After assigning licenses to users for Teams Phone, you’ll then need to assign phone numbers and emergency locations.

In European countries/regions, the emergency location is associated with the phone number when you get it from Microsoft 365 or Office 365 or when you transfer a phone number over to Microsoft 365 or Office 365. In the United States, the emergency location is associated with the phone number when it’s assigned to the user. The emergency address can be changed if the user that it’s assigned to moves to a new location.


Complete the following steps to assign phone numbers to users:

  • To assign a phone number in the Teams Admin Center, perform the following steps in written order:
  • Navigate to the Teams admin center at
  • Sign into the Teams admin center with an account that has the Teams Administrator role.
  • In the left navigation, select Voice > Phone numbers.
  • On the Phone numbers page, select an unassigned number in the list, and then select Edit.
  • In the Edit pane, under Assigned to, search for the user by display name or username, and then select Assign.
  • To assign or change the associated emergency location, under Emergency location, search for and then select the location.
  • Depending on whether you want to send an email to the user with their phone number information, turn off or turn on Email user with telephone number information. By default, this option is turned on.
  • Select Save

Get-CsOnlineTelephoneNumber | ft Id,ActivationState

To retrieve a list of emergency locations that are validated, use the following cmdlet:

Set-CsPhoneNumberAssignment -Identity "<User name>" -PhoneNumber +15555037311 -LocationID $locID.LocationID
