To port your toll-free number, you must authorize your new carrier to work with your current carrier to release ownership of your number via a Letter of Authorization (LOA). The simplest way to help your port go off without a hitch is to verify that the information in the LOA you send to your new carrier exactly matches the information held by your current carrier, and that it is properly authorized.
When you begin the porting process, consider requesting a copy of your CSR (customer service record) from your provider so you can verify the information in your authorized port-out request. This document contains relevant information connected to your toll-free number. Submitting your CSR alongside your port request can resolve any confusion before it starts. Once your port is underway, we also recommend setting up messaging URLs prior to your port date to help safeguard against disruptions.
