Hi there, I’m Shane. I’m a sales engineer, but today I’m blogging about how to add additional domains to Google Apps.

Let’s say you’re running your company Widgets.com on Google Apps. Thanks to unprecedented growth, it’s doing great. So great, in fact, that you’ve decided to launch a new brand, Bobbles.com.

Bobbles.com is going to be huge, and you need to look professional, unifying your new brand with your existing brand. Some existing employees are going to need @Bobbles.com email addresses, and your new Bobbles.com employees will need to be able to easily collaborate with everyone from both brands.

Don’t worry, you won’t need to set up a whole new Google Apps tennant just for these users. You can easily add Bobbles.com to the existing Widgets.com Google Apps tennant.

By adding an additional domain under your Widgets.com Google Apps tennant, you can assign Bobbles.com aliases to your existing Widgets.com users. Then your users can have just one mailbox for both brands, and you only need to use one additional license. In the future, users can be added as @Bobbles.com users from the start. All in all, every user is now part of the same Google Apps tennant, and has the same global address list and collaboration features as the existing users of Widgets.com

How to add additional domains in 5 steps


The first thing you need to do is register your new domain. Providers like enom.com, 1and1.com, and networksolutions.com can all help you with finding an available domain, and registering it for a small fee annually.


Open your Google Apps Admin panel, admin.google.com. In the admin panel, click on “Domains”. Then click on “Add a Domain or Domain Alias” at the top left of the page.


There will be a pop-up window prompting you to insert your domain, and whether you’d like to add it as an “alias domain” or an “additional domain”. Changing options down the road isn’t easy, so it’s important to choose the one that applies best.

Alias Domain vs. Additional Domain 

An alias domain is only used for aliases, and upon creation, automatically adds an alias to all users matching their primary email address. If I created Bobbles.com as an alias domain, bob@Widgets.com would automatically get bob@bobbles.com as well. 

If you select an additional domain, it would allow you to add Bob@bobbles.com to bob’s widgets account, but it would have to be done manually. Additionally though, you would be able to make Bob@bobbles.com his primary login, and not just an alias.

When in doubt, we encourage people to choose additional domain, as it offers more options for control that aliasing doesn’t.


Once you’ve added the domain, you’ll automatically be taken to verify the newly added domain. You need to prove to google that you own the domain before you can act on it’s behalf. You’ll see a dropdown menu with a list of domain registrars. Find yours on the list. Select it, and Google will give you a step-by-step on just how to complete this process, or in some cases, even an automated process.

If your registrar isn’t on the list…

Select “Other” towards the bottom. This will provide you with the contents of a TXT record that you’ll need to to your DNS records. If you’re unfamiliar with this process, check the help documentation available from your registrar or DNS provider. You can also call their support line.


Switch back to the google verification panel, and click “verify”. If you were successful, it will tell you, and return you to your admin panel. If it’s unsuccessful, be patient. DNS updates can sometimes take as long as 24 hours to propagate to where google can see them.

Congratulations! After you add additional domains, you’re ready to start creating aliases, users, and groups all using your new domain name. If you have any questions about this process, ask us in the comments below, or contact Google support.
