Why can two buildings in 94107 have different internet options?

94107 combines older Potrero Hill housing, former industrial and mixed-use areas in Dogpatch, dense newer multifamily development around Mission Bay and South Beach, and commercial and residential areas near SoMa. Broadband networks follow physical infrastructure and building connections rather than ZIP boundaries, so nearby properties can have different serviceable technologies.

San Francisco ZIP 94107

94107 Internet Providers

Q: What internet providers serve ZIP code 94107?

Current ZIP-level broadband sources identify Xfinity, Astound Broadband, Sonic, AT&T, T-Mobile, Verizon and additional fixed-wireless and satellite providers in the 94107 market. Xfinity has the broadest reported cable footprint, while Sonic and AT&T provide fiber in portions of the ZIP. Exact availability depends on the service address.

Q: Is Sonic Fiber available in 94107?

Yes. Current ZIP-level broadband data reports Sonic fiber service in approximately 14% of 94107. Sonic also operates a wholly owned fiber network in San Francisco. The ZIP percentage is a coverage indicator rather than an address-level guarantee.

Q: Does Xfinity serve 94107?

Yes. Current ZIP-level datasets report Xfinity cable availability at approximately 99.7% to 99.68% of 94107. Some addresses also have Xfinity fiber-class service. Individual buildings should still be checked directly because coverage data does not establish current serviceability for every unit.

Q: Does Astound Broadband serve 94107?

Yes. Current ZIP-level datasets identify Astound Broadband cable service in 94107, with reported coverage ranging from approximately 44% to 58% depending on the dataset and vintage reviewed. Astound requires an address-level check for final serviceability.

Q: Is AT&T Fiber available in 94107?

AT&T has both fiber and older AT&T broadband categories reported in San Francisco. Current 94107 data reports AT&T fiber in a smaller portion of the ZIP, while other AT&T technologies have a broader footprint. The exact address determines whether fiber is offered.

Q: Is T-Mobile Home Internet available in 94107?

Current ZIP-level provider data identifies T-Mobile 5G home internet in 94107, with one current dataset reporting approximately 59% availability. Fixed-wireless eligibility can depend on address, network capacity and wireless conditions.

Q: Is Verizon 5G Home Internet available in 94107?

Current ZIP-level provider data identifies Verizon 5G home internet in the 94107 market. Coverage estimates vary between datasets, so Verizon's address-level availability checker should be used before treating service as available at a particular property.

Broadband in 94107 includes a very broad Xfinity cable footprint, substantial Astound cable coverage, smaller Sonic and AT&T fiber footprints, and fixed-wireless options from providers including T-Mobile and Verizon. The ZIP's mix of Potrero Hill, Dogpatch, Mission Bay and South of Market-area development makes the building itself especially important when comparing service.

● ZIP-level data shows which networks report service in 94107, but it cannot establish which providers reach a particular apartment, condominium, office-to-residential conversion or house.

What the 94107 broadband evidence shows

94107 has a different provider pattern from many San Francisco ZIP codes. Xfinity's cable network is reported across nearly the entire ZIP, while Astound provides a second cable footprint across a substantial portion. Fiber is present but more geographically constrained: current ZIP-level data reports Sonic fiber at about 14.2%, while AT&T fiber is also present in a smaller portion of the ZIP. Wireless networks add another layer of competition that can vary by building and network capacity.

Cable

Xfinity reaches almost the entire reported ZIP

Current 94107 broadband datasets report Xfinity cable coverage at approximately 99.7% to 99.68% of the ZIP. The network is therefore the most broadly documented wired option in 94107. That percentage describes reported coverage, not a guarantee that every unit can immediately order every Xfinity tier.

Fiber

Fiber exists, but it is not uniform across 94107

Sonic fiber is reported at approximately 14.2% of 94107 in a current FCC-derived ZIP dataset. AT&T also reports fiber service in San Francisco, with 94107 data showing a smaller fiber footprint than its broader legacy broadband presence. Fiber eligibility therefore needs a direct property-level check.

Competition

Astound and wireless networks broaden the local market

Astound cable is reported across roughly 44% to 58% of 94107 depending on the dataset reviewed. T-Mobile, Verizon, XNET, Etheric and Unwired also appear in current ZIP-level records. This means the provider list can be substantially longer than the options available at one building.

