Anthropic closes Claude to employees of Belarusian companies from 12 November

From 12 November, Anthropic is clarifying its restrictions for organisations from unsupported regions, Belarus among them. Employees of companies registered in such countries or headquartered there will not be able to use Claude and other Anthropic services, even if they are themselves located abroad.

Anthropic has updated its supported regions policy. According to it, the employee's location does not matter. If a developer working from Poland or Kazakhstan works for a company registered in Belarus, using Claude as part of that company's activities will violate Anthropic's rules.

The rules apply to all of Anthropic's main products: Claude.ai, Claude Code, Cowork and the API. They also cover Claude models available through cloud platforms and authorised intermediaries.

The restrictions apply to organisations registered in unsupported countries or headquartered there. The ban also applies to companies that are directly or indirectly majority-owned or controlled by individuals or legal entities from such regions, including foreign firms.

Since September 2025, Anthropic has already barred access for companies that are more than half owned by organisations from unsupported regions. In recent months the company has stepped up enforcement of its geographic restrictions.

Users from Russia and China, which are also not on the list of supported regions, have reported account blocks, including when using a VPN.
