France porting process

  1. Submit your Porting request with all the requirements in place. Send your request to porting@twilio.com.
  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 our carrier partner. This can take up to 24 hours. Your request will then be submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier - your phone number(s) must be kept active.
  4. Twilio’s new carrier partner reaches out to the existing (losing) carrier. This can take around one week to complete.
  5. Losing carrier responds. At this point, your request is either approved or rejected:
    • Approved: If approved, Twilio will notify you about a porting date.
    • Rejected: Rejections can occur due to various reasons. For example, invalid RIO Code or invalid/incomplete range of numbers. For more common reasons for port request rejections, see Why was my port request rejected. You will also 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 attached to your Account, and can be seen in 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 Twilio Console.
  8. Update Geographic Permissions. To prevent errors with outbound communications, be sure to enable countries you plan on contacting in Voice Geographic Permissions and/or Messaging Geographic Permissions.
  9. Your phone number is now live 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.

Notice: We charge a one-time porting fee for France, for more details please reach out to porting@twilio.com.
