## What broadband technology do San Diego homes use?

Fiber reaches 40.2% of San Diego's residential units, 36th of the 45 cities we track and below the 62.2% median. Cable covers 89.7%, less than in most of our cities. Copper DSL remains at 63.8%. Gigabit service (1,000/100 Mbps) is available to 68.2% of units. Access type matters for testing: fiber and cable homes usually get their own public IPv4 address, while fixed wireless users often share one.

*FCC National Broadband Map, December 31, 2025 data; any provider, residential units*

| Access type in San Diego | Residential units covered | Rank among the 45 cities |
| --- | --- | --- |

## How do I target a San Diego ISP in my proxy username?

Start from the city: `USERNAME-country-us-state-ca-city-san_diego` asks for any home IP in San Diego. Then add the ASN of the provider you need:

- `USERNAME-country-us-state-ca-city-san_diego-asn-7018`: AT&T in San Diego.
- `USERNAME-country-us-state-ca-city-san_diego-asn-22773`: Cox in San Diego.
- `USERNAME-country-us-state-ca-city-san_diego-asn-20001`: Spectrum in San Diego.
- `USERNAME-country-us-zip-92101-asn-7018`: AT&T in ZIP 92101 (East Village).
- `USERNAME-country-us-state-ca-city-san_diego-asn-22773-session-sandie1-ttl-20`: one Cox IP kept for up to 20 minutes.

Use `gw.broadbandproxies.com`, port 7777 for HTTP and HTTPS or 7778 for SOCKS5. If a request finds no IP online, drop the ZIP first, then the city, and keep the ASN.

## San Diego: two cable networks now owned by one company

San Diego is split between Cox (48.7% of residential units) and Spectrum (46.1%) in the FCC data. Since Charter completed its Cox deal on August 19, 2026, both cable networks belong to the same group, though they still route on different ASNs: AS22773 for Cox and AS20001 for the former Time Warner Cable side. AT&T reports 84.9%, the widest wired network in the city.

## Which CA rules matter for checks from San Diego?

California has a comprehensive privacy law, the California Consumer Privacy Act, as amended by the CPRA (CPRA amendments in effect since January 1, 2023). It governs how businesses treat residents' data; it is not a rule about proxies, and it does not make a check from a San Diego IP lawful or unlawful. Prices shown to San Diego shoppers may add sales tax at checkout: the combined state and local rate is 7.75% since 2026-10-01, so compare pre-tax prices when you check retail pages from a San Diego IP. San Diego is on Pacific Time: schedule checks of time-limited offers and local ads in that zone. Whatever the city, our [acceptable use policy](https://broadbandproxies.com/acceptable-use/) applies; blocked targets: Banking, government and payment-portal sites, plus SMTP (email-sending) ports 25, 465 and 587.

The rest of the balance is not paid back, except where the law requires it. No identity documents are asked for.

### Is San Diego a fiber city?

Not yet. The FCC map shows fiber available to 40.2% of San Diego's residential units (December 31, 2025), 36th of our 45 cities, against 89.7% for cable. Fiber at 1,000/100 Mbps or more reaches 37.7%.

Yes. ZIP targeting works in the United States on every plan: `USERNAME-country-us-zip-92101` asks for East Village, and `zip-92109` for Pacific Beach. You can add an ASN, but a ZIP-plus-ISP request matches fewer homes, so test it before scaling.
