A2P – application-to-person messaging

A2P, or application-to-person messaging, is any kind of traffic in which a person is receiving messages from an application. A2P messaging includes (but is not limited to) marketing messages, appointment reminders, chat bots or virtual assistants, notifications, and one-time passwords (OTPs) or PIN codes.

A2P messages can be subject to local country regulations (e.g. France and India). These restrictions can have delivery implications that customers should be aware of, such as message filtering by recipient carriers or delayed message delivery.
