You do not usually deal with TCR directly. Messaging providers are connected to it and submit on your behalf, which is why registration fees appear on a provider invoice rather than as a bill from TCR. What you supply is the underlying truth: an exact legal business name, a valid EIN that matches it, a real website, and an honest description of each campaign.
The most common failure is a mismatch. If the legal name on the brand record does not exactly match the EIN registration, vetting fails or the trust score drops, and a low trust score means throttled throughput. It is worth checking the legal name character for character before submitting, because correcting a record afterwards is slower than getting it right the first time.
- TCR is the shared registry the US carriers read; it holds brand records and campaign records.
- It issues the trust score that determines your daily throughput.
- Your messaging provider submits to TCR for you and passes the fees through.
- Exact legal name and matching EIN are the details that most often cause a failed or downgraded registration.
