What San Francisco residential proxies do
A San Francisco residential proxy sends your requests through a real home internet connection in the San Francisco metro. The sites you visit see an ordinary local visitor, so the prices, ads, search results and catalog availability you receive are the ones a Bay Area user would normally get. Nefo lets you choose that exit by adding a city token to the proxy username.
San Francisco is described as a competitive Bay Area market. That is where advertisers and retailers are likely to be most active, so ad verification and local search checks from a Bay Area exit are the typical starting point.
Credentials are free and you pay only for traffic. Residential bandwidth starts at $4.50 for 5 GB ($0.90/GB), falls to $0.53/GB at 10 TB, and never expires, so a small test of the market costs little. The full price list shows every package.
How to target San Francisco with a city token
Add the city token to your username, then authenticate to the gateway gw.nefo.net:
USERNAME-country-us-city-san_francisco- Use HTTP port 9000 for rotating IPs, which take a new address on every request.
- Use port 10000 for sticky sessions, which hold one IP from 1 minute up to 24 hours.
- SOCKS5 and HTTPS are also supported, so the same token works in browsers, scrapers and command-line tools.
- Build ready-made strings in the dashboard generator; the full token syntax is in the docs.
Choose rotating for broad single-request sampling, such as a batch of search snapshots or product pages. Choose sticky when one task spans several steps on the same site and the IP must not change midway. See how sticky sessions work.
What San Francisco targeting covers and what it does not
Targeting is city-level, not ZIP or neighborhood level. You reliably reach residential IPs within the San Francisco metro, but Nefo does not guarantee a specific neighborhood or suburb or postal code. For most localized monitoring that is enough, because the goal is to see the Bay Area version of a page rather than one street.
If you need a different level of precision, the US city-targeted proxies page explains the options, and US residential proxies covers country-level use.
Legitimate uses for San Francisco proxies
City-level residential IPs let you view the public web the way a San Francisco shopper or searcher would across the Bay Area market. Keep usage lawful and limited to public data.
- Local price monitoring across San Francisco retail and marketplace listings.
- Verifying geo-targeted ads and promotions served to Bay Area audiences.
- Localized SEO and SERP checks for the San Francisco metro.
- Market research on region-specific catalogs and availability.
Follow each site's terms of service and applicable law, and see the acceptable use policy. Proxies are not a way around logins you are not entitled to use.
Test a San Francisco proxy from the command line
A quick way to confirm the exit is in the right market is a single request through the gateway. Replace the placeholders with your own credentials:
curl -x http://USERNAME-country-us-city-san_francisco:[email protected]:9000 https://example.comRun it a few times on port 9000 and each call should come from a different residential IP in the San Francisco metro. Switch to port 10000 and the IP stays fixed for the session length you set. The same string works in Python, Node and browser automation; see Python Requests and Puppeteer for code samples.
Because bandwidth is billed per GB and never expires, a short San Francisco test run costs a few cents of your balance, and anything unused stays available for the next project. Unused rotating residential bandwidth is also refundable within 7 days at the per-GB rate paid, minus processing fees, as described in the refund policy.
Compare San Francisco with other US cities
Because only the token changes, you can run the same job against several markets and compare the output. Cities that pair well with San Francisco:
- Los Angeles proxies for a second market to compare against.
- Seattle proxies for a second market to compare against.
- Denver proxies for a second market to compare against.
The US proxies hub lists all twelve city pages, and United States proxies covers country-level residential, datacenter and static options.
