Whitelist domains for G Suite
As a G Suite administrator, you might have users who want to work together in certain Google products with users outside your business or school. You can allow file sharing in Google Drive for organizations that you trust by whitelisting their domain. After you whitelist a domain, you then grant Drive access so that users in your organization can share files and folders with users in the trusted domain.
Users can view, comment on, and edit any shared files. A warning message is turned on by default that asks users to confirm before they share files with a trusted domain. By granting access, you also allow users outside of your organization to share files and folders with users in your domain.
In G Suite for Education, whitelisting domains for Classroom lets you allow users in trusted domains to join classes in your domain. It also allows your users to join classes in the domains that you trust.Whitelist a domain
Sign in to your Google Admin console.
Sign in using your administrator account (does not end in @gmail.com).
- Click Domains > Whitelisted external domains.
Where is it?
- Enter the name of the trusted domain you want to whitelist and click Add.
Note: You can whitelist a maximum of 50 domains. Whitelisted domains must be G Suite domains. If you add non-G Suite domains to the Whitelisted Domains list, they will still not be trusted. Subdomains and domain aliases aren't included when you whitelist a domain, so 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 too.
