A2P SMS

A2P SMS (Application-to-Person SMS) is a type of message sent from an automated system, application or server to a user. Unlike traditional messages that are sent from one person to another (P2P), A2P messages are initiated by businesses, government agencies or various services to send out information in bulk. This type of messaging is widely used for notifications, marketing campaigns, transactional messages, confirmations and two-factor authentication.

A2P SMS plays an important role in today's digital interactions, providing companies and organizations with a convenient and efficient channel to communicate with customers. These messages are delivered directly to users' cell phones, providing a high probability of being read, making this channel one of the most effective in communications.

In what cases is A2P used?

A2P SMS is used in a variety of situations where bulk messaging from a company or service to a user is required. The main A2P SMS use cases include:

1. Transactional messages: A2P is used to send transaction confirmations, such as notifications of payments, money transfers or purchases. It is an important part of the customer experience in online banking and e-commerce.
2. Two-Factor Authentication (2FA): A2P SMS is often used to send one-time confirmation (OTP) codes needed to increase security for accessing online services.
3. Notifications and reminders: companies use A2P to send various notifications and reminders such as alerts about appointments, schedule changes, delivery status, etc.
4. Marketing campaigns: A2P SMS is actively used in marketing to send promotional messages, discount offers, promotions and other marketing initiatives to attract customers.
5. Public service alerts: government agencies also use A2P to send emergency notifications, emergency alerts or administrative notifications.

How is P2P different from A2P?

The main difference between P2P (Person-to-Person) and A2P (Application-to-Person) SMS is the source of the messages sent and their purpose.

Message Source

P2P SMS are messages that are sent from one user to another. For example, when two people exchange text messages through their cell phones. In this case, the message is manually initiated and the sender is always the person.

A2P SMS, on the other hand, is initiated by an automated system or application. The message is sent from the business or service to the user. In this case, messages are created automatically in response to specific user actions or as part of a pre-scheduled mailing.

Volume and frequency

P2P messages are typically sent in smaller volumes and with irregular frequency. They are typical messages sent by users to communicate with each other, and their sending is limited by the capabilities of a single device.

A2P messages, on the other hand, are sent in bulk, often as part of large mailings or systematic notifications. Such messages can reach thousands or even millions of users simultaneously.

Purpose

P2P SMS are intended for personal communication between users, whether they are friends, family or coworkers. These messages usually have no commercial context and are used for communication.

A2P SMS, on the other hand, is used for business-to-business and business-to-customer interactions. These messages have a clear purpose: informing, confirmation, marketing, alerts, etc.

Tariffs and infrastructure

Due to differences in volume and purpose, P2P and A2P SMS are charged differently. Telecom operators usually apply special tariffs for A2P messages, as their bulk sending requires a different infrastructure and supports specific data transmission conditions.
