Get an 813 number
You can get an 813 number in two ways. A provider assigns a new number with its plan. At sign-up, that number is selected from the numbers the provider holds in the code. A seller advertises numbers already in its possession, often with a pattern, at a one-time price. You then transfer your chosen number to a provider.
