Understanding 10DLC for Resellers

Businesses that wish to offer SMS services to their end customers—without holding a direct relationship with The Campaign Registry (TCR) as a Campaign Service Provider (CSP)—are classified as Resellers in the messaging ecosystem.

Resellers can register brands and submit campaigns on behalf of their clients through the Sinch dashboard. However, it's important to note that Resellers cannot register themselves as the single brand and then associate multiple unrelated campaigns beneath it identifying different brands/customers.

Each campaign must be directly tied to the brand that will be represented in the messaging content. This ensures consistency and transparency across the ecosystem.

This alignment between brand and campaign is a mandatory requirement enforced by all major U.S. mobile carriers for sending registered A2P (Application-to-Person) messages.

Additionally, mobile carriers expect the content of the campaign to match the selected campaign use case. Campaigns cannot have multiple use cases under a single use case. Please see the attached list of campaign use cases and their descriptions: 10DLC Use Cases

To ensure first time approval, please review the linked articles below which outline US 10DLC Requirements and how to address Rejections:
