Add a user alias domain or secondary domain

For your Google Workspace or Cloud Identity account

If you own another domain, you can add it to your Google Workspace or Cloud Identity account. For example, you might manage multiple businesses or brands, each with their own domain. Depending on your needs, you add a domain as a user alias domain or a secondary domain.

If you try to add a domain that includes "gmail" in its name,  it won’t be accepted. For example, if you try to add a domain such as xxgmailxx.com, you’ll get an error.


Give users an email address at another domain
OR      
Manage separate teams of users or businesses at different domains
 

   

  • Users get email addresses at both domains.
 
  • You have different users for each domain.
  • Users can send and receive email from either address
 
  • A user gets a Google Workspace account, email address, and mailbox for their domain
  • No extra cost per user 
 
  • Pay for each user account that you add to your secondary domain*

Add a domain to your account

  1. Sign in with an administrator account to the Google Admin console.

    If you aren’t using an administrator account, you can’t access the Admin console.

  2. Go to Menu and then Account > Domains > Manage domains.

    Requires having the Domain settings administrator privilege.

  3. In Manage domains, click Add a domain.

    Note: If you have the legacy free edition of G Suite, the "Add a domain" option isn't available.

  4. Enter the name of the domain you're adding.

    If you recently removed this domain from your Google Workspace account, you need to wait up to 24 hours before adding the domain. Check troubleshooting tips.

  5. Select a domain type:
    • Secondary domain
      • if you plan to replace your primary domain with this new domain. 
      • if you want to add a new domain for a separate team or business unit.
    • User alias domain:
      • if you want to add email aliases (alternate email addresses) for your existing users. Google Workspace will automatically create aliases after you've added the domain.
  6. Click Add and start verification.

    Follow the instructions to verify that you own the domain.

  7. If you want to use Gmail with this domain, return to Manage Domains after your domain is verified. Find the new domain and click Activate Gmail.

    Follow the instructions to set up Gmail for your new domain.

Start using your new domain
