Get hold of a 224 number
A 224 number can come through two routes. A new number comes with a provider plan, selected at sign-up from the numbers that provider holds in the code. On a seller's list you will find numbers it already has, frequently with a pattern, sold for a one-time price. You afterwards move the number to a provider.
