Need Customer Service Record or Letter of Authorization

For a Skype Number, the Customer Service Record (CSR) or Letter of Authorization (LOA) is not provided directly to the end user by Microsoft.

To port a Skype Number to another provider (such as Telnyx), the process is initiated and driven by the new provider:

1. Contact Telnyx support and tell them you want to port an existing Skype Number.
2. Telnyx, as the gaining carrier, will submit the port request to Microsoft’s underlying carrier using their own LOA/CSR requirements.
3. If the number is a French Skype Number, first obtain the RIO code:
   • Call the Voxbone/Bandwidth toll-free number: +33805080975 to get the RIO (Relevé d'identité opérateur).
   • If the RIO is not received by SMS within 2 days, use the request RIO via email option.
   • After requesting the email RIO, open a case with Skype customer support stating that an Email RIO for Number XXXX has been requested; Skype support will provide the RIO once they receive it.
4. Provide the RIO (for French numbers) or any other information Telnyx requests so they can complete the port.

There is no separate Microsoft contact to request a CSR/LOA for a Skype Number; the new provider must handle the porting process.
