* This operator reports several technologies to the FCC nationally, and the federal data does not break that down by city, so we cannot tell you which one reaches a specific street in San Francisco. Read the percentage as the whole company, not the brand. A national carrier files its fiber, its cable, its copper and its fixed wireless under one identifier, so a row marked Mixed can be counting a home wireless service even where the brand most people know is a fiber one. We mark a technology plainly only when at least 80% of what that operator reports nationally sits on it. Satellite providers are shown last and marked “nationwide” because they cover essentially every address in the country, so their coverage figure tells you nothing about San Francisco specifically.

How San Francisco compares
Of the 1,606 places in California where at least one company reports service, San Francisco ranks 6 for the number of operators reporting and 2 for the number of those that report any fiber. The typical California place has 9 reporting and 5 with fiber; San Francisco has 17 and 12. Nationally that puts it in the best served 1% of places.
More companies is not the same as more choice. An operator counts here if it reports service anywhere in the place, even on one street, so these totals run far above the number of companies that can actually reach a given house. Checked across Ohio, 99% of places have three or more operators reporting some fiber, while the block level study finds 27.9% of US homes with no fiber at all. Both are true and they measure different things. Read the rank as a comparison between places, never as a count of what you can buy, and read the coverage column above for that. A census place can also be a large city or a village of two hundred, so this is a rank among places of every size.
What speeds are available across California
This is state-level data, not San Francisco data. The FCC does not publish speed availability below county level, so we will not pretend to have a figure for San Francisco. Treat the table below as the backdrop for California as a whole.
| Technology | 25/3 Mbps | 100/20 Mbps | 250/25 Mbps | 1 Gbps / 100 Mbps |
|---|---|---|---|---|
| Fiber | 40% | 40% | 40% | 40% |
| Cable | 90% | 90% | 90% | 34% |
| Fixed wireless | 88% | 73% | 41% | 9% |
| Any technology | 100% | 100% | 100% | 66% |

How to read these numbers
A provider at 90% is a realistic option for almost everyone in San Francisco. A provider at 5% has built out a handful of streets and possibly including yours, possibly not. Neither figure is a promise, because providers report their own coverage to the FCC and the data is known to overstate it.
If a provider tells you they cannot serve your address, they are right and the map is wrong. We would rather say that plainly than pretend to a precision this data does not have.
