiring.

4. Treat ZIP-level data as a research layer

The FCC National Broadband Map uses provider-reported, location-level fixed broadband availability data and can show the providers, technologies and advertised speeds reported at a particular location. ZIP-level percentages from secondary datasets are useful for understanding the broader market, but they are not a substitute for checking the exact address and unit.

What to compare before choosing a 94108 connection

The most useful comparison in 94108 begins with the network and building that can actually serve the property, not the highest number appearing in a ZIP-wide provider table.

Fiber versus cable

Compare upload capacity

Sonic and AT&T fiber can provide symmetric or substantially stronger upload performance than traditional cable. This can matter for cloud backups, large file transfers, video production and upload-heavy work.

Historic buildings

Ask what reaches the unit

In older Chinatown and Nob Hill properties, the network outside the building is only one part of the installation. Existing internal wiring, building access and property arrangements can affect the service that can actually be installed.

Wireless alternatives

Check capacity separately

T-Mobile, Verizon and smaller fixed-wireless providers can expand the choices at buildings where wired options are limited. Wireless service should still be checked at the exact address because eligibility and capacity can vary by location.

Check the exact 94108 address

ZIP-level research identifies the local market. Provider address tools determine what can actually be ordered at the property.

Check Availability

Sources and methodology

This page gives greater weight to official provider information for current network and plan claims, while using FCC-derived and other ZIP-level datasets as a secondary coverage layer.

Official provider and federal sources

  • AT&T San Francisco Fiber — AT&T states that fiber is available in parts of San Francisco, lists speeds up to 5 Gbps where available and requires an address check for serviceability.
  • Sonic San Francisco Internet — Sonic describes its San Francisco network as a wholly owned 10-Gigabit fiber network and provides an address-based availability tool.
  • Xfinity San Francisco Internet — Xfinity confirms San Francisco home internet service and provides current local pricing and address-level availability guidance.
  • Astound Broadband — provider information and address-level service checking.
  • FCC National Broadband Map — the FCC's location-level broadband map reports provider-submitted fixed broadband availability, technologies and advertised speeds.

94108 ZIP-level and local evidence

  • A secondary FCC-data-based 94108 source reports approximately 99.78% Xfinity cable coverage and 17.90% Astound cable coverage, using data through December 2024.
  • A current September 2026 secondary provider dataset reports approximately 90% AT&T, 86% Xfinity, 53% T-Mobile, 29% Verizon, 53% XNET, 49% Etheric Networks, 100% Unwired, 61% GeoLinks and 4% Sonic availability in 94108.
  • San Francisco housing and community sources document substantial SRO and multifamily housing in the Chinatown portion of 94108, including 937 Clay and 1005 Powell.
  • Reporting on Chinatown's digital divide has documented older building stock and internal-wiring challenges that can complicate fiber upgrades.
  • Coverage percentages are retained as dataset outputs. They are not converted into claims that a particular address or unit can order service.
Research limitation: ZIP code 94108 is a postal geography rather than a broadband service boundary. The FCC explains that fixed broadband availability is reported at individual location points, while secondary ZIP datasets aggregate provider information differently. The resulting percentages can therefore differ substantially. For a specific 94108 property, the provider's current address checker and building-level service information should take precedence.

94108 internet provider FAQ

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

What internet providers serve ZIP code 94108?
Current ZIP-level evidence identifies Xfinity, AT&T, Astound Broadband, Sonic, T-Mobile, Verizon and several smaller fixed-wireless providers. Satellite services also have broad geographic availability. The exact provider list for a building should be confirmed by address because 94108 contains different network and building conditions.
Is AT&T Fiber available in 94108?
AT&T states that fiber is available in parts of San Francisco and lists speeds up to 5 Gbps where available. Current secondary data also reports AT&T service in 94108, but that ZIP-level figure combines multiple AT&T service categories. The address checker is required to determine whether a specific 94108 property receives fiber.
Is Sonic Fiber available in 94108?
Sonic operates a wholly owned 10-Gigabit fiber network in San Francisco. A current secondary 94108 dataset reports approximately 4% Sonic availability. That figure should not be treated as an exact service boundary, but it does show why San Francisco-wide Sonic coverage cannot be assumed to mean Sonic fiber reaches every 94108 building.
Does Xfinity serve 94108?
Yes. Xfinity has a large reported cable footprint in 94108. One FCC-derived secondary dataset reports approximately 99.78% cable coverage, while a newer secondary provider dataset reports approximately 86%. The difference reflects source and methodology differences, so individual properties should still be checked directly.
Does Astound Broadband serve 94108?
Yes, but its reported footprint is substantially smaller than the broadest Xfinity coverage. One FCC-derived secondary dataset reports approximately 17.90% Astound cable coverage, while another current source reports approximately 28.45%. The consistent finding is that Astound is a partial ZIP-level option rather than a universal provider.
Is T-Mobile 5G Home Internet available in 94108?
Current secondary provider data reports T-Mobile home-internet service across approximately 53% of 94108. Fixed-wireless eligibility depends on the exact location and available network capacity, so a nearby T-Mobile customer does not establish eligibility at another building.
Is Verizon 5G Home Internet available in 94108?
Current secondary provider data reports approximately 29% Verizon home-internet availability in 94108. This is a ZIP-level indicator, not a live eligibility result. Verizon's current address checker is needed to determine whether a particular building qualifies.
Can two nearby buildings in 94108 have different providers?
Yes. Fiber and cable networks can have different building footprints, while fixed-wireless eligibility can depend on capacity and signal conditions. In addition, older multifamily and SRO buildings may have internal wiring or property-management arrangements that affect which services can be installed.
Why is building-level verification especially important in Chinatown?
Chinatown contains substantial older building stock and SRO housing. Local reporting has documented cases where bringing newer fiber service into older buildings requires interior-wiring upgrades and coordination with building owners or managers. A network available at the street therefore does not automatically mean every unit can receive the same technology.
Why do 94108 provider coverage percentages differ between sources?
Broadband datasets use different update dates, provider records, geographic aggregation methods and technology classifications. For 94108, one FCC-derived dataset reports approximately 99.78% Xfinity cable coverage and 17.90% Astound coverage, while newer secondary data produces different results for several providers. These numbers should therefore be used as coverage indicators rather than exact address-level measurements.
Is the fastest advertised speed necessarily the right connection?
Not necessarily. Download speed is only one measure. Upload capacity, latency, network technology, congestion, equipment, installation, recurring pricing and whether the service can actually be delivered inside the building can materially affect the usefulness of a plan.
Why does this page use ZIP-level data instead of claiming exact coverage?
ZIP-level data is useful for identifying the broadband market around 94108, but provider networks do not follow postal boundaries exactly. The FCC's National Broadband Map uses location-level provider reporting, while secondary ZIP datasets aggregate that information differently. The most precise answer for a resident comes from checking the provider against the exact street address, building and unit.
Availability disclaimer: Provider names, technologies, advertised speeds, pricing and availability can change. ZIP-level broadband information does not guarantee service at an individual address. Apartment buildings, SROs, condominiums, cooperatives, hotels and other multifamily properties may have different network infrastructure and installation requirements. Always confirm service, technology, speed, equipment requirements and current pricing directly with the provider before ordering.
