Get an 830 number
There are two ways to get an 830 number. A provider gives out a new number along with its plan. That number is picked at sign-up from the numbers the provider holds in the code. Numbers a seller already holds are listed for a one-time price, often carrying a pattern. You then move the number over to a provider.
