How does 10DLC registration work?

10DLC registration happens in two stages: you register your brand, then you register each campaign. Brand registration submits your legal business identity, legal name, EIN, address, and website, so the carriers know who is actually sending. Campaign registration describes one specific use case, what you will send, how often, and how people opt in, with sample messages and your opt-in evidence. Once both are approved, the carriers assign throughput and your traffic is treated as sanctioned rather than suspicious. Brand approval is usually quick, often the same day. Campaign vetting typically takes a few business days, and longer for regulated or higher-risk use cases.

How 10DLC Registration Works, Step by Step

The part businesses underestimate is the opt-in evidence. Carriers want to see the actual consent flow: the web form with its checkbox and disclosure, the keyword instructions, or the paper form wording. A campaign is far more likely to be rejected for vague or missing opt-in proof than for anything technical. Screenshots of a real, live consent flow are the single best thing you can prepare in advance.

Registration also produces a trust score, which is what actually governs your daily message throughput. A verified business with a clean EIN match and a well-described campaign scores higher and can send more per day. A thin or mismatched brand record scores lower and gets throttled, regardless of how good the messages are.
