If your business is sending application-to-person (A2P) text messages using 10-digit long code (10DLC) numbers in the US, you're required to register for 10DLC in order to avoid fees and penalties from mobile network operators. In this guide, we'll show you how to complete the second step of this process by registering campaigns, using tools provided in the Telnyx Mission Control Portal.


Every campaign must be associated with a brand. If you haven't already registered your brand, you'll need to do that before you can activate a campaign and send messages. Follow this guide to complete this first step before moving onto creating a campaign.

Additionally, you will want to ensure that your brand has a good Trust Score, as A2P 10DLC message throughput is determined based on your Trust Score and your Campaign Use Case. Learn more on throughput and Trust Scores in this article.

Creating a 10DLC campaign in the Mission Control Portal
