You can confirm that the websites and email addresses listed on the profiles of any organization owned by your enterprise account are controlled by your enterprise by verifying the domains. Verified domains for an enterprise account apply to every organization owned by the enterprise account, and organization owners can verify additional domains for their organizations. For more information, see "Verifying your organization's domain."
After you verify ownership of your enterprise account's domains, a "Verified" badge will display on the profile of each organization that has the domain listed on its profile. To display a "Verified" badge, the website and email information shown on an organization's profile must match the verified domain or domains. If the website and email address shown on your organization's profile are hosted on different domains, you must verify both domains. If the website and email address use variants of the same domain, you must verify both variants. For example, if the profile shows the website
www.example.com and the email address
email@example.com, you would need to verify both
Organization owners will be able to verify the identity of organization members by viewing each member's email address within the verified domain.
After you verify domains for your enterprise account, you can restrict email notifications to verified domains for all the organizations owned by your enterprise account. For more information, see "Restricting email notifications for your enterprise account to approved domains."
Even if you don't restrict email notifications for the enterprise account, if an organization owner has restricted email notifications for the organization, organization members will be able to receive notifications from any domains verified for the enterprise account, in addition to any domains verified for the organization. For more information about restricting notifications for an organization, see "Restricting email notifications to an approved domain."
To verify your enterprise account's domain, you must have access to modify domain records with your domain hosting service.