94107 provider comparison

The figures below are ZIP-level coverage indicators from current or recently updated broadband datasets. They are useful for understanding the local market but should not be interpreted as live ordering results. Where datasets disagree, the difference is identified instead of being presented as a single exact coverage number.

Provider	Technology	94107 evidence	Advertised maximum	What to verify
Xfinity Broad ZIP footprint	Cable	Current 94107 datasets report approximately 99.7% to 99.68% cable coverage. One source reports 99.7%, while another reports 99.68% of homes.	Up to 2 Gbps in current 94107 reporting	Exact address, available tier, upload speed and equipment terms
Astound Broadband Substantial cable footprint	Cable	Current ZIP-level sources report Astound cable coverage ranging from approximately 44.1% to 58.07% of 94107.	Up to 1.5 Gbps	Whether the exact building is connected to Astound's network
Sonic Fiber ZIP presence	Fiber	Current FCC-derived ZIP data reports Sonic fiber availability at approximately 14.22% of 94107. Sonic separately confirms its wholly owned 10-Gigabit fiber network in San Francisco.	Up to 10 Gbps in San Francisco where available	Exact address, network construction and current plan
AT&T Fiber + legacy broadband	Fiber / IPBB / wireless	94107 datasets report both AT&T fiber and broader AT&T broadband categories. One ZIP source reports approximately 12.5% AT&T fiber coverage, while older AT&T technologies have a substantially broader footprint.	Up to 5 Gbps fiber where available	Whether the property receives fiber rather than legacy service
T-Mobile Home Internet 5G / fixed wireless	5G fixed wireless	A current 94107 provider dataset reports T-Mobile 5G home internet availability at approximately 59% of the ZIP.	Up to about 498 Mbps in current ZIP-level reporting	Address eligibility, signal and network capacity
Verizon 5G Home Internet Wireless alternative	5G fixed wireless	Current ZIP-level records identify Verizon 5G Home Internet in 94107. Coverage estimates differ by dataset, so the ZIP figure should not be treated as live address eligibility.	Up to 300–400 Mbps in current ZIP-level reporting	Exact address, available plan and network capacity
XNET Fixed wireless	Fixed wireless	Current 94107 provider data identifies XNET as a local fixed-wireless option with a meaningful reported footprint.	Up to 2 Gbps in current ZIP-level reporting	Exact address, equipment and wireless path
Etheric Networks Fixed wireless	Fixed wireless	Etheric appears in current 94107 provider data with a smaller reported footprint than Xfinity or Astound.	Up to 250 Mbps in current ZIP-level reporting	Address, network footprint and installation conditions
Unwired Ltd Fixed wireless	Fixed wireless	Current ZIP-level data identifies Unwired as a widely reported fixed-wireless provider in 94107.	Up to 300 Mbps in current ZIP-level reporting	Exact property and wireless service conditions

Provider and plan dependent	Equipment location, sky visibility, latency and plan terms

ZIP-level interpretation: 94107 has an unusually strong cable baseline, but the ZIP is not a one-network market. Xfinity is reported across nearly all of the ZIP, Astound reaches a substantial secondary portion, and fiber and wireless options introduce additional competition at selected properties. The precise combination available at a building cannot be inferred from the ZIP-wide provider list.

Internet providers serving the 94107 market

The provider descriptions below focus on what current 94107 data establishes and where the evidence becomes less certain at the property level.

Xfinity

Cable Approximately 99.7% ZIP coverage Up to 2 Gbps reported

Xfinity is the most broadly reported wired provider in 94107. Current ZIP-level sources place its cable footprint at approximately 99.7% to 99.68% of homes. A smaller Xfinity fiber footprint is also reported in the ZIP, but cable remains the defining Xfinity technology across 94107.

Cable coverage is reported across almost the entire ZIP.
Current 94107 datasets report download tiers reaching approximately 2 Gbps.
Upload capacity can vary substantially by plan and network type.
Older and newer multifamily buildings may have different internal wiring.

Local evidence: Current 94107 broadband datasets report Xfinity cable availability at approximately 99.68% to 99.7%. Another ZIP-level source reports current download tiers up to 2,000 Mbps.

