MESSAGING

CASE STUDY
Shifting regulations. Bottlenecks stalling campaign rollout. 10DLC was holding Commio’s business back. But in partnership with Syniverse, it became a strength: slashing approval times to 30 minutes, boosting campaign success to 80%. Messages sent to junk? Less than 1%. Here’s how our pre-vetting and compliance expertise kept their customers’ critical messages flowing, fast.
The fact that we have access to a dedicated team at Syniverse is the reason we’re still here.
10DLC stands for 10-Digit Long Code, a standard phone number used for Application-to-Person (A2P) messaging, allowing businesses to send SMS/MMS to customers via a local, recognizable number with enhanced deliverability and compliance.
Non-compliance can result in increased fees, message filtering, or fines. For instance, T-Mobile will impose fines for sending non-compliant traffic. Therefore, it is vital to utilize our Professional Services team for guidance on how to best achieve compliance when setting up your campaign.
A campaign service provider (CSP) must be registered with The Campaign Registry and then must register their brands with The Campaign Registry (TCR) and submit campaign use cases. Syniverse simplifies this process by guiding customers through campaign registration and campaign approval, and connecting customers directly with TCR.
Depending on complexity, many campaigns are approved within hours (paid service). For regulated industries or MMS-heavy campaigns, allow 1–3 days.
Major U.S. mobile carriers (e.g., AT&T, Verizon, T-Mobile) enforce 10DLC compliance. The Campaign Registry (TCR) manages registration and vetting, and is supported by campaign service providers (CSPs) like Syniverse.
10DLC is not a law but an industry standard enforced by U.S. carriers, complementing legal frameworks like the Telephone Consumer Protection Act (TCPA), which requires consumer consent for messaging.
To register a 10DLC, provide your business’s legal name, EIN, address, website, and campaign use case to a campaign service providers (like Syniverse), which submits the details to The Campaign Registry for brand and campaign verification.
