ChatGPT IP Check

OpenAI gates ChatGPT by region using a blocklist, not an allowlist. In plain terms: the vast majority of countries are supported by default, and only a small set of regions are explicitly excluded. The ones currently outside the supported set include mainland China, Hong Kong, Russia, North Korea, Iran, Cuba and Syria. If your IP's home country isn't on that exclusion list, you've effectively cleared the region gate.

Many people get this backwards. It isn't "only the US works" — it's "only a few places don't work." IPs in the US, Canada, the UK, the entire EU, Japan, South Korea, Singapore, Taiwan, Australia, India and most other countries all resolve to a "supported" verdict on the region dimension. So you don't necessarily need a US IP: a clean Japanese, Singaporean or Taiwanese residential IP clears the region gate just as well, and those exits are often less crowded — and therefore less risk-flagged — than the heavily recycled US ones.

A few edge cases are worth calling out. Hong Kong is geographically part of China but OpenAI lists it separately as unsupported, so a Hong Kong IP also reads as "No." Macau and Taiwan are handled differently from Hong Kong and should be judged against the live verdict rather than assumed. Region policy shifts as OpenAI updates it, so the detector embedded on this page reads your IP's home country in real time and returns the current Yes/No, instead of asking you to memorize a list that may already be stale.

"My IP shows as United States, so why does it still say unsupported?" Usually because a region verdict depends on more than a single geo lookup. Every IP carries two country signals: the geo-located country (where the IP is mapped to) and the registered/home country (where the prefix is registered at its RIR, and which ASN owns it). When the two disagree, you get a so-called broadcast / non-native IP — located in country A but actually registered in country B, common with anycast, relays and re-advertised proxy blocks.

For region availability, the reliable case is a native IP: geo country and registration country match, and it belongs to a real consumer ISP in that country. If your "US node" is really geo-located in the US but registered elsewhere, different services may read different countries for it — you think you cleared the region gate, but some layer still treats you as non-US. Beyond OpenAI, Cloudflare's edge, the app stores and payment processors each run their own geo database, and the verdicts aren't always consistent.

On this page IPOK lays both signals out for you: the detector shows the IP's home country, its ASN, and a native-vs-broadcast verdict. If it flags geo country ≠ registration country, you'll understand why the same "US IP" behaves differently across sites — the issue isn't region policy, it's that the IP's own attribution is ambiguous. Switch to a native IP and the region reading becomes clean and consistent.

Region availability is a "can you get in the door" verdict. Once inside, individual features roll out to different regions at different speeds. Voice mode, Sora video, certain advanced models, memory, and newly launched capabilities typically go live first in the US and a handful of regions, then expand to the EU, Asia-Pacific and beyond. So your IP can read "supported," you can chat normally, yet not see a freshly shipped feature — that's a regional rollout cadence issue, not a sign your IP is dirty.

Another common mismatch is "IP region" versus "account / app-store region." The features and payment options available in the mobile app are driven largely by the store region of your Apple ID or Google account, not only by your current exit IP. An account created on the US App Store but logged in from a Japanese IP can show mismatched or even conflicting features and subscription options. Likewise, once a ChatGPT Plus subscription is bound to a payment country, frequently hopping exit countries afterward tends to draw risk-control attention.

So judging "can I use ChatGPT" is really two steps. First, use the detector on this page to confirm your IP's home country is within the supported set — that's the hard gate. Second, check whether the specific feature you want has rolled out in that region, and whether your account / store / payment country is consistent with your IP region. Separate the two layers and you'll stop misreading "feature not yet available" as "my IP is blocked."

Usage is simple: open the detector on this page and it reads your current exit IP's home country, compares it against OpenAI's supported regions, and returns one of three states — supported / unsupported / unknown. The whole verdict is based on your IP's home country and sends no request to OpenAI, so a single check never touches your account. The same panel also shows IP purity, a datacenter-vs-residential verdict and the native-vs-broadcast comparison, so you see at a glance whether region, cleanliness and attribution all check out.

If the verdict is "unsupported," the problem is region — switch to an IP in a supported region. If it says "supported" but you still can't get in, that's no longer a region issue; it's about IP type, reputation and risk control. We break that part down in a separate page on ChatGPT's three-layer risk-control logic, and don't repeat it here. Read the two together: this page answers "can my region use it," the other answers "region's fine, so why am I still blocked."

On data, to be straight with you: IPOK is maintained by an independent developer — no corporate backing, no paid rankings. The supported-region list changes with OpenAI's official policy, so this page compares against your live home country rather than hard-coding a list that may already be out of date; where a precise figure would help (such as the full current set of supported regions), the live tool fills it in. On privacy we hold a hard line — queries are stateless, the IP you check is never logged, no account, no tracking cookies. We check IPs, not you.
