Getting phone numbers for your users

Before you can set up users in your organization to make and receive phone calls, you must get phone numbers for them.

You have two ways of getting numbers for your users:

  • Get new numbers using the Skype for Business admin center.

  • Port or transfer your existing numbers from your current service provider or phone carrier to Office 365.

You must use the Add new user numbers page to see, search, acquire, and reserve those numbers. You can search by Country/Region, State, and City, and then enter the number of phone numbers you will need for your users.

Note

If you need help setting up phone numbers for your organization, you can Contact support for business products - Admin Help.
