Techopedia Explains A2P Messaging

A2P messaging is commonly used for many key business practices such as multifactor authentication, as well as routine updates and notifications related to products and services. However, in the context of A2P messaging, intent can become difficult to assess. Companies might start out offering informative notifications, but then ask users to confirm something, or send a return text to buy into some program or service. However, in general many types of A2P are one-way communications and do not allow an individual user response. The opposite of A2P messaging, P2A messaging, allows for individual smartphone holders to message an enterprise directly.
