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

Let your users work in some Google products with users outside your business or school. For example, allow file sharing in Google Drive with an organization you trust by whitelisting their domain. Users in trusted organizations can also share their files with your users.

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.

Requirements

  • The trusted domain must be a domain that uses G Suite
    Confirm with the trusted organization or company that their users have G Suite accounts. G Suite Essentials accounts must be domain-verified, not email-verified.  
  • Currently only Google Drive and Google Classroom support whitelisted domains.
  • For new Google Sites, users in the whitelisted domains can access the site, but can't use in-site search.

How domain whitelisting works 

  • You can turn whitelisting off or on at the organizational unit level but the domain whitelist applies to your whole organization (all organizational units and groups). There aren't separate whitelists for each organizational unit or group.

  • Subdomains and domain aliases aren't included when you whitelist a domain. Add these separately, if needed. For example, if you whitelist the domain, company.com, and they acquire newcompany.com, you need to whitelist newcompany.com to grant access to that organization.
Whitelist a domain
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console Home page, go to Domains.
  3. Click Whitelisted domains > Add new. 
  4. Enter the name of the domain, subdomain, or domain alias and click Add domain to whitelist.
     

    Do not add "google.com" as a whitelisted domain. 

    Adding google.com after August 5, 2020 can block you from sharing with other domains on your whitelist. If you need to share your Drive files or Classroom membership with google.com, learn about your options.
    • Important: When you add a domain name, the whitelist doesn't check whether the domain uses G Suite. To confirm that the domain is a G Suite trusted domain, check the whitelist in the sharing settings for Google Drive and Google Classroom.
    • If you share with users who have an account at subdomain or domain alias, add that domain as well. For example, add sales.solarmora.com to the whitelist. 
Remove a whitelisted domain
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console Home page, go to Domains.
  3. Click Whitelisted domains.
  4. Next to the name of the whitelisted domain, subdomain, or domain alias, click Remove.
    Note: Subdomains and domain aliases aren't automatically included when you remove a domain.
