What Is A2P Messaging? How It Works and Why Businesses Use It

Have you ever received a text confirming your appointment, purchase, or a security code to log in? That’s A2P SMS. A2P messaging stands for Application-to-Person messaging, which businesses use to send automated messages to their customers via SMS software. A2P text messaging enables businesses to reach their customers at scale via SMS to increase engagement and ROI. 

Below, we’ll cover what A2P 10DLC messaging is, how it works, how to choose A2P messaging providers, and how using A2P SMS helps improve business communications.

TL;DR

• A2P (Application-to-Person) messaging is automated text messages sent by SMS software to customers, like OTPs, order updates, and appointment reminders.
• In A2P texting, messages are sent via an SMS gateway through your carrier to the recipient’s device. 
• Sender types include short codes, toll-free, and 10DLC numbers.
• A2P is built for scale, automation, and compliance.
• A2P text messaging offers fast delivery, wide reach, automation, and easy third-party integration.

What is A2P Messaging?

A2P messaging (Application-to-Person) is the automated text message (SMS/MMS/RCS) that is sent by software to a person’s mobile device instead of being typed manually by one human to another. 

Usually, businesses use it for transactional and promotional communications. A2P text messages are unidirectional and limited to commercial communication between enterprises and customers. 

A few examples of A2P SMS are two-factor authentication codes, OTPs, promotional alerts, reminders, automated booking confirmation, and more. 

What is P2P Messaging?

P2P Messaging (Person-to-Person texting) is the exchange of SMS between two individuals. For example, when you send a message to your friend from your personal phone, it is a P2P message.

One question will pop into your mind: Can’t businesses use P2P messaging to send business texts instead of relying on SMS software?

The simple answer to this is NO, because texting customers without a software application becomes disorganized. Teams can’t see each other’s messages, track resolved conversations, or automatically process opt-out requests. All these are crucial for efficient business communication and compliance.

Carriers now require businesses to register their phone numbers under 10DLC before using them for business texting. Additionally, the 10DLC registration can be a lengthy and tedious process without an SMS provider.

We also recommend reading our latest blog on 10DLC brand vetting and how it affects SMS marketing to get the most out of your SMS campaign. 

In the next section, we’ll compare A2P and P2P messaging side by side to help you better understand the two.

A2P and P2P Messaging Quick Comparison

A2P and P2P messages arrive in the same SMS inbox, but they’re created and delivered differently.

How Does A2P Text Messaging Work?

There are mainly four steps involved when you send A2P messages, whether in bulk or as an individual message ( SMS or MMS ) using your SMS marketing platform. 

• First, your message is delivered to an SMS gateway.
• An SMS gateway enables your SMS platform to communicate with mobile devices via a cellular network.
• The SMS gateway connects the SMS application with the mobile network operator to ensure the message reaches the correct recipient’s mobile phone.
• The recipient’s phone displays the message, and at this point, the message is considered successfully delivered.

Latest Updates About the Meaning of A2P Messaging

Until recently, A2P messaging was primarily associated with mass texts or automated text messages, such as automated reminders, shopping notifications, one-time passwords, and two-factor authentication. 

However, in 2019, the CTIA (Cellular Telecommunications Industry Association) released an update on A2P text messaging, outlining key messaging principles and best practices for the industry.

In that update, CTIA clarified that P2P messaging must be strictly between two consumers. People who act on behalf of businesses or organizations are not considered consumers. It widened the definition of A2P messaging.

What are the types of A2P Messaging?

Not every A2P message serves the same purpose. Some messages help customers complete their transactions or receive some important updates, while some messages are solely intended to promote products, services, or events. It is important to understand both because carriers and regulators often apply different rules to each category.

1. Informational A2P Messaging

Informational messages provide valuable updates to customers and help build a strong relationship with them. These messages are typically triggered by a user action, account event, or business procedure. Some common examples of informational A2P messages are one-time passwords, billing notifications, shipping updates, and order confirmations. The main purpose of this type of message is to notify, promote, or assist the recipient instead of promoting a product or service. 

2. Promotional A2P Messaging

The main aim of promotional A2P messages is to spread awareness, drive engagement, and boost sales. Businesses typically use them to encourage customers to take specific action, such as purchasing a product, attending an event, or redeeming an offer. Some common examples of A2P text messages are product launch announcements, event promotions, coupons and discount offers, and more.

What are the Sender Types of A2P Messaging?

You must be wondering which type of number a business should use for A2P messaging. It is important to know because the type of number you use for A2P texting affects compliance and deliverability. 

1. 10DLC Numbers

10DLC numbers are 10-digit phone numbers that look like standard personal phone numbers but are designed for business texting. This number option is best for businesses that send A2P messages. These messages offer better deliverability and high throughput than traditional long codes during mass texting.

2. Toll-Free Numbers

Toll-free numbers are numbers that use familiar prefixes like 800, 888, 877, 866, 844, and 833. These numbers support both voice and text communication and are free for the caller to use. For businesses that want customers to reply quickly, toll-free numbers are the best option.

3. Short Codes

Short codes are 5- to 6-digit numbers that are specifically designed for high-volume messaging. They are ideal for time-sensitive campaigns, large-scale promotions, and situations where a memorable, easy-to-use number is beneficial. 

Apart from these, you also need an EIN for A2P registration and A2P text messaging. If you want to learn more about which businesses require an EIN and which ones need a DUNS number, check our latest guide on DUNS number vs EIN.
