Add more domains to your G Suite or Cloud Identity account
If you own other domains, you can add them to your G Suite or Cloud Identity account. You can also add a subdomain, for example, partners.your-company.net.
|
your-company.net |
+ |
other-company.com |
When you add another domain, you can give existing users email addresses at the domain or create new users at the domain.
If you want to switch your primary domain to another domain, see these steps.
STEP 1. Choose how to use your domain with G Suite or Cloud Identity
Decide whether to add your domain as a domain alias or as an additional domain.
Option 1: Give existing users an email address at the domain
Add the domain as a domain alias.
| ✓ | Each user gets an email address at both your primary domain and domain alias |
| ✓ | Each group (such as @info or @support) also gets an email address at the domain alias |
| ✓ | Everyone can send and receive email from either address |
| ✓ | All messages arrive in the user’s current inbox |
| ✓ | No additional cost per user or group. Add up to 20 domain aliases. |
Example: Ann signed up for G Suite or Cloud Identity with your-company.net. She also owns other-company.com and adds it as a domain alias. She and all her team automatically get email addresses at both domains. They manage all messages from their inbox at your-company.net.
 |
ann@your-company.net |
 |
matteo@your-company.net matteo@other-company.com |
Option 2: Create new users at the domain
If you have the legacy free edition of G Suite, upgrade to G Suite Basic to get this feature.Add the domain as an additional domain.
| ✓ | Good for managing separate teams of users or businesses at different domains |
| ✓ | Create user accounts for the additional domain |
| ✓ | Each domain has a different set of users |
| ✓ | Users have their own G Suite or Cloud Identity account, email address, and mailbox for their domain |
| ✓ | Pay for each user account in the additional domain |
Example: Ann manages two separate teams. Each has their own domain. She adds other-company.com as an additional domain in G Suite or Cloud Identity.
Each team member has their own email address, mailbox, and user account for their domain. She manages all domains and users in her Admin console at your-company.net (her primary domain).
| your-company.net Team | other-company.com Team | ||
| ann@your-company.net nguyen@your-company.net lyle@your-company.net |
aditya@other-company.com coraline@other-company.com vincent@other-company.com |

STEP 2. Add the domain alias or additional domain
-
Sign in to your Google Admin console.
Sign in using your administrator account (does not end in @gmail.com).
-
From the Admin console Home page, go to Domains.
To see Domains, you might have to click More controls at the bottom.
- Click Add/remove domains
Add a domain or a domain alias.
- Choose how to add the domain:
- Add a domain alias of primary-domain-name: This gives everyone in your primary domain an email address at the alias domain. (Note: To add a domain alias to secondary domain, you must use the Domains Aliases API.)
- Add another domain: Adds a separate, additional domain with its own users.
If you have the legacy free edition of G Suite, upgrade to G Suite Basic to get this feature.
- Enter the name of the domain or subdomain to add. You must own the domain name, and it can't be used with any other Google Account. If the domain is already in use, you’ll get an error message. See troubleshooting tips.
- Click Continue and verify domain ownership
Follow the instructions to verify that you own the domain. If you need assistance, contact your domain host (typically where you purchased your domain) or G Suite Support. - Click Verify and continue to setup email delivery.
- Update the domain's MX records to set up Gmail (G Suite only) for your added domain.
- Click I have completed these steps.
Add a domain or a domain alias.For large organizations: It can take more than 24 hours after verification for all users and groups to receive their alias email addresses.
Once your domain is active, see the Step 3 below to set up your users with their new email address or account.
STEP 3. Set up your users with the new domain
For a domain alias
Once your domain alias is active, messages sent to addresses at your domain alias automatically arrive in users' inboxes. To test, send a message from another account (not your G Suite account) to your new address.
To send messages from their new address, users must add the address to their Gmail account. Share the sample message and instructions with your G Suite users.
For an additional domain
Once your additional domain is active:
- Add each user to the domain in the Admin console.
- At the right of the @ sign, choose the user's domain from the dropdown list.
We recommend reviewing Limitations with multiple domains for help with managing users accounts.
