Anthropic has tightened access rules to Claude for unsupported regions

The company Anthropic has updated the geographical availability rules for its products. The new policy came into effect on November 12, 2026, and affects the developer's entire line of services.

Restrictions now apply not only to users from unsupported countries but also to any companies registered in such jurisdictions. The rule also affects organizations that are directly or indirectly controlled by residents of excluded regions. The new requirements cover the Claude assistant, the Claude Code tool, Cowork, the API, as well as models available through cloud platforms and official intermediaries.

The new regulation introduces strict personal and corporate filters. An employee from an unsupported country will not be able to use the company's services even if they are physically located in an authorized jurisdiction. The reverse restriction applies to employees of legal companies while traveling to blocked regions.

The changes are forcing international teams to reconsider their legal entity ownership structures and developer hiring locations to maintain access to Anthropic's infrastructure.
