TCR uses a reputation algorithm to assign your business a Trust Score. Your Trust Score level, (Low, Medium or High), combined with your Campaign Type will determine the message throughput allotted to your Campaign.

Once my Brand and Campaign have been registered with the TRC, how can I make sure my phone numbers use 10DLC?
After your Brand(s) and Campaign(s) are approved, please ensure that your inbound message configuration (e.g. the webhook for your application) is applied on your Messaging Service. Currently, the inbound configuration settings of a Messaging Service takes precedence over the existing inbound settings on those numbers.
Do I need to use a different method to send outbound messages?

To associate phone numbers to a Campaign, you only need to add phone numbers to a Messaging Service.
