Supported phone number types

In France we offer porting for the following number types:

  • Geographic (local) (+331 to +335)
  • Non-Geographic (National) (+339)
Please note that we no longer offer porting for Mobile numbers (+336, +337) due to the local regulatory change.

Notice: Please note that most international phone numbers (non-US based) have VOICE capability only. Outside of the +1 region (US and Canada), only mobile numbers support both VOICE and SMS. Below are instructions for porting French phone numbers into Twilio. You can find porting summary and timelines here.

France porting process

  1. Submit your porting request with all the requirements in place 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 business hours.
  3. Twilio submits the number to the Carrier Partner. This can take up to 24 business 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. 
    • Rejected: Rejections can occur due to various reasons. For example, invalid VAT Number 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 emails you 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 to the porting date. This will minimize 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.

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