Getting the right info to port a Skype number

Question

I need all port-out details required for my new carrier (Mint Mobile) to transfer my Skype number, including the Account Number and a PIN or port-out code.

Answer 1

Dear @David Bartels,

I understand you need the exact account number and PIN to transfer your Skype number over to Mint Mobile.

To port your number out, you do not need to request a specific port-out code from Skype. Instead, the process is initiated entirely through your new carrier (Mint Mobile) using standard default credentials that Skype shares with the telecommunications industry.

When Mint Mobile asks for your port-out details, please provide the following information:

• Account Number: Your full 10-digit Skype Number (without spaces, dashes, or the country code +1). For example: 5551234567. Note: If Mint Mobile's system rejects this, try using your full number with the country code, such as 15551234567.
• PIN: 0000 (four zeros). This is the universal default PIN used by Skype for all automated port-out requests. Please refer to similar topics on the forum: skype phone number - Microsoft Q&A
• Service Address: Use the physical billing address currently on file in your Skype account. You can verify or update this by logging into your account on the Skype website and checking your billing profile.

Crucial steps for a smooth transfer

• Keep the Account Active: Do not cancel your Skype number subscription until you have confirmed that the number has successfully activated on Mint Mobile. If you cancel it beforehand, the porting process will fail.
• Proof of Ownership: If Mint Mobile asks for a Customer Service Record (CSR) or a copy of a bill to prove you own the line, you can take a screenshot of your Skype account portal showing your name alongside the Skype Number and use that as verification.

You can find the formal instruction to initiate this transfer directly with your new carrier on the official Microsoft Support page: How do I port my Skype Number to another company? - Microsoft Support 

I hope this information helps you complete your transfer to Mint Mobile smoothly. Please let me know if Mint Mobile requests any further specific documentation from Microsoft.

Answer 2

Skype does not provide a traditional “account number + PIN” for porting like a mobile carrier. For Skype Numbers, the required port-out information is obtained and handled differently depending on the country.

General rule for porting a Skype Number:

1. The new provider (Mint Mobile) must initiate the port request.
2. Provide Mint Mobile with your Skype Number and your personal/account details exactly as they appear on your Skype account.
3. If the number is in a country that uses a specific port-out code (for example, France), you must obtain that code and give it to the new provider.

Country-specific details from the context:

1. France Skype Numbers (Voxbone/Bandwidth)
   • Required port-out code: RIO (Relevé d'identité opérateur).
   • How to get it:
     • Call the Voxbone/Bandwidth toll-free number: +33805080975.
     • Request the RIO for your Skype Number.
     • You will receive the RIO via SMS.
     • If the RIO is not received within 2 days, use the “request RIO via email” option.
     • After requesting by email, you can open a case with Skype customer support stating: “Email RIO for Number XXXX” so they can provide the RIO.
   • Regulatory note: Portability is free of charge and must be requested through the new operator; no refund of previously paid Skype service fees is provided.
   • For Mint Mobile: provide the RIO code as the port-out credential (this serves the role of a port-out code/PIN).
2. Sweden Skype Numbers
   • Swedish Skype Numbers are being discontinued as of December 31, 2025 due to regulatory changes.
   • Porting is allowed: you can port your Swedish number to another provider by contacting the new provider as soon as possible.
   • The instructions for porting out are the same general Skype porting guidance: the new provider initiates the port, and you supply any information they request based on that guidance.
   • If the number is not ported before the termination date, it will be deactivated and cannot be recovered.
3. Other countries
   • The context does not define a specific “account number + PIN” format for Skype Numbers outside the France RIO process.
   • The documented requirement is: contact the new provider directly to initiate porting and provide whatever information they request (typically the Skype Number and subscriber details). If the number is in France, the RIO is explicitly required.

Important clarifications for Microsoft Teams/Mint Mobile

• Skype Numbers cannot be transferred to Microsoft Teams Free personal accounts, and Teams Free does not support PSTN phone calling.
• Phone calling options (and number porting into Microsoft) are only available in Microsoft Teams for business with appropriate Teams Phone licensing; this is separate from porting to a mobile carrier like Mint Mobile.
• For porting to Mint Mobile specifically, use the Skype port-out process above and then supply Mint Mobile with:
  • The Skype Number.
  • The RIO code if the number is French.
  • Your subscriber details exactly as on your Skype account.
  • Any additional fields Mint Mobile requires (they may map RIO or similar codes into their “PIN/port code” field).

If the Skype Number is French, the RIO is the key port-out credential Mint Mobile will need. For other countries, the new carrier must rely on the standard Skype port-out process and your subscriber details, as no separate PIN format is documented in the provided context.
