Application-to-Person (A2P) messaging

Application-to-Person (A2P) messaging refers to the process where an application sends messages to a mobile subscriber.

This form of messaging is widely used in various industries for a range of purposes. 

  • Automated Communication: A2P messaging is typically automated and involves sending texts from an application to an individual's mobile device. This contrasts with person-to-person (P2P) messaging, which involves two individuals texting each other.

  • Business and Informational Use: It's commonly used by businesses and organizations to send notifications, alerts, promotional content, reminders, and verification codes to customers or users. Examples include SMS messages for flight updates, banking alerts, appointment reminders, and one-time passwords (OTPs) for two-factor authentication.

  • High Reach and Engagement: Due to the widespread use of mobile phones, A2P messaging allows businesses to reach a large audience efficiently. SMS messages have a high open and read rate compared to emails.

  • Regulatory Compliance: A2P messaging is subject to regulatory compliance in many regions, ensuring that messages are not spammy and that recipients have opted in to receive these messages.

  • Use of Short Codes and Long Codes: A2P messages are often sent using short codes (short numerical codes assigned to a business) or long codes (standard phone numbers). Short codes are typically used for high-volume messaging.

A2P messaging has become an essential tool for businesses and organizations for direct and effective communication with their audience, offering both reliability and broad reach.
