Why does 10DLC exist?
Before 10DLC, businesses sent A2P SMS from regular long codes that were designed for person-to-person texting. Carriers couldn't tell legitimate business traffic from spam, so deliverability suffered and carriers throttled or blocked unregistered traffic.
10DLC introduced a registration model: every brand registers its identity, every messaging use case is registered as a campaign, and carriers grant throughput and trust accordingly. The result is reliable delivery for compliant senders.
Who needs to register for 10DLC?
Any business sending application-to-person SMS to US recipients from a 10-digit number needs to register. This includes lead follow-up, appointment reminders, transactional notifications, marketing, and two-way customer conversations.
Registration involves The Campaign Registry (TCR) — a brand record (your company) plus one or more campaigns (use cases). Carriers use these records to set throughput limits and validate consent practices.
