Manually submit a port order
For most customers, port orders of 999 or fewer phone numbers can be completed in the Microsoft Teams admin center. For instructions on that process, see Transfer phone numbers to Microsoft Teams.
In some situations, you may have to manually submit a service request to get phone numbers, transfer phone numbers, release phone numbers, or change addresses. To see what's required for each country and region or to learn more about number porting, see Manage phone numbers for your organization.
Use the steps in this article to manually submit a port order if you're unable to use the porting wizard in the Teams admin center.
