To port your numbers away from Twilio, you will need to submit a request with the carrier to which you'd like to port your numbers. Most carriers require you to fill out a Letter of Authorization (LOA), on which you'll need to provide the end user's full name, the Account SID, and the service address. Please contact porting@twilio.com to request the service address for your number.
Please note that portability rules vary by country, and not all countries provide for portability.
Once the gaining carrier has gotten in touch with Twilio about your port, you can expect to receive a notification email from us. You will also find your pending port-away numbers listed below.
