If you use Google Voice as a consumer user or as an unmanaged Google Workspace user, that means you agree to the Google Voice Additional Terms of Service.
If you're using a Google Voice for Google Workspace account managed by your work or school, terms may apply based on your organization’s agreement with Google. In addition to the Google Workspace terms, use of Google Voice is subject to the Google Voice Service Specific Terms and the Google Voice Privacy Disclosure.
