Ad verification is the practice of independently checking that ads, affiliate offers, and landing pages render correctly, comply with policy, and are not swapped, cloaked, or geo-restricted for the audience that should see them. Doing it credibly requires viewing the web from a real consumer connection — which is why Proxy4G serves genuine carrier IPs on AT&T, Verizon, T-Mobile, Three, EE, Free Mobile, Orange, Vodafone, Jio 5G and 38 more across 18 countries, each carrying a 100% trust score.
Why do ad checks need a mobile IP instead of a datacenter one?
Ad servers, affiliate networks, and cloaking scripts profile the visitor before deciding what to show. A datacenter IP is trivially identified — its ASN belongs to a hosting provider, it is on public blocklists, and many ad platforms simply serve a clean, compliant page to it while showing the real (sometimes non-compliant) creative to consumers. That defeats the entire point of verification.
A Proxy4G mobile IP is indistinguishable from a phone on a real network. Carriers route subscribers through Carrier-Grade NAT (RFC 6598), so thousands of legitimate users share each public IP. That shared, high-reputation address is exactly what makes the IP trusted — and exactly what makes cloaking systems treat your verification request as a real lead. To understand the trust gap in detail, see mobile vs residential vs datacenter proxies.

How does geo-targeting let you catch cloaking and fraud?
Most ad and affiliate fraud is geo-conditional: an offer shows a compliant page in the US but a scam funnel in Brazil, or a competitor runs a trademark-bidding ad that only fires for searchers in France. To prove it, you must request the page from that exact country and carrier — not from a US datacenter pretending to be French.
With Proxy4G you select the country (and often the specific carrier) and see precisely what a local mobile user sees:
- Creative swaps — the ad shown to your bot differs from the one shown to consumers.
- Landing-page cloaking — a clean page for reviewers, a money page for traffic.
- Geo / device gating — offers that only fire on mobile carriers in target regions.
- Affiliate compliance — partners running prohibited claims, brand bidding, or incentivized traffic.
Because every Proxy4G IP is a real carrier address, the verification environment matches your real audience, so a difference between what you see and what was promised is real evidence — not a datacenter artifact.
Mobile vs residential vs datacenter for ad verification
All three can return a page, but only one consistently sees what consumers see. The table below compares them on the signals that actually decide whether a cloaker reveals its real creative to you.
Which proxy type sees the real ad?
| Capability | 4G/5G Mobile | Residential | Datacenter |
|---|---|---|---|
| Carrier-grade trust (CGNAT) | Yes — shared carrier IP | Partial | No |
| Bypasses cloaking that targets hosting ASNs | Yes | Often | No |
| True mobile-carrier creatives | Yes — physical SIM | No (fixed line) | No |
| Per-country + per-carrier targeting | 18 countries, 43 carriers | Varies | Varies |
| Rotate IP to re-sample placements | On demand or 1–60 min | Varies | Yes |
Mobile is the only option that reproduces the exact carrier conditions a phone-using consumer experiences.
Which countries and carriers should I verify from?
Pick the markets where your campaigns or affiliates actually run. Proxy4G covers United States (AT&T, T-Mobile, Verizon, T-Mobile 5G), United Kingdom (Three, EE, Three 5G), France (Free Mobile, SFR, Orange, Bouygues), Germany (O2, Vodafone 5G), Spain (Movistar, Orange, DIGI), Italy, Netherlands, Poland, Romania, Czech Republic, Lithuania, Latvia, Austria, Turkey, Thailand, Brazil, Bangladesh, and India (Vodafone, Jio 5G).
For fraud-heavy verticals, sampling multiple carriers in one country matters: a cloaker may whitelist one network and gate another, so checking, say, both Free Mobile and Orange in France surfaces inconsistencies a single carrier would miss.

Confirm the exit IP and country before you verify
# Dedicated US carrier exit — check what the ad server will see
curl -x http://USER:PASS@HOST:PORT https://api.ipify.org
# Confirm geolocation matches your target market
curl -x http://USER:PASS@HOST:PORT https://ipinfo.io/json
# Force a fresh IP to re-sample the same placement (Dedicated rotate link)

Choose by cadence and isolation. Dedicated proxies (from $27/mo) give you an exclusive port and on-demand rotation — instantly via the dashboard or reset link, or automatically every 1–60 minutes. That control matters when you need to re-request a placement under a fresh IP at a precise moment, or keep a stable session while you screenshot and document a violation.
For broad, automated spot checks across many offers, rotating shared proxies (from $10.80/mo) auto-rotate every 5 minutes and cost far less per market. Many teams run dedicated IPs for evidence-grade documentation and shared IPs for volume sweeps. Both plans deliver real carrier IPs at a 100% trust score, with HTTP/HTTPS/SOCKS5 support. Credentials (HOST, PORT, user, pass) arrive by email within minutes of crypto payment.
Frequently Asked Questions
Datacenter IPs advertise a hosting ASN and sit on public blocklists, so ad servers and cloaking scripts often serve them a clean, compliant page while showing the real creative to consumers. That makes any "verification" from a datacenter IP unreliable. Proxy4G mobile IPs are genuine carrier addresses behind CGNAT with a 100% trust score, so you see the same ad a real phone user sees.
Cloaking shows different content based on the visitor's IP reputation, geo, and device. Because Proxy4G routes through real carriers in 18 countries, the page decides you are a genuine local mobile user and reveals its true creative and landing page. Comparing that to what was promised — or to what a datacenter IP receives — exposes the swap. Rotating the IP lets you re-sample to confirm the pattern.
All 18 in inventory: the United States, United Kingdom, France, Germany, Italy, Spain, Netherlands, Czech Republic, Poland, Romania, India, Lithuania, Thailand, Brazil, Bangladesh, Turkey, Latvia, and Austria — across 43 carriers, including 5G on select networks.

Yes. Cloakers sometimes whitelist one network and gate another, so sampling several carriers in one country surfaces inconsistencies. In France, for example, you can verify from Free Mobile, SFR, Orange, and Bouygues; in the US from AT&T, T-Mobile, and Verizon. Dedicated plans let you rotate on demand to re-request a placement under fresh carrier IPs.
Yes. Proxy4G is no-KYC: no government ID, name, address, phone, or card. Your account is auto-created on first order and paid in cryptocurrency (BTC, ETH, SOL, USDT). We do not log destination traffic, so your competitive and compliance checks stay private from the providers you are verifying.
Shared rotating proxies start at $10.80/month and dedicated proxies start at $27/month, billed in 1, 3, 6, or 12-month terms (longer terms lower the effective rate). Rates vary by country and configuration — see the pricing page for exact per-country figures, then build your order in the configurator.
