Get your own San Francisco number
You can get a San Francisco number in two ways. Along with its plan, a provider assigns a new number. That choice is made at sign-up, using numbers the provider holds in the code. A seller posts numbers it already has, often with a pattern, at a one-time price, and then you take the number over to a provider.
