Local number portability (LNP) has been around since the mid-nineties and is now the mainstay of both wireless and wireline providers. Direct Inward Dialing numbers (DID) are now “owned” by the end user, so to speak. The end user may be an individual with one number or an enterprise customer with hundreds or thousands of numbers necessary for their company telecommunication needs. The end user can keep their number and change providers as much as they wish.
