Why are there phone number based rate limits?

Traditionally, local numbers were only used in P2P use cases, which are intended for conversational traffic and expected to be consistent with human operation as defined in the Cellular Telecommunications and Internet Association (CTIA) Messaging Principles and Best Practices which is why the per number rate limit was typically set at 1mps. As more carriers announce sanctioned 10DLC A2P programs, we will likely see this limitation change. Another thing to keep in mind is that the account level rate limit will trump the per TN rate limit so the account level rate limit is more important to focus on.
