The Campaign Registry, usually called TCR, is the central body where businesses and campaigns register to send 10DLC texts. It sits between senders and the mobile carriers, collecting and vetting registration information so the carriers can decide whom to trust. If you send political texts on standard numbers, your registration runs through TCR, so it's worth knowing what it is and what it does.
What does The Campaign Registry do?
TCR is the clearinghouse for 10DLC registration. When you register your brand and campaign, that information goes to TCR, which vets it and passes it to the carriers, who use it to grant throughput and deliverability. In effect, TCR is the shared system that lets the whole ecosystem, many senders, many carriers, verify identities in one place rather than each carrier vetting each sender separately. It's infrastructure, and every legitimate A2P sender passes through it.
How does it fit between campaigns and carriers?
Think of it as the middle layer. The campaign registers with TCR; TCR vets and stores the registration; the carriers rely on TCR's records to decide how to treat the traffic. For political senders, Campaign Verify plugs into this flow, providing the political-identity proof that TCR and the carriers use to grant the political use case. So the path is: verify your committee, register through TCR, and the carriers deliver based on that registration.
Why does every political texter deal with TCR?
Because TCR is where 10DLC registration happens, and 10DLC is what makes texts deliverable. There's no way around it for standard-number A2P sending, unregistered traffic gets filtered, and registration means TCR. You may interact with it directly or through your texting platform, which handles the registration on your behalf, but either way your sender identity lives in TCR. Understanding that helps demystify why registration takes the steps it does: you're being entered into the shared system the whole industry trusts.
