Activate existing phone numbers in Teams

This guide shows you how to assign phone numbers to your Microsoft Teams users.

1. Sign in to the Teams admin center at admin.teams.microsoft.com.
2. Go to user management: click Users, then Manage users. Search for the user or scroll the list.
3. Select the user: click their name to open their profile.
4. Edit their details: on the profile, click Edit.
5. Assign a phone number: scroll to Assign phone number, enter the number, fill in the required emergency address, then click Apply.
6. Confirm: check the user’s profile shows the new number.

Important: when you activate an existing number, Microsoft briefly disconnects it while it re-syncs with your Microsoft tenant. Expect about 20 minutes of downtime. Once the numbers are back in Teams, you can reassign them to users or resource accounts.
