In this comprehensive guide, we'll walk you through the most important things to know when registering for A2P 10DLC, so you can make the most of your SMS communications while staying compliant with industry regulations.

1. Understanding A2P 10DLC

A2P 10DLC stands for Application-to-Person 10-Digit Long Code. It is a process that authenticates your business identity and enables you to send SMS messages to customers in a secure and trusted manner.

3. Benefits of A2P 10DLC:

Additionally, A2P 10DLC enhances your brand reputation by clearly identifying your business as the sender, fostering trust and credibility among your audience.

It's also important to accurately register the volume of messages your send with your use case, and to describe the opt-in methods used to collect your list of contacts to ensure you are following CTIA messaging best practices.
