A2P 10DLC Campaign Registration for US SMS
Short answer: SIP.IO is bringing A2P 10DLC Brand and Campaign registration directly into the platform, so US outbound SMS traffic gets registered, throughput-rated, and kept compliant without a separate carrier portal to manage.
Why this matters for US SMS
US carriers throttle or block application-to-person SMS sent over unregistered long-code numbers to control spam. Before you can send meaningful volume, you need:
- A registered Brand. Your company’s legal identity, verified against third-party business data, which sets your baseline trust score.
- A registered Campaign under that Brand, describing your specific use case (customer care, notifications, 2FA, marketing, and so on), your sample messages, and how recipients opted in.
- Numbers linked to that Campaign, which is what actually determines your throughput ceiling and deliverability with each carrier.
Skip registration, or register the wrong use case for your actual traffic, and carriers will throttle or filter your messages regardless of how clean your code is.
What’s coming to SIP.IO
- Brand and Campaign registration inside your account. No separate carrier or aggregator portal to log into just to get your SMS numbers sending.
- One place for the whole picture. Registration status, throughput tier, and your existing messaging channels managed together, not in two disconnected systems.
FAQ
What is A2P 10DLC registration? The US carrier framework for sending business SMS at scale over standard phone numbers: a Brand (your company) and one or more Campaigns (your use case) registered with The Campaign Registry, which carriers use to set throughput and filter unregistered traffic.
Why does US outbound SMS require this? Carriers throttle or block bulk A2P SMS over unregistered numbers to control spam. Registration identifies who’s sending, what, and how recipients opted in, raising your throughput ceiling and deliverability.
