Get hold of a 707 number
There are two routes to a 707 number. With a provider, a new number comes as part of the plan. It is assigned at sign-up from the pool that provider holds in the code. Sellers post numbers they already hold, often in a pattern, for a one-time price. You then transfer such a number to a provider.
