ZIP-specific overview

What 78745 tells you — and what it does not

ZIP code 78745 covers a large portion of South Austin and includes addresses associated with Austin as well as Sunset Valley. The ZIP is crossed by major local corridors including South Congress Avenue, Brodie Lane and William Cannon Drive, giving it a mix of established residential, multifamily and commercial properties.

That geography matters for broadband research because 78745 is not a single housing type or a single network footprint. A detached home, apartment building and commercial or mixed-use property can have different service options even when they share the same ZIP code.

The Austin market has several overlapping wired broadband networks. Google Fiber and AT&T operate fiber networks in the Austin market, while Spectrum and Astound provide cable and fiber-powered services in parts of the market. Provider availability remains dependent on the service address.

There is also direct provider evidence inside 78745. AT&T has a retail location at 801 East William Cannon Drive that lists home internet, and Spectrum has a store at 5400 Brodie Lane in 78745. These locations establish local provider presence; they do not prove that every nearby property can order the same residential service.

Local research conclusion: 78745 is a useful ZIP for identifying the providers that deserve an address check, but the meaningful broadband comparison begins only after the exact property, technology and available plan are confirmed.

Providers worth checking in 78745

The providers below are supported by Austin-market or ZIP-specific evidence. Their inclusion does not mean that every 78745 address can order the same technology or plan.

Google Fiber

Fiber
Address check

Google Fiber currently serves the Austin market and provides an address-based availability check. Its Austin service page lists symmetrical fiber plans, including multi-gigabit tiers. Those Austin-market offerings should not be converted into a claim that every 78745 property receives the same service.

ZIP evidence

AT&T's Austin-area service information identifies Sunset Valley with ZIP codes including 78745 and lists fiber service up to 5 GIG. AT&T also states that internet availability depends on the customer's address. A 78745 ZIP match therefore supports investigation, not automatic eligibility.

Local availability analysis

Why 78745 should be checked address by address

78745 combines a broad South Austin geography with several overlapping broadband networks. The ZIP boundary is not a substitute for a serviceability check.

Fiber availability

Google Fiber and AT&T both operate fiber networks in the Austin market. AT&T's own Austin-area information specifically associates 78745 with its fiber service area, while Google Fiber requires an address check. Neither fact establishes fiber at every property.

Cable availability

Spectrum and Astound are both relevant to an Austin broadband comparison. Their networks and technologies can vary by location, so the actual property should be checked before assigning a cable or fiber-powered connection to an address.

5G home internet

T-Mobile and Verizon both identify Austin as a market for 5G home internet. Fixed-wireless eligibility can depend on the service address, signal conditions and available network capacity.

Apartment buildings

Multifamily properties can have building-specific wiring, preferred providers, bulk agreements or installation restrictions. A provider serving nearby houses may not offer the same installation path inside an apartment building.

Sunset Valley boundary

78745 includes addresses associated with Sunset Valley as well as Austin. A municipal boundary does not determine broadband availability, so properties near the boundary should still be checked by complete address.

FCC location data

The FCC National Broadband Map allows consumers to search an address and review reported fixed broadband providers, technologies and maximum advertised speeds associated with that location.

Technology in 78745

Compare the connection type, not just the speed number

78745 is in an Austin market with fiber, cable and fixed wireless options. The connection type can affect upload capability, latency, equipment and how performance behaves under network load.

Fiber internet

Google Fiber and AT&T both market fiber service in Austin. Fiber plans can provide symmetrical or substantially higher upload performance than many cable configurations, but the available network and tier must be confirmed at the 78745 property.

Cable internet

Spectrum and Astound are relevant cable or fiber-powered options in the Austin market. For an actual 78745 address, compare both download and upload speeds along with the regular monthly price and equipment terms.

Fixed wireless / 5G

T-Mobile and Verizon offer fixed-wireless home internet in the Austin market. Wireless service does not require a wired last-mile connection to the home, but eligibility and performance depend on the actual location and network conditions.

