Is your business a direct brand, or an ISV?

This article provides a quick overview of direct vs. ISV-type customers. For a more detailed description, see Am I a direct customer or an ISV (for A2P 10DLC registration)?

Direct brand

Your company sends messages for your own products and services. For example, you are Shoe Company A and you send messages related to your products, order updates, etc.

Independent Software Vendor (ISV)

Your company provides messaging services to other businesses, who have their own brands. For example, a company that provides communication services to hair salons or hotels is an ISV.
