What is The Campaign Registry (TCR)?
The Campaign Registry is the central database where US businesses register their brand and messaging campaigns before carriers will deliver their A2P SMS traffic.
TCR sits between messaging providers and the carriers. Your provider submits your brand and campaign details, TCR vets them and assigns a trust score, then AT&T, T-Mobile, and Verizon apply their own review and throughput limits on top.
Registration carries one-time fees, per-campaign monthly fees, and per-message carrier surcharges that scale with volume.
