Get access or request to your company’s D-U-N-S number
If you want to associate your mobile app with your business (strongly recommended), you will need to register for or have access to your DUNS number. If you are an Australian business, you can access or request yours here. DUNS number is a unique 9-digit number that is used to identify a business based upon its location. This number will be required to complete the registration of your Apple developer account and Google Play as well. These accounts will be required and consequently your DUNS number is required for you to be able to host your app in both App Store and Google Play.
Here you can find all the details that Google Play will require you to have handy.
You may already have your DUNS number assigned to you which you can look it up and find it here. If you have not signed up to receive your DUNS number, please do so here. Please be mindful that this may take up to 7 business days to complete.
