Is Claude blocked
in China?
The source result for claude.ai. Network evidence and provider restrictions stay separate.

Raw reachability score
A responding domain or CDN edge does not prove signup, API access, model inference or availability for every user.
- Source evidence count
- 205
- Reported method(s)
- tcp-reset
- Provider restriction flag
- true
Vendor geo-restriction: the provider does not serve this country, so the service is unavailable. A CDN edge may still be network-reachable (see network_reachability_score) — that is not the same as the service working.

Confidence, original provider reference and raw fields
Source confidence: 1. The implementation derives this heuristic from record count and stored evidence confidence. It is not a calibrated probability of censorship, and it is never calculated as 1 minus reachability here.
The original site's undated provider list flags Anthropic in China. That list has no per-entry date or policy citation. It does not override this source read or establish current account eligibility. Check the provider’s current product information ↗

}Read this result carefully.
A classified network signal describes the retrieved source sample. It is not a guarantee for every ISP, account or app feature. A provider restriction can coexist with a responding domain; a source policy flag does not prove government blocking.
The source combines retained evidence with seven-day probe records. Its response time is not the latest observation date. Unknown, unavailable, zero and partial results remain distinct. Source confidence is a heuristic, not a calibrated probability.
The original context.
The complete, distinct editorial text from this guide is preserved below. It is undated source commentary, not a fresh verification of provider policy, cause, reliability or account eligibility.
The situation
Two things make Claude unavailable in mainland China: the Great Firewall filters foreign services, AND Anthropic does not offer Claude in China (vendor geo-restriction). Both point the same way — unavailable.
How the original guide reads a verdict
claude.ai sits behind a CDN whose edge can still answer from inside China, so raw network-reachability can look high — but that is the edge responding, not Claude working. With Anthropic geo-restricting China, the honest verdict is unavailable; we show the raw reachability number only for transparency.
The source may overlay a vendor policy onto its status. A low domain score or a method label alone does not prove the cause claimed in historical commentary. Use the explicit source fields above.
Alternatives described in the original guide
- A VPN to a supported region remains the reliable path.
- Provider terms still apply even where the network is reachable.
These are preserved descriptions, not new guarantees of reliable access. Network reachability does not remove provider eligibility or account restrictions.
