Definition: The Campaign Registry (TCR) is the registry where Campaign Service Providers register the brands and messaging campaigns that send A2P texts over US 10DLC numbers.
Think of TCR as a shared record book. It stores who is sending (the brand) and what they plan to send (the campaign). Carriers and their partners use that record when they decide how to handle your traffic.
TCR's October 2025 user guide names these roles:
| Role | What it does |
|---|---|
| Brand | the company the end customer believes is sending the message |
| CSP (Campaign Service Provider) | registers brands and campaigns for businesses |
| CNP (Connectivity Partner) | connects CSPs and carriers |
| DCA (Direct Connect Aggregator) | connects directly to carrier gateways |
| MNO (carrier) | a mobile network, such as AT&T or T-Mobile |
TCR notes that privacy policy and terms link fields are optional in TCR itself, but having a compliant privacy policy and terms is still required. Twilio adds that TCR runs automated website verification with a screenshot.
The website field on your brand is where reviewers look first. TCR's guide calls filling it "strongly recommended," and Vonage made it required for non-sole-proprietor brands in 2025. Make sure your site matches your brand; see brand name match.