Astound Broadband

Cable Partial 94107 footprint Up to 1.5 Gbps

Astound is the second major cable network documented in 94107. Coverage estimates vary materially by source: one current dataset reports about 44.1%, while another reports approximately 58.07%. Rather than selecting one number as definitive, the consistent finding is that Astound reaches a substantial part of the ZIP but not every property.

Astound provides cable service across a significant part of 94107.
Its reported footprint is smaller than Xfinity's.
Current ZIP-level data reports up to approximately 1.5 Gbps.
Astound's address checker is necessary to determine building eligibility.

Evidence standard: The 44.1% and 58.07% estimates come from different broadband datasets. Their disagreement is treated as a measurement difference rather than evidence that one percentage is an exact live figure for every address.

Sonic

Fiber Approximately 14.2% ZIP coverage 10-Gigabit San Francisco network

Sonic provides one of the most significant fiber alternatives to cable in the San Francisco market, but its reported footprint inside 94107 is much smaller than its citywide network presence. Current ZIP-level data reports Sonic fiber at approximately 14.22% of 94107. Sonic itself describes a wholly owned 10-Gigabit fiber network in San Francisco.

Sonic's 94107 footprint is fiber rather than traditional cable.
Current Sonic San Francisco information describes service up to 10 Gbps where available.
Fiber provides symmetric upload/download capability on applicable service.
The 14.22% ZIP figure does not identify which individual streets qualify.

Local evidence: A current ZIP-level dataset reports Sonic fiber at approximately 14.22% of 94107, while Sonic's San Francisco service page describes its wholly owned 10-Gigabit fiber network and requires an address check.

AT&T

Fiber + IPBB Partial fiber footprint Up to 5 Gbps fiber

AT&T has a more complicated 94107 footprint because ZIP-level datasets distinguish between AT&T fiber and older broadband technologies. Current 94107 data reports AT&T fiber in approximately 12.5% of the ZIP in one dataset, while AT&T's broader legacy footprint is much larger. The practical question for a resident is therefore not simply whether AT&T appears in 94107, but which AT&T technology reaches the address.

AT&T Fiber is present in a portion of the ZIP.
Legacy AT&T broadband categories cover a much larger area.
Fiber service can provide symmetric multi-gigabit speeds where offered.
An address check is necessary to distinguish fiber from other AT&T service.

Local evidence: Current 94107 provider data reports AT&T fiber at approximately 12.5% of the ZIP in one dataset. AT&T's San Francisco information confirms that fiber availability is address dependent.

T-Mobile Home Internet

5G fixed wireless Approximately 59% reported Capacity dependent

T-Mobile provides a significant fixed-wireless alternative in 94107. One current ZIP-level source reports approximately 59% T-Mobile 5G home internet availability. Unlike cable plant, however, a wireless footprint can be affected by network capacity, radio conditions and the precise service location.

No dedicated neighborhood cable or fiber drop is required.
Eligibility can differ between nearby buildings.
Performance depends on network conditions as well as the service plan.
The current address checker is more precise than the ZIP percentage.

Local evidence: A current 94107 provider dataset reports T-Mobile 5G home internet at approximately 59% availability. The figure should be interpreted as a ZIP-level coverage estimate rather than an ordering guarantee.

Verizon 5G Home Internet

Fixed wireless 94107 market presence Address dependent

Verizon is another fixed-wireless option documented in 94107. Current provider datasets differ considerably in their reported Verizon footprint, which is a useful reminder that ZIP-level wireless coverage should not be treated as equivalent to live home-internet eligibility. Verizon's address-level check is the appropriate final test.

Service uses Verizon's wireless network rather than neighborhood cable plant.
Wireless capacity can change eligibility independently of wired coverage.
Building construction and signal conditions can affect service.
The current Verizon address checker should be used for final verification.

Local evidence: Verizon 5G home internet appears in current 94107 provider records. Because different datasets report materially different coverage levels, this page does not present a single ZIP percentage as definitive.

94107 internet speed guide

Speed requirements depend on household activity, but 94107 residents have an additional consideration: the difference between cable, fiber and fixed wireless can be more important than the advertised download number alone.

100–300

Mbps

Suitable for ordinary browsing, video calls, streaming and smaller households 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 to larger households, frequent large downloads and homes with many active devices, where the local network and equipment can actually use the additional capacity.

