    1. Under Country or region, select a country or region.

    The number of phone numbers for users (subscribers) is equal to the total number of Domestic Calling Plan and International Calling Plan licenses you have assigned multiplied by 1.1, plus 10 additional phone numbers. For example, if you have 50 users in total with a Domestic Calling Plan and/or International Calling Plan, you can acquire 65 phone numbers (50 x 1.1 + 10). Note that if you have a Pay-As-You-Go Calling Plan, you can only acquire 1 phone number per license assigned.

    For details, see How many phone numbers can you get?. If you need to get more phone numbers than this, contact Support Contact for Business Products - Admin Help.

To port/transfer 999 or fewer phone numbers for your users, upload the completed and signed LOAs in the Microsoft Teams admin center for further processing.

To port/transfer more than 999 phone numbers or if you experience issues with the porting process in the Microsoft Teams admin center, you can manually submit a port order to the TNS Service Desk for your region.
