How do I submit a port request to Twilio?
To begin the porting process, please log into your account and go to the porting page. You will need to provide us with your billing address and contact information. We will also require that you fill out a Letter of Authorization and provide a scanned (or electronic) copy of your most recent phone bill (Within the last 30 days) that includes your account and address information for all the numbers you’d like to port.
Make sure all the information provided matches the service information on file with your current carrier. You can call them prior to submitting your request to ensure the information matches.
