What is 10DLC and When Do Businesses Need to Use It?


All major wireless carriers in the U.S. have adopted the new 10DLC numbers standard for A2P long code messaging. As the approved solution for A2P messaging, the 10DLC standard is designed to deliver a better customer experience with business benefits such as brand accountability and more reliable SMS delivery.
