Concord in California
Concord is wired twice over by cable. Xfinity reports service at 98.7% of the city's homes and businesses and Astound at 97.6%, so 96.6% can choose between at least two wired providers at 100/20 Mbps, against 49.9% across California. Fiber is the thinner layer: AT&T and Sonic bring it to 37.0%1 of locations, up from 19.4%2 in 2022.
Two cable companies at the same locations
Concord has two cable companies whose networks overlap almost completely: Xfinity reports cable or fiber service at 98.7% of the city's 33,852 homes and businesses, and Astound at 97.6%. Cable of some kind is reported at 99.9% of locations, a share that ranks tied for 3rd highest1 among the 343 cities of 100,000 or more.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (Viasat, Starlink, HughesNet) report service at nearly every location and are left out of the table.
The table counts every location inside the city limits as drawn for the 2020 Census, as reported to the FCC as of June 30, 2026 (file revision of November 10, 2026). "Reported" means the provider says it serves the location or could connect it within ten business days in a standard installation; anyone can challenge a claim on the FCC National Broadband Map. Satellite providers report every location and appear only for completeness.
Choice is wide, and it comes from cable
Because both cable networks advertise 100/20 Mbps or more nearly everywhere they reach, 96.6% of Concord's locations have at least two wired providers at that speed, the 12th highest share among large cities. Statewide the figure is 49.9%, nationally 55.6%. A third wired provider at that speed is reported at 42.9%1 of locations, up from 27.8%2 in June 2022.

Antioch, also in Contra Costa County, has a similar fiber share, 37.7%, but only one cable network, Xfinity's. There only 44.1% of its locations have two wired choices at 100/20 Mbps, and 55.5%1 have just one.

The single-wire locations in Concord are small. Exactly one wired provider offers 100/20 Mbps at 3.3% of locations (1,109 of them); Xfinity is that provider at 2.2% of the city's locations and Astound at 1.1%. No wired provider reaches 100/20 Mbps at 391 locations, which still have fixed wireless at that speed.
Fiber: two networks, just over a third of the city
Fiber is where Concord trails. It is reported at 37.0% of locations, a share that ranks tied for 53rd lowest among large cities, compared with 47.8% statewide. AT&T reports fiber at 25.7% of locations, and Sonic, which reported no Concord locations in June 2022, now reports 25.1%, with an advertised maximum of 10 Gbps. Their footprints partly coincide: 14.8%1 of locations have two or more fiber providers.

| Vallejo | 42.9% |
| Antioch | 37.7% |
| Concord | 37.0% |
Richmond, Oakland and Berkeley have far more fiber than Concord: 78.2%, 90.1% and 91.6% of locations respectively. Most of Concord's fiber growth happened before the end of 2025; the share rose by 0.5 percentage points1 in the six months to June 30, 2026.
Gigabit uploads arrived over cable
The speed numbers changed more than the provider list. In June 2022, gigabit service with uploads of at least 100 Mbps (the FCC's 1,000/100 tier) was advertised at 19.4% of locations, the same share as fiber. By June 2026 it was 93.3%, a rise of +73.9 percentage points, while fiber reached only 37.0%. The difference is cable: at most locations without fiber, the fastest advertised plan is now a cable plan with 100 Mbps or more upstream. The fastest advertised download is 2 Gbps or more at 93.1%1 of locations, up from 13.8%2.

DSL over copper telephone lines shrank at the same time. DSL is now reported at 68.9% of locations, down from 72.2%2 in 2022, and AT&T offers 100/20 Mbps at only 35.9%1 of locations. All speeds here are advertised maximums, not measurements.
A local wireless network beside the carriers
Fixed wireless covers Concord almost as completely as cable. Unwired Ltd reports licensed fixed wireless at 96.6% of locations, all of them at 100/20 Mbps or more, with an advertised maximum of 250 Mbps. Verizon reports home internet at 85.9% of locations but 100/20 Mbps at 33.2%; T-Mobile reports 73.2%, with 100/20 at 23.3%1.

| Fiber | 37.0% | 47.8% |
| Cable | 99.9% | 90.5% |
| DSL (copper) | 68.9% | 43.7% |
| Licensed fixed wireless (incl. 5G home) | 99.7% | 88.1% |
| Unlicensed fixed wireless | 0.0% | 35.3% |
Older data describe the wireless layer differently. In June 2022, unlicensed fixed wireless was reported at 96.8% of locations and licensed fixed wireless at 100/20 Mbps at 3.3%2; in June 2026 the figures are 0.0% and 98.5%1. Readers comparing older maps should keep that in mind. Wireless capacity is shared on each tower sector, so the FCC figures show where service is reported, not where every home could sign up at once.
What Concord households subscribe to
The Census Bureau's surveys count households, not locations, and carry sampling error. In the 2020–2024 five-year estimates, 95.1% of Concord households had a broadband subscription (margin of error ±1.0 percentage points) and 82.3% subscribed to cable, fiber or DSL (±1.4 percentage points4). The single-year 2025 survey puts households relying only on a cellular data plan at 14.7% (±3.9 percentage points5).

The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
