What is 10DLC?

10DLC stands for 10-Digit Long Code, and simply refers to a ten digit phone number. As text messaging and the telecommunications industry has evolved, business are now able to use these 10-digit numbers to send and receive text messages with consumers.

Mobile carriers (such as AT&T, T-Mobile, Verizon Wireless, US Cellular, ClearSky, and Interop) have implemented new regulations that require all businesses to complete a 10DLC registration to continue sending SMS messages.

All CallHarbor customers who would like to send and receive text messages with their CallHarbor phone numbers will need to complete a 10DLC registration.