5–10 Gbps

Multi-gig fiber

Available only where a qualifying fiber network reaches the property. Sonic and AT&T advertise multi-gigabit fiber in San Francisco, but ZIP-level presence does not establish property-level eligibility.

Do not compare download speed alone. A 2 Gbps cable plan and a multi-gigabit fiber plan can have very different upload capacity, latency characteristics and network architecture. In 94107, the technology reaching the building can therefore matter as much as the headline download speed.

Connection types in 94107

The ZIP has one of the more varied broadband mixes in the San Francisco market: nearly universal reported Xfinity cable, substantial Astound cable coverage, smaller fiber footprints and several fixed-wireless networks.

Fiber

Sonic and AT&T are the principal fiber providers to investigate in 94107. Current ZIP-level data reports Sonic at about 14.2%, while AT&T fiber is also reported in a smaller portion of the ZIP. The exact building determines whether fiber can actually be ordered.

Cable

Cable is the dominant wired technology in 94107. Xfinity is reported across approximately 99.7% of the ZIP, while Astound reaches a substantial secondary footprint estimated at roughly 44% to 58% depending on the dataset.

5G / fixed wireless

T-Mobile and Verizon provide wireless home-internet alternatives, while XNET, Etheric and Unwired also appear in current ZIP-level records. Wireless eligibility depends on address, network capacity and local radio conditions.

Satellite

Starlink, Viasat and HughesNet are geographically available in 94107. Satellite service is structurally independent of neighborhood cable and fiber plant, although latency, equipment location and plan terms differ from wired broadband.

What is different about broadband in 94107?

94107 is not a uniform residential ZIP. It combines established Potrero Hill blocks with Dogpatch and Central Waterfront redevelopment, dense Mission Bay and South Beach-area housing, and portions of the eastern SoMa environment. Those differences matter because broadband infrastructure follows individual buildings and network routes rather than the ZIP boundary.

94107 combines older neighborhoods with major newer development

San Francisco planning documents describe the Central Waterfront and Dogpatch as areas accommodating new housing and neighborhood commercial services while retaining historic industrial and Production, Distribution and Repair uses. The eastern neighborhoods planning framework also includes Showplace Square, Potrero Hill and Central Waterfront areas. This creates a mix of older buildings, converted industrial properties and newer multifamily construction.

Xfinity is the dominant documented cable network

Current 94107 datasets report Xfinity cable coverage at approximately 99.7% to 99.68%. That is materially broader than the reported footprints of Sonic fiber or Astound cable. For many 94107 properties, Xfinity is therefore the baseline wired network against which other providers should be checked.

Astound creates meaningful cable competition, but not everywhere

Astound is reported at approximately 44.1% in one current 94107 source and 58.07% in another. The difference likely reflects source vintages, methodology and coverage definitions. The useful conclusion is narrower: Astound is a substantial secondary cable network in 94107, but it does not have the same ZIP-wide footprint reported for Xfinity.

Sonic fiber is concentrated within part of the ZIP

Current ZIP-level data reports Sonic fiber at approximately 14.22% of 94107. That is large enough to make Sonic relevant to a property search, but small enough that a ZIP-wide statement such as "Sonic is available in 94107" is incomplete without explaining the limited reported footprint.

Mission Bay and newer multifamily buildings change the serviceability question

94107 is associated with portions of the broader Mission Bay and eastern waterfront development pattern. Newer multifamily properties can have structured wiring, building-level provider arrangements, shared telecom rooms or other infrastructure that makes building verification more useful than relying on a neighborhood coverage map.

94107 local broadband findings

The findings below separate what ZIP-level broadband evidence establishes from what still requires a property-level provider check.

Finding	Evidence	What it means for a 94107 address
Xfinity cable	Current ZIP sources report approximately 99.7% to 99.68% cable coverage	Xfinity is the most broadly documented wired option in 94107, but exact building service should still be verified.
Astound Broadband	Current ZIP sources report approximately 44.1% to 58.07% cable coverage	Astound is a meaningful second cable network for many properties, but its footprint is not ZIP-wide.
Sonic fiber	Current ZIP-level data reports approximately 14.22% fiber coverage	A smaller portion of 94107 has Sonic fiber; address verification is necessary to determine whether a property falls inside the footprint.
AT&T Fiber	Current ZIP data reports a smaller AT&T fiber footprint alongside broader legacy AT&T service	AT&T should be checked separately because the presence of AT&T in the ZIP does not identify the technology available at the address.
T-Mobile 5G	Current 94107 provider data reports approximately 59% availability	T-Mobile is a significant wireless alternative, but eligibility can depend on capacity and address.
Verizon 5G	Current provider datasets identify Verizon 5G service, with differing coverage estimates	Verizon should be checked independently rather than relying on a single ZIP-wide percentage.
Fixed wireless alternatives	XNET, Etheric and Unwired appear in current 94107 provider records	Some properties have additional wireless choices that may not appear in a simple cable/fiber comparison.

