France Porting Process 

  1. Submit your Porting request with all the requirements in place to
  2. Twilio approves the port request. If everything in Step 1 is correct, you can expect Twilio to approve your port request within 24 hours.
  3. Twilio submits number to the Carrier Partner. This can take up to 24 hours. Your request is then submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier and keep your numbers active.
  4. Twilio’s Carrier Partner reaches out to the Losing Carrier. This can take around one week to complete.
  5. Response from the carrier. At this point, your request is either approved or rejected:
    • Approved: If approved, Twilio will notify you about a porting date. 
    • RejectedRejections can occur due to various reasons. For example, invalid RIO Code or invalid/incomplete range of numbers. Read more about common reasons for port request rejections here. Additionally, you will likely need to reach out to your losing carrier to find out what’s needed to move forward. Rejections may add an undetermined amount of time to your porting request.
  6. Twilio reaches out to you with a porting date. Twilio sends you an email with a porting date and time slot if known. Your number is on your Account and can be visible in the Twilio Console.
  7. Configure your number. It is critical to configure your number prior the porting date. This will minimise the service downtime. You can configure the numbers from the Twilio Console.
  8. Your phone number is with Twilio. Once your number(s) is routing to Twilio and everything works as expected, you can remove the number(s) from your former provider.
