Registering 10DLC numbers for SMS campaigns

Introduction

10DLC stands for 10-digit Long Code. 10DLC messaging lets businesses send sanctioned Application-to-Person (A2P) messaging traffic (campaigns) over local phone numbers, also known as "long codes".

SMS messaging is not regulated by the FCC, leaving individual carriers responsible for preventing spam and malicious activity. As messaging volumes continue to grow, carriers are tightening regulations on A2P campaigns by adjusting throughput limits and enforcing new registration requirements and fees. Throughput limits vary, but businesses registered for campaigns are expected to receive better throughput than the traditional rate of one message per second (MPS).

To send SMS campaigns through 10DLC, businesses are required to register their numbers. This helps carriers identify legitimate messaging traffic and ensures compliance with regulations, reducing spam and improving delivery rates while maintaining the security of customer interactions.
