Understanding A2P 10DLC: Enhancing SMS communication with Mixmax

At Mixmax, we value effective and reliable communication. Our SMS feature helps you to engage with your prospects and customers through text messages.

To ensure that your SMS messages reach your audience consistently, you must register for A2P 10DLC (Application-to-Person messaging via 10-Digit Long Code phone numbers) and obtain campaign approval before being granted access to the SMS feature.

This article will help you understand how A2P 10DLC works and why it's crucial for your SMS communication. You will also learn what information you need to provide when registering for A2P 10DLC via Mixmax.

What is A2P 10DLC, and why is it important?

A2P 10DLC is a framework introduced by mobile carriers to regulate and optimize Application-to-Person (A2P) SMS traffic. It standardizes the use of 10-digit long codes for commercial messaging, helping to improve message deliverability, reduce spam, and enhance the overall user experience.

A2P 10DLC offers several significant benefits for your SMS communication:

  1. Improved Deliverability: When you get registered for A2P 10DLC, your messages are more likely to reach your intended recipients. Carriers prioritize approved A2P 10DLC traffic, ensuring higher message delivery rates than unregistered or non-compliant numbers.

  2. Increased Trust and Reputation: A2P 10DLC helps build trust with mobile carriers and their subscribers. Complying with registration requirements shows your commitment to delivering legitimate and valuable messages. This can benefit your reputation as a reliable sender.

  3. Compliance with Regulations: A2P 10DLC registration ensures compliance with industry regulations and guidelines, such as the CTIA Messaging Principles and the Telephone Consumer Protection Act (TCPA). It helps protect consumers from unwanted or fraudulent messages and ensures you adhere to best practices for SMS communication.

Best practices for A2P 10DLC

To make the most of A2P 10DLC and ensure successful SMS communication, consider the following best practices:

Explicit Consent

Always obtain explicit consent from your recipients before sending them SMS messages. Implement transparent opt-in processes and provide opt-out instructions for easy unsubscribing.

Message Content

Craft concise, engaging, and relevant messages that provide value to your recipients. Avoid using misleading or spammy content that might lead to complaints or delivery issues.

Message Frequency

Respect your audience's preferences and avoid excessive message frequency. Find a balance that keeps your audience informed without overwhelming them.

Compliance

Familiarize yourself with applicable regulations and guidelines, such as the CTIA Messaging Principles and the TCPA, and ensure your campaigns adhere to them.
