California Mobile IPs for Marketers: Check From LA

California is the largest state market in the United States, home to the entertainment industry and to the strictest state privacy rules, and a campaign or a launch that works in New York does not necessarily work in Los Angeles. A California line from Stateside Proxies is a dedicated AT&T, T-Mobile or Verizon carrier line in our Los Angeles hardware, used by you alone, that puts your browser inside the Californian audience. This page explains what a California address tells a website, why our Californian hardware is in Los Angeles, what teams check from it, and what it costs.

What a California address tells a website

That the visitor is on a US mobile carrier, in California, on a phone. An IP lookup names the carrier, reads cellular, and places the address in California; the city field reads Los Angeles most consistently on T-Mobile, Los Angeles or another large Californian city on AT&T, and possibly another Californian city on Verizon. For ad targeting, the California consent notice, tax and state-level checks, the state is what counts and it is reliable on all three carriers.

Why Los Angeles

Los Angeles has a very large population, 4G and 5G from all three carriers, and the production side of the entertainment industry, so the platforms most tuned to American social and entertainment traffic expect a lot of it from here. The clock is Pacific time, three hours behind New York, which matters for campaigns and checks timed to West Coast daytime. We run no hardware in San Francisco or San Diego; a Los Angeles line reads as California for every state-level purpose.

What teams check from a California line

Ad verification for campaigns bought for Los Angeles and for California, including entertainment and streaming campaigns. Geo QA of US sites for a Californian visitor, above all the California-specific privacy notice and opt-out links that a visitor from any other state never sees. Competitor monitoring of West Coast prices, offers and inventory. Local search results for Los Angeles queries. Research on public Californian data within each site's terms.

Move the line here last if a national check has already run elsewhere.

The line, plainly

One SIM in one device, a USB modem, a router or an Android phone chosen at checkout, used by one customer. HTTP(S) and SOCKS5 with UDP, a VLESS link for a whole device on server-based lines, unlimited data, rotation on demand without limit, and an address that holds as long as you want it. 4G up to 25 Mbps download and 5G up to 50 Mbps; eligible 5G lines take the 5G+ add-on for a 70 Mbps+ average. Free moves to our other seven metros with the remaining time kept. Immediate activation; a person on support at any hour.

Carrier, device and clock for California work

T-Mobile when the city reading should be Los Angeles and for the fastest 5G; AT&T for a steady, conservative address; Verizon for the strongest consumer reputation where a California reading is enough. A modem or router for browser and screenshot work; a phone for app checks. Stock per carrier and device is shown at checkout at base.statesideproxies.com. Set the browser profile to America/Los_Angeles, Pacific time, and run checks in Los Angeles daytime.
