11. Can I manage multiple domains with Google Workspace?

If your organization acquires a new domain name or does business at more than one domain, you can add all your domains to your account at no extra cost.

Users can then have identities at one or more of your domains while sharing services as part of a single organization. And you can manage your domains from the same Admin console. Add a domain as either a separate domain or domain alias, depending on how you plan to use it.
