A2P Messaging: Definition, How It Works, Process and Who Uses It

A2P messaging, or enterprise or business SMS, is a messaging technique where businesses send texts from a software application to a consumer’s device. Users opt-in to receive text message notifications and can interact with companies through their mobile network connection. A2P messaging is typically a one-way communication, meaning the recipient doesn’t need to respond.

A2P messaging is a great way for businesses to engage with consumers because receivers open around 98% of all text messages. These messages include marketing campaigns, promotional codes, appointment reminders, account pin codes, bank alerts, and shipping notifications. Various industries such as retail, banking, telecom, healthcare, and travel have already adopted A2P technology. This article will discuss what A2P messaging is, how it works, and what industries use it.

What is A2P Messaging?

A2P messaging refers to messages that a person receives from an application instead of an individual. These messages are not meant to be replied to and can include marketing communications, appointment reminders, chatbots, notifications, one-time passwords (OTPs), or PIN codes. Messaging application platforms are considered A2P by carriers in the US and Canada, so they strictly interpret what qualifies as such.

Application to Person messaging is different from Person to Person. If you receive an SMS message from your friend, it is a P2P type of messaging. But when a business sends you a message, it is likely generated by an application, not a person. This type of messaging is called Application to Person messaging or A2P messaging.

A2P messaging, also known as Business SMS or enterprise SMS, enables the execution of various forms of texting, such as Group Texting, Broadcast messaging, MMS Group messaging, Automated texting, and more.

How Does A2P Messaging Work?

A2P messaging involves using the Short Message Peer-to-Peer Protocol (SMPP) to facilitate communication between entities. The SMPP manages the exchange of messages by regulating how the entities send and receive, and packaging them.

One entity will start an SMPP session using the SMPP to decide where it is delivering the message. Afterward, a Short Message Service Centre (SMSC) takes or declines the message and then forwards it to the other entity.

The A2P messaging also requires Internet of Things (IoT) devices that can be linked to wireless networks, just like cell phones. These IoT devices determine how the A2P messaging will connect messages to end-users. Most of today’s well-known IoT applications utilize cellular connectivity. They further use a software application by which they can communicate, like an SMS.

In the A2P work scheme, the SMSC works like a mediator because it decides their interactions and transmits messages. In contrast, the application functions as the extra mediator that brings messages to and from the SMS in the name of the IoT devices.

What is the Process of A2P Messaging?

The process of A2P messaging starts from the sender’s mobile phone. The messages will be sent from this number, and the carrier network will receive it. Then, the SMSC will receive and process the message. After processing, it will determine whether it is an A2P or P2P message.

The SMSC will then push the messages to its routing table to decide which carrier should get the message. The next step is for the carrier network to receive and send the messages to the recipient. Finally, the message will be received by the recipient’s mobile phone and opened or stored in their inbox.

To clarify, the SMS gateway or aggregator connects the texting software to the mobile carrier, such as T-Mobile or AT&T. The carrier then checks the message for spam and other unwanted content.

Who in Particular Uses A2P Messaging?

A2P messaging is used by businesses to communicate with customers or members of their organization. Companies that want to keep track of messages and send automated text messages use A2P messaging.

Registering your brand with the carrier before sending out any texts is essential to ensure that your messages will reach your customers without being blocked or filtered.
• Increased Risk of Spam – If your messages are not sent through an approved A2P messaging provider, there is a risk that they will be flagged as spam. It can result in customers unsubscribing or blocking future messages from your business.
• Increased Cost When Sending Messages Internationally – A2P messaging providers charge higher rates for international messages, making sending messages outside your country more expensive. It is essential to factor in this additional cost when using A2P messaging for global campaigns.

What are the Ways of conducting A2P Messaging?

There are three ways to conduct A2P messaging for businesses texting needs. Depending on the size and type of your business, one or all of these methods may be appropriate for you.

• 10 DLC or 10 Digit Long Code – These numbers are similar to those used for personal texting, giving customers a familiar experience. This method is often more affordable but may have slower delivery times and lower message throughput than other methods. To use 10DLC for A2P messaging, businesses must register with their carriers. By sending messages through a 10DLC number, companies can keep their phone number, and customers can receive and respond to messages from that number.
• Shortcodes – A shortcode is a number of 5 or 6 digits. It is utilized by businesses to send text messages to numerous people via a software program. In the past, this was the primary method used by companies to deliver large quantities of messages. Businesses may purchase a shortcode, but these numbers are sometimes shared with other firms. A dedicated shortcode is also costly, reaching over $500 per month. If you want to create an opt-in database, businesses often use shortcodes that work effectively. This way, they can filter the audience who wants to hear from them and start texting them from a 10DLC number to increase engagement.
• Toll-Free Numbers – You can also use toll-free numbers (TFN) for A2P texting. TFN A2P messages are suitable for medium-volume message broadcasts and provide a cost-effective and professional phone number option for messaging prospects and clients.

• Use Opt-Out Language – It is crucial to inform recipients that they can choose not to receive future messages from the sender. It is imperative when sending informational or promotional messages.
• Process HELP Commands – To make it easier for users, HELP commands or keywords must be included in messages to provide information about the sender and how to opt-out if needed. While they are not mandatory for toll-free messages, it is recommended to use them. The customer is responsible for managing HELP as there is no network-level processing.
• Use Single Domain URLs in Your Message – To ensure clarity, each campaign must have a unique web domain that belongs to the customer. You may use a custom URL shortener; however, avoiding using commonly used or publicly shared domain shorteners is essential.
• Process START and UNSTOP Keywords – To start receiving messages again from a sender, the consumer can text the keyword “UNSTOP” or “START” to the sender’s phone number. The keyword should be sent as a single word without punctuation or leading spaces. Trailing spaces will be removed, and the keyword is not case-sensitive.
• Process STOP Keywords – The consumer must opt out of messages by sending the keyword “STOP.” It should be sent as a single word without punctuation or leading spaces.

The message will follow the guidelines provided by the Cellular Telecommunications and Internet Association (CTIA), which require a single confirmation message that verifies the subscriber’s enrollment in the program and offers instructions to opt-out.
• Establish Brand Identity – When sending a message, it is vital to establish the brand identity of the sender. It is done by including a logo or other recognizable elements from your company in the messages. It also helps differentiate you from other senders and prevents your messages from being mistaken for spam.