Neighborhoods and development patterns inside 94107

Neighborhood labels are useful for understanding the ZIP's physical character, but broadband infrastructure still needs to be checked at the property level.

Potrero Hill Established residential areas form an important part of the 94107 geography. Older housing and block-by-block utility infrastructure make address-level provider checks more precise than ZIP averages.

Dogpatch Dogpatch combines historic industrial and residential development with newer housing and mixed-use construction. Different building vintages can have different internal telecom arrangements.

Mission Bay Portions of Mission Bay use ZIP 94107 while other portions use 94158. Newer multifamily development means building-level infrastructure can be particularly important when evaluating provider options.

South Beach / eastern SoMa edge Dense residential and mixed-use development near the northeastern portion of the ZIP creates a different housing and building environment from the lower-density portions of Potrero Hill.

Central Waterfront San Francisco planning documents describe the Central Waterfront as transitioning in portions from industrial uses toward a mixed-use environment while retaining important industrial areas.

Showplace Square / Potrero area The eastern-neighborhood planning framework treats Showplace Square and Potrero Hill as distinct planning areas with changing housing, employment and land-use patterns that can affect building infrastructure.

Why this matters: 94107 includes multiple development patterns rather than one uniform residential environment. A cable network may cover almost the entire ZIP while fiber reaches only selected buildings, and newer multifamily properties may have different internal telecom arrangements than older Potrero Hill or Dogpatch buildings.

How to verify internet service at a 94107 address

Start with the networks documented in the ZIP and then verify the exact building and unit. This is especially important in 94107 because cable, fiber and fixed-wireless footprints overlap differently.

1. Check the wired networks first

Check Xfinity for cable service and current plan tiers.
Check Astound because its footprint overlaps only part of 94107.
Check Sonic for fiber availability.
Check AT&T to determine whether fiber or another AT&T technology is offered.

2. Compare fixed wireless separately

Check T-Mobile Home Internet at the exact address.
Check Verizon 5G Home Internet independently.
Consider XNET, Etheric or Unwired where applicable.
Do not infer wireless home-internet eligibility from ordinary mobile coverage alone.

3. Compare more than download speed

Upload speed
Latency
Data caps or network-management policies
Equipment and Wi-Fi requirements
Installation terms
Regular pricing after introductory offers

4. Treat ZIP-level data as a research layer

FCC and other broadband datasets are useful for understanding the 94107 provider landscape. They can show that a provider reports service somewhere inside the ZIP without proving that the network reaches a particular apartment, condominium unit or house. Provider address checkers should therefore take precedence for final verification.

What to compare before choosing a 94107 connection

The local provider mix makes the physical network reaching the property an important part of the comparison.

Fiber versus cable

Compare upload capacity

Sonic and AT&T fiber can offer much higher upload capacity than traditional cable tiers where fiber is actually available. This matters for cloud backups, large file transfers, remote work and other upload-heavy uses.

Two cable networks

Check Xfinity and Astound separately

Xfinity reaches almost all of the ZIP according to current coverage datasets, while Astound reaches a substantial but smaller share. A building may have both, only one, or neither depending on the network plant and property connection.

Multifamily housing

Verify the building and unit

Newer Mission Bay, Dogpatch and eastern 94107 multifamily properties can have building-level telecom arrangements that differ from nearby houses or older buildings. Confirm service for the actual building and unit rather than relying on a ZIP-wide provider list.

