Domain claiming lets Enterprise admins discover, claim, and migrate existing personal Claude accounts (Free, Pro, and Max) on a verified company domain into their Enterprise workspace. This gives your organization a clean path to consolidate accounts on day one of an Enterprise deployment, and allows people using Claude on personal accounts to keep their work. Domain claiming is available for Enterprise plans, whether purchased directly through Anthropic or through the AWS Marketplace, and works the same in both cases.
Domain claiming is supported on Claude Enterprise plans only.
Team plans can verify a domain and block new personal accounts from being created, but admins can't claim or migrate existing accounts. People on a Team plan can still migrate their own personal accounts voluntarily—see Move your personal Claude account to a Team or Enterprise organization.
Prerequisites
Before you can enable domain claiming, your organization must have all of the following in place:
Restrict organization creation on your verified domain.
Complete domain verification (DNS).
Enforce SSO (not just configured—SSO must be actively enforced). See Set up single sign-on (SSO).
Enable JIT provisioning or SCIM. See Set up JIT or SCIM provisioning.
These prerequisites exist to prevent people from being locked out of Claude during the migration process. If SSO is enforced and provisioning is active, everyone on your domain will have a path to sign in after their accounts are migrated.
