Getting your own 748 number
Two routes take you to a 748 number. With its plan, a provider hands out a new number, chosen when you sign up from the pool it keeps for this code. Numbers a seller already has are listed for sale, often with a pattern, at a one-time price. After that you move the number to a provider.