Check the exact 94107 address

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

94107 ZIP-level broadband data

Current 94107 provider data reports Xfinity cable coverage at approximately 99.68% to 99.7%.
Current datasets report Astound Broadband cable coverage ranging from approximately 44.1% to 58.07%, depending on the source.
Current FCC-derived ZIP data reports Sonic fiber availability at approximately 14.22%.
Current ZIP-level sources identify AT&T fiber, T-Mobile 5G, Verizon 5G, XNET, Etheric, Unwired and other providers in 94107.
These percentages are treated as coverage indicators and dataset outputs, not live provider guarantees.

Research limitation: ZIP codes are postal geographies rather than broadband service boundaries. Provider datasets can use different update dates, geographic units and coverage methodologies. This is particularly relevant in 94107 because the ZIP contains older residential blocks, industrial-to-residential redevelopment and newer multifamily construction. Provider address checkers remain the final authority for a specific property.

94107 internet provider FAQ

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

What internet providers serve ZIP code 94107?

Current ZIP-level evidence identifies Xfinity, Astound Broadband, Sonic, AT&T, T-Mobile, Verizon and additional fixed-wireless and satellite providers in the 94107 market. Xfinity has the broadest reported cable footprint, while Astound adds a substantial second cable network and Sonic and AT&T provide fiber in smaller portions of the ZIP.

Does Xfinity serve 94107?

Yes. Current ZIP-level sources report Xfinity cable coverage at approximately 99.7% to 99.68% of 94107. Some locations also have Xfinity fiber-class service. The ZIP-wide figure should not be interpreted as a guarantee for every apartment or unit.

Does Astound Broadband serve 94107?

Yes. Astound appears in current ZIP-level broadband data for 94107. Coverage estimates vary, with current sources reporting approximately 44.1% and 58.07%. The consistent finding is that Astound has a substantial but incomplete cable footprint.

Is Sonic Fiber available in 94107?

Yes, but current ZIP-level data reports a much smaller footprint than Xfinity's cable network. One current dataset reports Sonic fiber at approximately 14.22% of 94107. Sonic's San Francisco network can support multi-gigabit service where the fiber reaches the property.

Is AT&T Fiber available in 94107?

AT&T has both fiber and older broadband technologies in the San Francisco market. Current 94107 data reports AT&T fiber in a smaller portion of the ZIP while broader AT&T service categories cover more locations. The exact address determines which technology is available.

Is T-Mobile 5G Home Internet available in 94107?

Current ZIP-level provider data reports T-Mobile 5G home internet in 94107, with one current dataset reporting approximately 59% availability. Fixed-wireless eligibility can depend on the exact address, network capacity and wireless conditions.

Is Verizon 5G Home Internet available in 94107?

Verizon 5G Home Internet appears in current 94107 provider data. Coverage estimates vary substantially by dataset, so Verizon's address-level checker should be used before treating the service as available at a particular property.

Can two nearby buildings in 94107 have different providers?

Yes. Cable and fiber networks can have different building footprints, while fixed-wireless eligibility can depend on capacity and signal conditions. This matters in 94107 because Potrero Hill, Dogpatch, Mission Bay and eastern SoMa contain different building types and development patterns.

Why does 94107 have both older and newer broadband infrastructure?

The ZIP combines established residential areas with portions of the Central Waterfront, Dogpatch and Mission Bay development areas. San Francisco planning documents describe continuing housing and mixed-use development alongside historic industrial and PDR uses. As a result, buildings in the same ZIP can have different ages, internal wiring and telecom arrangements.

Is the fastest advertised speed necessarily the best connection?

Not necessarily. Download speed is only one measurement. Upload capacity, latency, congestion, equipment, installation, regular pricing and the physical network reaching the property can materially change the practical value of a connection.

Why do 94107 coverage percentages differ between sources?

Broadband datasets can use different update dates, geographic units, provider records and methods for converting network availability into ZIP-level percentages. For 94107, the sources consistently identify Xfinity as the broadest cable network and Astound as a substantial secondary cable provider, while the reported fiber and wireless percentages vary more between datasets.

Why does this page use ZIP-level data instead of claiming exact coverage?

ZIP-level data is useful for identifying the broadband market around 94107, but provider networks do not follow postal boundaries exactly. Treating a ZIP percentage as proof of service at every address would overstate what the data establishes. The most precise answer comes from checking the provider against the exact street address 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, condominiums, mixed-use developments and individual properties may have different network infrastructure. Always confirm service, technology, speed, equipment requirements and current pricing directly with the provider before ordering.