Satellite

Satellite internet remains a separate connectivity option for properties where terrestrial services are unavailable or unsuitable. Compare latency, equipment, data policies, installation and total cost with wired and fixed-wireless alternatives.

Address-level verification

Check the actual property before choosing a provider

The FCC National Broadband Map can be used to examine reported fixed broadband providers, technologies and advertised speeds associated with an individual location.

Provider address checkers should then be used as the final purchasing check. Provider systems determine what can currently be ordered and may contain information that differs from public broadband datasets.

78745 FAQ

Questions about internet providers in 78745

These answers distinguish ZIP-specific evidence from actual address-level availability.

Which internet providers should I check in 78745?
Start by checking Google Fiber, AT&T Fiber, Spectrum and Astound Broadband. T-Mobile and Verizon 5G Home Internet are also relevant Austin-market options where the service address qualifies. These providers are options to investigate, not proof that every 78745 property can order each service.
Is Google Fiber available in 78745?
Google Fiber currently serves the Austin market and provides an address-based availability checker. Use the complete 78745 property address to determine whether Google Fiber is actually available there.
Is AT&T Fiber available in 78745?
AT&T's Austin-area service information identifies Sunset Valley and ZIP code 78745 with fiber service. AT&T still requires an address check because availability can differ between individual properties.
Is Spectrum available in 78745?
Spectrum operates in Austin and has an official store at 5400 Brodie Lane, Suite 915, Austin, TX 78745. That establishes a Spectrum location inside the ZIP, but the residential address checker should be used to confirm serviceability.
Does Astound Broadband serve 78745?
Astound currently lists Austin among its Texas service areas and offers an address-based availability check. Use the exact 78745 address to determine whether Astound serves the property and which technology is offered.
Is T-Mobile Home Internet available in 78745?
T-Mobile currently states that 5G Home Internet is available in Austin. T-Mobile also states that eligibility is determined by the service address and network capacity, so Austin-wide availability does not establish eligibility at every 78745 property.
Is Verizon 5G Home Internet available in 78745?
Verizon currently lists Austin among its 5G Home Internet markets. Verizon says availability depends on the home address, so enter the complete 78745 address into its availability checker before treating the service as available.
Does internet availability vary within 78745?
Yes. Broadband infrastructure and provider serviceability are determined at locations rather than simply by postal boundaries. Nearby homes or apartment buildings can have different provider and technology options.
What is the fastest internet available in 78745?
The answer depends on the property. Austin has multiple fiber providers and multi-gigabit plans are marketed in the Austin market, but the highest advertised Austin speed should not be presented as available throughout 78745. Check the exact address before naming a specific tier.
Should I compare cable and fiber by download speed?
No. Compare the actual download and upload speeds, technology, regular price, promotional terms, equipment charges and installation costs shown for your address.
What should apartment residents in 78745 check?
Ask property management whether the building has a preferred provider, bulk internet agreement, included service or installation restrictions. A provider available at a nearby single-family property may not be available through the same installation path inside an apartment building.
Where can I verify providers for my exact address?
Start with the FCC National Broadband Map, then use the provider's own address checker. The FCC map provides location-level reported broadband information, while the provider determines what it can currently offer and order at the property.

Provider prices and promotional offers are intentionally not treated as permanent ZIP-specific facts. Pricing, equipment charges and promotions can change frequently and may depend on the service address or customer eligibility.

Austin-wide coverage estimates are not used as definitive evidence of service at an individual 78745 address. Provider-market information is used to identify networks worth checking, while address-level availability is left to the FCC location record and provider serviceability systems.

Availability and pricing disclosure: Internet availability, advertised speeds, plan prices, promotional offers, equipment charges, installation fees and network coverage can change. ZIP-level information is useful for identifying potential providers but does not guarantee service at an individual address. Confirm final availability, speed, pricing and terms directly with the provider before ordering.
