Get your own 667 number
You can reach a 667 number by two routes. A provider assigns a new number with its plan. That number is picked when you sign up, out of 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 move your chosen number to a provider.
