A2P 10DLC
A2P 10DLC is the U.S. framework for sending Application-to-Person text messages over standard 10-digit long-code numbers. Carriers require businesses to register their brand and campaigns (use cases) to send A2P SMS legitimately, with throughput and trust scores tied to that registration.
How it works
You register your business (brand) and each messaging use case (campaign) with The Campaign Registry via your provider. Approved registrations unlock higher throughput and lower filtering.
Why it matters
Unregistered A2P traffic on 10DLC is heavily filtered or blocked by U.S. carriers. Registration is the difference between SMS that delivers and SMS that silently disappears.
How Autocloz handles it
Autocloz's SMS channel is built for registered A2P sending with opt-in capture, STOP handling and quiet-hours/DNC gating, so business texting stays within carrier and TCPA rules.
FAQ
Do I need 10DLC registration for business texting?
Yes, for A2P SMS to U.S. numbers over long codes. Without brand and campaign registration, your messages face aggressive carrier filtering and blocking.

The TCPA is a U.S. federal law that restricts telemarketing calls, autodialed and prerecorded calls, and unsolicited texts. It requires prior consent for certain contact, honors the Do-Not-Call registry, and enforces calling-time windows — with statutory damages per violation that make compliance a real financial risk.
A Do-Not-Contact (or Do-Not-Call) list is a record of people who have opted out of your outreach — or registered on a government DNC registry — whom you must not contact again. Honoring it is both a legal requirement (TCPA, GDPR, CAN-SPAM) and a deliverability/reputation safeguard.
DLT (Distributed Ledger Technology) registration is India's TRAI-mandated framework for commercial SMS. Businesses must register as an entity, register sender IDs (headers) and message templates on a DLT platform, and only send pre-approved content — otherwise messages are blocked.
Cold email deliverability is the share of your outbound cold emails that actually reach the recipient's inbox (not spam, not blocked). It depends on domain authentication (SPF, DKIM, DMARC), sender reputation, mailbox warmup, list hygiene and content — not just whether the email was 'sent'.
