[Anthropic's New Whitelist Takes Effect November 12; Claude Banned for Companies Holding Companies in Unsupported Regions] Anthropic's newly released Supported Regions Policy will take effect on November 12. The policy changes the availability of products to a whitelist system: Claude.ai, Claude Code, Cowork, API, and Claude models provided through the cloud platform and authorized resellers will only be available in the 185 countries and regions listed. Those not listed will not be supported. The policy's three prohibitions are stricter than the list itself: Use by an individual residing in an unsupported region is a violation, including employees of supported region companies traveling for work; use by entities registered or headquartered in unsupported regions and their personnel is a violation, regardless of whether the individual is actually in a supported region; and personnel of companies directly or indirectly majority-owned or controlled by entities in unsupported regions are also in violation.
