According to CoinMeta, the new version of the "Supported Regions Policy" Claude officially took effect on November 12th. Existing users were suddenly prompted to undergo KYC identity verification, and some users had their accounts suspended after submitting their Chinese passports. There are discussions in the community about whether there are different risk control standards for accounts from different regions. Anthropic clearly stated in its September security report that accounts from regions that are not supported, such as China, would trigger identity verification, and failure to pass the verification would result in account suspension. The new policy further clarifies the scope of restrictions; users who work for companies located in unsupported regions or who are affiliated with overseas companies controlled by individuals or enterprises from these regions do not meet the usage criteria. To this day, Anthropic has not yet announced the number of accounts affected by this identity verification or the number of accounts that have been suspended.
