AI Service IP Check

A common assumption is "if this IP opens ChatGPT, it must open Claude and Gemini too." It doesn't work that way. ChatGPT (OpenAI), Claude (Anthropic) and Gemini (Google) each maintain a separate list of supported countries/regions. The lists don't overlap fully and each provider updates on its own schedule. So the same exit IP routinely yields "ChatGPT works, Claude doesn't" — or the reverse. That's not a bug, it's the list difference.

Roughly, coverage runs widest-to-narrowest as: Gemini (Google states 230+ countries/regions, and began rolling out to Hong Kong in March 2026), then Claude (around 95+ countries/regions after its 2025 expansion, including major EU markets), then ChatGPT (broad, but with several explicit exclusions). All three list mainland China, Russia and Iran as unsupported; grey-zone regions like Hong Kong differ by provider — as of writing, ChatGPT still doesn't serve +852 numbers or Hong Kong IPs, while Gemini has started opening up. The exact lists change anytime, so this page compares your live IP against each provider rather than relying on a memorized list.

That's why this page shows all three verdicts in one view: instead of hitting "your country isn't supported" on each provider's site one by one, you align all three region checks at once — which works, which doesn't, and exactly where you're stuck.

The region gate does one thing: it maps your exit IP's country and compares it against the provider's supported list. Your country is determined first by an IP geolocation database (mapping IP ranges to countries) — which is why a US node showing a US IP usually clears the region gate. But "the IP database says US" is not the same as "the platform treats you as US." Several other signals are easy to overlook.

The second signal is account/region settings. Google's stack (Gemini) leans heavily on your Google account's country/region and history — change the IP without changing the account region and you may still be judged by the account. The third is phone number and billing country. OpenAI requires phone verification and runs VoIP detection — VoIP/virtual numbers are often rejected, while a real carrier SIM passes; your billing country at payment time also factors in. The practical rule: IP, account region, phone number and billing country should all point to the same country. Self-contradiction (US IP, +852 number, Hong Kong billing) is what gets you stopped.

This page's detector nails down the most fundamental of these — your IP's country of origin: it shows which country your current exit IP resolves to and whether that falls inside each provider's supported list. If the region gate fails, phone and billing won't save you; if region passes and it still fails, the cause is in the next section.

This is the confusing case: the IP database places you in a supported country, yet the AI still won't log in, your new account gets flagged within minutes, or you're stuck in a "Verify you are human" loop. Stop blaming the region and split the problem into two buckets.

Bucket 1 — signals don't align (still a region-layer issue). Common with Gemini (IP changed but Google account region didn't) or ChatGPT (US IP but a virtual phone number / mismatched billing country). The fix is to make IP, account region, phone and billing consistent — not just swap the IP. Bucket 2 — region actually passed; you're caught by IP reputation / risk control. Even in a fully supported country, if your IP is datacenter (IDC), a shared public-VPN egress, a heavily-recycled proxy, or blacklisted, the platform (and the Cloudflare edge in front of it) blocks you after the region check — which is why a cheap VPN showing a US IP still can't open ChatGPT.

To tell which bucket you're in, read the IP type (datacenter/residential), nativeness and purity/risk score this page returns: region passed plus a datacenter or high-risk verdict almost always means Bucket 2. The full three-layer mechanism (region → Cloudflare edge → account-level reputation) is covered on our "Why your IP can't open ChatGPT" page; this page focuses on the region overview and first-pass diagnosis.

If your goal is "ChatGPT, Claude and Gemini all working reliably," don't pick an IP by country alone. Check it against these, alongside this page's results: (1) the country falls in all three providers' common supported zone (a real US residential ISP is a common safe choice); (2) type is residential, not datacenter — datacenter ranges are publicly known as non-residential and are the easiest to flag after the region gate; (3) native, not broadcast — registration country matches geolocation, so geo doesn't contradict itself; (4) low purity/risk score with no blacklist hits — multiple sources (AbuseIPDB, Scamalytics, proxycheck, etc.) all see it clean; (5) the /24 neighbor (C-block) profile isn't too dirty and the sharing density isn't too heavy — heavier sharing means inheriting someone else's burned reputation.

Two myths keep biting people: "a paid VPN must be clean" and "more servers / switching often is safer." Both are wrong. Price has nothing to do with IP reputation — most paid VPNs are still datacenter and heavily shared; and one account hopping across countries in a short window is the textbook signal for account sharing / automation. The stable approach: pick one residential, native, clean exit and keep using it, rather than switching constantly.

This page's detector lays out all of the above at once and gives an "AI apps" use-case rating — run your candidate nodes through it and settle on the one that clears all three providers with a clean, native IP. Note that IP reputation is dynamic: "worked yesterday, blocked today" is the signature of a shared egress, so re-testing critical nodes periodically keeps you stable.
