Your 679 number: how to get one
Two paths take you to a 679 number. A provider hands out a new number with its plan, chosen at sign-up out of the numbers it holds in that code. Sellers post numbers they already own, often with a pattern, at a one-time price. After that, you move the number to a provider.
