Get yourself a 457 number
A 457 number is available through two routes. A provider assigns a new number with its plan. At sign-up, the number is chosen from those the provider holds in the code. Numbers already held by a seller are listed for a one-time price, often with a pattern. Afterward, you move the number to a provider.
