Application-to-Person (A2P) messaging has become the backbone of business-to-customer communication in the digital age. In the United States, 10-Digit Long Code (10DLC) messaging is now the primary channel for brands seeking to deliver high-volume, personalized notifications, alerts, and marketing messages in compliance with regulatory requirements. As we reach October 2025, the A2P 10DLC landscape continues to evolve rapidly, shaped by new industry guidelines, regulatory changes, and technological advancements.
