Free United States of America Proxy List HTTP, HTTPS, SOCKS4 & SOCKS5

The US list is the deepest national pool on Databay short of Indonesia's (490 live entries at the June 2026 snapshot) and the most balanced: roughly 40% SOCKS4, 35% SOCKS5, 25% HTTP. Three-quarters of rows tested elite at header level, nearly 80% were HTTPS-capable, and median response ran about 1.5 seconds. None of that is surprising. American entities hold the largest share of routable IPv4 space by a wide margin, and the US hosting and cloud industry is the world's biggest, so there is simply more reachable address space for open services to appear in. Port 4145 led the count, followed by the standard 80 and 1080; security researchers have repeatedly tied that port to SOCKS4 services running on compromised MikroTik routers. Depth has a practical consequence: the US list can absorb spot-check workloads that would exhaust a 20-proxy country in minutes.

The catch with US verification work is that country-level is often not enough. Sales tax, age gates, sports blackouts, lottery and gambling rules, and increasingly state privacy laws (California's CCPA banners, for one) all vary below the national level, and a free country pool gives you no state control. What a US exit reliably delivers: US-version SERPs and ad loads, national retail pricing and dynamic-pricing checks on airlines and hotels, US streaming catalog presence at country granularity, and confirming your own geo-targeting fires the US experience. For state-accurate work, look up each row's geolocation yourself and cherry-pick, or accept that you need a paid pool with state targeting.
