What is A2P 10DLC
Any sort of traffic in which a person is receiving messages from an application is known as A2P, or application-to-person messaging. Marketing messages, appointment reminders, chatbots or virtual assistants, notifications, and one-time passwords (OTPs) or PIN numbers are just a few examples of A2P messaging.
10DLC (10-digit long code), is the service that specifically permits application-to-person (A2P) SMS traffic over long code phone numbers. Standard US local phone numbers, which are 10 digits long (including the area code), are referred to as "10-digit long codes."
Why am I required to register
Starting March 1, 2023 US carriers require that all companies register their 10DLC number(s) and the campaigns they use them for in order to establish this authorized channel. It's the carriers' method of ensuring that SMS remains a viable medium of communication when more companies, like yours, start messaging customers. By registering 10DLC numbers, it reduces spam likely notifications and improves deliverability, which will ultimately raise the credibility of your own messages with clients.
The registration pocess below should take about 5 minutes to complete and you shouldn't suffer any downtime after completing the registration form.
