Get your own 657 number
You can get a 657 number in two ways. A provider assigns a new number with its plan, and it is chosen at sign-up from the numbers it already holds in the code. Sellers list numbers they already hold, often with a pattern, at a one-time price. You then transfer your chosen number to a provider.
