Number Migration - Not Portable numbers and Substitution Options

Not Portable numbers

Why is my number not portable?

There are many reasons why a number might not be portable.  Some common reasons why a number is not portable include:

  1. Porting is not allowed in the number’s region or jurisdiction
  2. An alternative provider isn’t currently available in the number’s region
  3. A specific number’s configuration includes a non-portable attribute for legal or regulatory reasons (e.g. an individual number assigned to a larger number block that can’t be separated), which prevents us from moving it to another provider

If you have any nonportable numbers on your migration list, you may release them and purchase the substitute numbers immediately (see Nonportable Number Substitution Options below). Alternatively, you may continue using the nonportable number(s) until your provided disconnection date.  If you don’t release the nonportable number(s) prior to the disconnection date, they will be removed on the date provided in your email notification.
