Introduction

In the era of instant communication, Application-to-Person (A2P) messaging has become the backbone of business communication. Whether it’s sending appointment reminders, authentication codes, or promotional offers, companies rely heavily on text messaging to connect with customers quickly and effectively. However, as the use of A2P messaging has grown, so has the need for regulation and compliance, and that’s where 10DLC compliance comes into play.
