Telephone Number Services (TNS) - Service Desk
As of July 22, 2021, the previous email system to reach out to the TNS service desk has been retired.
There is a new process to interact with the Telephone Number Services (TNS) service desk from our new Phone Number Service Center. You can now open tickets, view tickets, and track communication in a single place that is integrated with the Teams Admin Center. These tasks are described in more detail in the following sections.
Create a new case – Submit a new request or general enquiry.
View my existing cases – Track and monitor your existing case(s).
View my company cases – Track and monitor your company's existing case(s). If your colleagues from your company have opened any cases, you can look those up in this view.
Give feedback– Share your feedback with us.
Create a new case
Only someone from the same tenant is allowed to create a case. For example, someone from @fabrikam.com can't create a case on behalf of @contoso.com.
To create a new case, follow these steps:
Select Create a new case from one of the following places:
From the Phone Number Service Center home page, at the top of the page or at the bottom tile.
From the View my existing cases page.
From the View my company cases page.
Provide your case details as described in detail in the next section.
After entering all values, select Submit. You'll see a new screen where you can see your case number.
Provide case details
To understand case details, Microsoft needs the following information:
- Case category
- Country or region
- Case type
- Case title
- Additional contacts for notifications
- Additional supporting documents
A case can have one of two categories:
Submit a new request- Choose this option if you want to submit a new request. For example, you want to submit a port request or you want to purchase phone numbers from Microsoft.
General enquiry - Choose this option if you have questions that will help you determine your request. For example, you need to know if you can port your wireless numbers to Microsoft, or you need to know if Microsoft supports vanity toll-free numbers.
Country or region
Select the country/region for which you are submitting this case. If you have requests for multiple countries, you must open one case per country/region.
Case type can be one of the following:
Custom Calling Name (US Only) - Set a custom calling name on your Microsoft phone numbers. This is applicable to United States phone numbers only.
Custom calling name to set (15 chars only) - The custom calling name that you want to set. Name has a maximum limit of 15 characters.
List of phone numbers - The list of phone numbers for which you want to set a custom calling name value. Upload a csv file with the list of phone numbers.
