(Updated May 2023)
If you’re a business wanting to send SMS, you may have come across acronyms like A2P and P2P. They can be a bit confusing and may sound like jargon. Yet understanding the differences between A2P and P2P is helpful for businesses.
Dive in to understand the best way to send messages for your business needs. If you are a visual learner, jump down to our handy infographic.
What application-to-person (A2P) means.
Application-To-Person (A2P) SMS refers to a software application, such as a mobile service provider, sending a message to mobile devices. An SMS gateway can send out thousands of messages per second to different phone numbers across the globe.
A2P messages are generally:
- One-way or two-way
- Automated or integrated into a CRM
- Conversational, informational, or transactional
According to a recent report, A2P SMS marketing is projected to reach $86.7B by 2027. Currently, the market is valued at an estimated $65.7B.
What person-to-person (P2P) means.
Person-to-Person or Peer-to-Peer SMS is a basic text message exchange between two people using mobile phones and SIM cards.
Think of it this way: these are messages we exchange with our friends, colleagues, and family. For example, this could be a simple text message we send to our mom to check-in on how she’s doing.
P2P messages are generally:
- Two-way
- Used by individuals, not for commercial use
- Conversational only
A2P SMS vs P2P SMS.
The significant difference between A2P and P2P messaging is often their purpose and send volume.
P2P messages are often used for personal reasons and between one sender and one recipient. A2P messages are often used for commercial or marketing purposes and can be sent to thousands of recipients at once.
Telecommunication providers built A2P SMS to allow for higher volume sends to meet large-scale business needs. Now that we know what these terms mean, let’s explore different ways to send A2P SMS.
