The two checks our team runs before a customer gets a line, open to everyone to use. No sign-up, nothing stored.
What IP am I on? Your carrier, ASN and city, time-zone match and WebRTC leak, seen at once.
Free toolProxy checkerFor one proxy or a whole list (HTTP, HTTPS, SOCKS4, SOCKS5), see the exit IP, location, ISP and latency of each line, then export the ones that work.

To test browser fingerprinting, bot detection, DNS and WebRTC leaks, we refer customers to IPFighter's free suite, which works well with a USAProx line:
IP score & lookup ↗ Browser fingerprint ↗ Bot detection ↗ DNS leak test ↗ WebRTC leak test ↗ IPFighter proxy checker ↗
What antidetect browser should I use with a US mobile IP? Undetectable.io is our recommendation. Set the profile's timezone and language to match the US city of your USAProx proxy and paste the HTTP or SOCKS5 details. GoLogin also works well.
Windows and macOS, a free starting plan, and profiles both local and in the cloud. Give each profile its own USAProx line.
Get Undetectable.io ↗A free plan covering 3 profiles, on Windows, macOS and Linux as well as phone apps. Put a USAProx line in as host:port:user:pass.
Get GoLogin ↗Partner links. Our lines work with any antidetect browser that can use an HTTP or SOCKS5 proxy, and these are our two recommended picks.
