Undetectable.io for Ad Verification Teams on a Stateside Line

Undetectable.io is an antidetect browser: it keeps separate browser profiles, each with its own fingerprint, cookies and proxy, so that each profile looks to a website like a different device. For a verification or research team that is exactly the right tool, because a profile per US market, each on its own Stateside Proxies line, gives every market its own consistent visitor and keeps the team's own browsing out of the picture. This guide explains the setup in plain terms: where the line goes, which three settings must match the metro, how to confirm the profile before using it, and how a team shares profiles without stepping on each other.

Why a profile browser rather than a plain proxy setting

A proxy typed into an ordinary browser changes the address but leaves everything else as yours: your time zone, your language, your cookies and history. A site comparing those signals sees a visitor whose network says Chicago and whose browser says Lisbon. A profile browser gives each market its own browser with its own settings and nothing carried over from your desk, so the visitor is consistent from the first page load.

What you need from the dashboard

Sign in at base.statesideproxies.com and open the line. The card shows a host, an HTTP port, a SOCKS5 port, a username and a password, plus the metro the line sits in. Undetectable.io accepts both HTTP and SOCKS5; use SOCKS5, which carries all traffic and keeps name lookups inside the line. The rotation link on the card stays outside the profile; it is only for changing the address.

Setting up a market profile

Save the line once in Undetectable.io's proxy manager, then attach it to a profile named for the market. When a line moves to another metro, one edit in the manager updates every profile that uses it.

1. Open the proxy manager, add a SOCKS5 entry with the host, SOCKS5 port, username and password, and name it after the metro, for example Chicago market.
2. Press Check and confirm United States, the carrier and a city in the metro's state.
3. Create a new profile named for the market, choose a Windows or Android fingerprint as your audience would have, and attach the saved proxy.
4. Set time zone to follow the proxy or by hand to the metro: Central for Chicago and Houston, Eastern for New York, Boston, Miami and North Carolina, Mountain for Phoenix, Pacific for Los Angeles.
5. Set language to en-US and geolocation to follow the proxy, save, and launch.

The check before any verification

Inside the launched profile, open an IP lookup page: the organisation should be the carrier, the type cellular or mobile, the location the metro or its state. Open a WebRTC test and confirm no address other than the carrier's appears. Compare the profile's clock with the metro's. Screenshot the lookup; it opens every report and proves where the browser was.

Sharing profiles across a team

Undetectable.io can keep profiles in the cloud so colleagues open the same market profile from their own machines. One profile per market, one line per profile, and a naming convention that puts the metro first keep the team from mixing markets. Rotate the line between sessions, not during one, and update the saved proxy once after a free move to a new metro, then update the profile's time zone to match.

• One profile per market, named metro first.
• One line per profile; related markets may share a line, unrelated ones should not.
• Rotate between sessions, never mid-session.
• After a metro move: edit the saved proxy, then the time zone.

What usually goes wrong

Most problems with a verification profile come from small habits rather than from the setup. A colleague opens the market profile while connected through their own company VPN, and the first screenshots of the day show the wrong network. Someone edits the time zone by hand after a move and forgets to change it back. Two people open the same profile at the same moment and lose each other's cookies, which resets any retargeting sequence that was being followed. An agreed routine avoids all three: one person per profile at a time, the VPN off, and an IP lookup screenshot before anything else is recorded. Keep the routine written in the shared folder, where new colleagues will see it on their first day. It takes a minute to read and saves a morning's rework.
