# Domain verification

> Prepare domain ownership and identity-routing requirements without assuming a self-service verification workflow.

Domain verification establishes that an organization controls a domain used for an identity configuration. It is separate from verifying one person's email address or inviting that person into a workspace.

<Note>
  Threetone has no released self-service domain-claim, DNS-challenge, or verification-status management workflow. The SSO sign-in entry uses organization-domain lookup, but that lookup is not a domain-verification process or proof of exclusive domain ownership.
</Note>

## Prepare the domain review

You need the workspace owner, the domain's DNS administrator, and the person managing your identity provider.

<Steps>
  <Step title="Inventory the domains" id="domains-inventory">
    Record primary email domains, subdomains, aliases, and any domains shared by separate organizations. Identify who can authorize changes to each one.
  </Step>

  <Step title="Define routing and membership expectations" id="domains-routing">
    Decide which workspace an employee should reach and how external collaborators should sign in. Domain matching must not be assumed to grant membership or resource access.
  </Step>

  <Step title="Obtain supported setup instructions" id="domains-setup">
    Contact the [Help Center](https://help.threetone.in/en) with the workspace and domain requirements. Use only challenge values and DNS records supplied through an approved setup process. No generic TXT value is documented here.
  </Step>
</Steps>

Continue with the [SSO readiness guide](/overview/administration/workspaces/sso) to plan provider configuration, recovery access, and provisioning separately. Do not remove an existing sign-in route until the intended users and administrators can use its replacement.

  <Accordion title="Does verifying my email verify the company domain?" id="domains-faq-email">No. Email verification identifies control of a mailbox; domain administration is a separate responsibility.</Accordion>
  <Accordion title="Does a matching domain automatically add workspace members?" id="domains-faq-membership">No such automatic membership guarantee is established by the SSO domain lookup.</Accordion>
