10DLC (10-digit long code) is a carrier-approved messaging solution for Application-to-Person (A2P) messaging.
It enables businesses to send SMS and MMS using standard 10-digit phone numbers while ensuring higher deliverability, improved compliance, and faster throughput compared to unregistered long codes.
A registered 10DLC number is verified by carriers to meet industry compliance guidelines.
Registration significantly reduces the risk of filtering or blocked messages, ensuring your communications reliably reach customers.
