Pick up a 217 number
You can get a 217 number in two ways. A provider assigns a new number with its plan, and that number is picked at sign-up from the numbers the provider holds in the code. Sellers post numbers they already hold, often with a pattern, at a one-time price; you then transfer the number to a provider.
