Change your primary domain

You can change the primary domain for your organization's Google account. Do this if you no longer want to use your current primary domain, or if you want another domain to be your primary domain. Your users will then sign in and receive email using your new domain name.

Before you begin

Changing your primary domain might not be necessary and can have unintended results. Before continuing, see: 

Change your primary domain in the Admin console

This feature is not available for legacy Free edition accounts, Reseller accounts, domains purchased through a Google partner, or accounts with Chrome or Mobile Device Management licenses. 

You change primary domains by adding the new domain to your Admin console. Then swap it with your current primary domain. Here's how we suggest you proceed:   

1. Add a secondary domain and set up MX records

Add the domain you want as your new primary domain to your Admin console. Be sure to add it as a domain, not a domain alias.

  1. Add your domain as described at Add more domains to your G Suite acacount.

    Important: When prompted, choose the Add another domain option (not the domain alias option).

  2. Verify the domain.

    This is required to make it your primary domain.

  3. Direct the domain's mail to Google servers by setting up its MX Records.

    You can do this now or later.

2. Make the domain your new primary domain
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console dashboard, go to Domains.

    To see Domains, you might have to click More controls at the bottom.

  3. Click Add/remove domains.
  4. Next to your new primary domain, click Make Primary.
  5. Click Change Primary Domain.
3. Rename users to the new primary domain
Before renaming the super administrator account you're signed in with, be sure to record the new name somewhere safe. You will automatically be signed out upon renaming and will need the new super administrator name to sign back in.
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console dashboard, go to Users.
  3. Click a user to open their account page.
  4. At the top right, click MoreMore and then Rename.
  5. Under Primary email address, click the Down arrow Down Arrow and select your new primary domain.
  6. Click Rename user.

The user will now sign in with their address at the new primary domain. Their old address will become an email alias. As long as each domain is set up to for mailflow with Google servers, the user will receive mail at both addresses.

4. Rename groups to the new primary domain
  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console dashboard, go to Groups.

    To see Groups, you might have to click More controls at the bottom.

  3. Click a group you want to rename.
  4. On the group's page, click Edit.
  5. Click the Down arrow Down Arrow, and select your new primary domain.
  6. Click Save group info.
5. Remove the original primary domain (optional)

If you no longer want to use the original primary domain with your Google account, you can remove the domain.

Before removing your original primary domain, make sure there are no existing users or groups using the domain. After you remove the domain, users won't receive emails sent to that domain.

  1. Sign in to your Google Admin console.

    Sign in using your administrator account (does not end in @gmail.com).

  2. From the Admin console dashboard, go to Domains.

    To see Domains, you might have to click More controls at the bottom.

  3. Click Add/remove domains.
  4. At the right of the [original_primary_domain].test-google-a.com domain, click Deactivate. Then confirm you want to remove that domain.
  5. Next to the original primary domain you want to remove, click Remove.
