Get hold of a 504 number
Two paths bring you to a 504 number. A provider gives you a new number as part of its plan. You pick that number when you sign up, choosing from the pool of numbers the provider holds in the code. A seller puts numbers it already holds up for sale, often with a pattern, and charges a one-time price. You then move your number to a provider.
