Local Number Portability

What exactly is Local Number Portability (LNP)?

Quite simply, LNP, or number porting, is a system that enables end users to keep their telephone numbers when switching from one communications service provider to another. When deregulation came to the telephone industry, many new service providers emerged, giving consumers a choice of services and prices. Yet, switching to a new provider meant getting a new telephone number.

Number portability changed that, making it easy for consumers to freely select the communications service provider of their choice and retain the same telephone number. Read more about the history of LNP, why it exists, how it works and how it is managed.
