Change your primary domain from the Admin console

Have you recently re-branded your business name or purchased a new domain name? If so, you can update your G Suite account with your new business name by renaming your primary domain. Your users will then be able to sign in and send or receive email using your new business name. The following procedure lets you change your primary domain by switching it with an existing secondary domain from the Google Admin console.

Tip: Changing your primary domain isn't always necessary and can have unintended consequences. Before changing your primary domain, see Before you change your primary domain and Alternatives to changing your primary domain.

Change your primary domain using the Google Admin console

This feature is not available for Reseller accounts, DNS Domain Names purchased through a Google Partnered Domain Registrar, or accounts with Chrome or Mobile Device Management licenses. You also cannot change Standard edition domains.

Note: If you purchased your G Suite licenses from a Reseller, notify them before making any changes to your domain name.

Note: If you want to make an existing domain alias your new primary domain name, you must first remove the domain alias and then complete the steps below.

The recommended sequence of tasks for changing your primary domain using the Google Admin console is as follows. However, you can create the MX records for your new domain whenever you prefer.

1. Add a secondary domain and create MX records

To begin, you must add a secondary domain. You'll later swap the name you give to the secondary domain with the primary domain. After verifying your ownership of the domain, set up your domain's MX records to direct mail to the servers:

  • To add another domain, go to Add a domain or domain alias. Be sure to choose the Add another domain option and enter the new domain name before continuing.
  • Also be sure to Verify your domain; otherwise you will not be able to make it your primary domain.
  • To create the MX records for the new domain, go to Set up MX Records. If you prefer, you can create the MX records later.
2. Assign the secondary domain as 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 Make Primary to the right of the domain name you want to be your new primary domain.
  4. Click Change Primary Domain.
3. Rename users to the new primary domain

Before renaming the super administrator account you are signed in with, be sure to record the new name somewhere safe. You will automatically be signed out upon renaming and will require the new super administrator name to sign back in.

Tip: If you have more than 50 users, you can instead rename your users all at once with the using the Directory API.

  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 Edit to the right of the user you want to rename to the new primary domain, and enter the new name.
  4. Click the Down arrow Down Arrow, and select your new primary domain.
  5. Click Rename user.

After a user is renamed, the original primary domain is automatically added as a user alias and ensures that the user will continue to receive e-mail sent to the original domain.

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 the group you want to rename.
  4. 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 own your original primary domain, or if you want to remove it from your account, follow these steps.

Before removing your original primary domain, you must ensure that no existing users or groups are currently using the original primary domain before you can remove it. After you remove the original primary domain, your users will be unable to receive emails sent to that domain.

Also, if you delete the old original primary domain from the list of secondary domains any secondary calendars created before the rename will be deleted automatically.

  1. Sign in to your Google Admin console.

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