A2P (Application-to-Person) SMS Messaging
The process of sending mobile messages from an application to a mobile user. A2P SMS messaging is also called enterprise or professional SMS. Businesses can use it in several technical modes to communicate with consumers, authenticate users of online services, or deliver time-sensitive alerts. In all the cases, communication is initiated from a business application, and not an individual’s mobile phone, as is the case with P2P SMS.
Typical examples of A2P SMS include banking notifications, critical alerts, SMS-based two factor authentication, automatic booking confirmations, loyalty programs and marketing notifications etc. Online reservation systems, different corporate platforms and support services have deployed A2P SMS to increase efficiency and improve communication.
Financial institutions have been using A2P SMS for over 15 years, by delivering automated, event-based SMS notifications to their clients’ mobile phones. Examples include anti-fraud alerts, balance statements, payment reminders, withdrawal notifications.
The most popular modes of using A2P messaging are SMS API integration, access via a web interface (by obtaining a username and password), or the deployment of a professional enterprise solution.
