Get hold of a 512 number
Two paths lead to a 512 number. New numbers come with a provider plan, and the one assigned is picked at sign-up from the numbers that provider holds in the code. Numbers a seller already holds are listed for sale, often with a pattern, at a one-time price; afterwards you transfer the number to a provider.
