A2P Messaging (Application-to-Person Messaging), sometimes called business SMS or enterprise SMS, refers to SMS or MMS messages sent from a business to a person. Unlike P2P (Person-to-Person/Peer-to-Peer) messaging, A2P Messaging allows businesses to automate text messaging for appointment reminders, two-factor authentication, text message alerts, text based sales promotions, and more. With A2P messaging, businesses can also power functionality like conversation tracking within a CRM, multi-channel support conversations, and personalized marketing outreach.
There are 3 types of A2P Messaging based on what kind of phone number the messages are sent from: toll-free messaging, 10 digit long code (10DLC), and short codes. Each type has different implications for cost, functionality, and deliverability.
