Adding a domain to Workspace
How to add a second or alias domain to your Google Workspace account — so you can create email addresses at multiple domain names.
You might need more than one domain on your Google Workspace account — for example, if you have a secondary business domain, a rebranded domain name, or a country-specific version of your domain.
Quick summary
In the Admin console, go to Account → Domains → Add a domain. You can add a primary domain, a secondary domain (separate users and email), or an alias domain (same users, different email addresses). You'll need to verify ownership by adding a DNS record, which usually takes a few minutes.
Types of additional domains
| Type | What it does |
|---|---|
| Secondary domain | A separate domain with its own users and email addresses |
| Alias domain | All users get an additional email address at the new domain (e.g. everyone at company.com also gets company.co.uk) |
Most small businesses use alias domains when they add a second domain.
What you'll need
Admin access required 15–30 minutes- Admin access to the Admin console
- Ownership of the domain you're adding
- Access to the DNS settings for that domain (often through your domain registrar or Cloudflare)

Adding a domain
Go to admin.google.com and sign in.
Click Account in the left sidebar, then Domains, then Manage domains.
Click Add a domain.
Choose the domain type — secondary domain or alias domain.
Enter the domain name you're adding (e.g., yourcompany.co.uk) and click Continue and verify domain ownership.
Verify ownership. Google will show you a TXT record to add to your domain's DNS settings. Copy this record.
Add the TXT record to your DNS. Log in to your domain registrar (or Cloudflare, if you use it) and add the TXT record exactly as Google specifies. See How to give us access to your DNS if you need help.
Return to the Admin console and click Verify. DNS can take a few minutes to propagate — if it doesn't verify immediately, wait 5–10 minutes and try again.
Set up email delivery for the new domain. After verification, Google will walk you through adding MX records for the new domain so email can be delivered.
DNS propagation takes time
After you add DNS records, changes can take anywhere from a few minutes to 48 hours to fully propagate. In practice, most records take 5–30 minutes. If verification fails, wait and try again.
After adding the domain
For an alias domain
All users automatically get an email address at the new domain. For example, if you add company.co.uk as an alias of company.com, sarah@company.com also receives email sent to sarah@company.co.uk.
For a secondary domain
You can now create users with email addresses at the new domain. In the Admin console → Users, add a new user and choose the new domain from the dropdown when entering their email address.
Removing a domain
If you need to remove a domain from your Workspace account:
Go to Admin console → Account → Domains → Manage domains. Click the domain, then look for a Remove option. You can only remove a domain if no users have email addresses at that domain.
