Whitelist trusted G Suite domains

This feature is available with G Suite Enterprise, Enterprise for Education, Drive Enterprise, Business, Education, and Nonprofits edition. Compare editions

As a G Suite administrator, you can let users work in certain Google products with users outside your business or school. For example, you can allow file sharing in Google Drive with organizations that you trust by first whitelisting their domain, then granting them sharing access. Users in trusted organizations can also share their files with users in your domain.

You can also whitelist domains for Classroom to let users in trusted domains join classes in your domain. You can also let your users join classes in the domains that you trust.

Note: Currently only Drive and Classroom support whitelisted domains.

Before you begin

  • Whitelisted domains must be domains that use G Suite. If you add non-G Suite domains to the Whitelisted Domains list, they're still not trusted. 
  • You can turn whitelisting off or on at the organizational unit level but the domain whitelist applies to the whole organization (all OUs and groups). There aren't separate whitelists for each OU or group.
  • Subdomains and domain aliases aren't included when you whitelist a domain. Add these separately, if needed. For example, if you whitelist a domain company.com, and they acquire newcompany.com, you also need to whitelist newcompany.com as a trusted domain to grant access to that organization.
