Why 10DLC Matters

The US A2P Messaging Standard

Since 2021, all A2P SMS sent over 10-digit long codes to US subscribers must be registered with The Campaign Registry (TCR). Unregistered traffic is filtered or blocked by all major US carriers (AT&T, T-Mobile, Verizon). Registered campaigns get higher throughput limits, better deliverability, and protection from spam filtering — making 10DLC registration essential for any US A2P SMS operation.

Features

10DLC Registration Platform

Brand Registration
Register your company as a brand with TCR via our dashboard. Provide EIN, legal business name, and contact details. TCR vets the brand and assigns a Brand ID with a trust score that influences throughput limits across all campaigns.
Campaign Submission
Submit use-case campaigns (2FA, marketing, account notifications, etc.) linked to your brand. Provide sample messages, opt-in workflow description, and help/stop keyword handling. Campaign vetting typically completes within 24-48 hours.
Number Assignment
Assign registered 10DLC numbers to approved campaigns via the dashboard or API. Numbers can be reassigned between campaigns, and the platform tracks which campaign each number is assigned to for carrier transparency reporting.
Compliance Monitoring
Automated monitoring detects opt-out keywords (STOP, QUIT, UNSUBSCRIBE) and enforces immediate suppression. Content scanning flags messages that violate campaign use-case descriptions or carrier content policies before they are sent.
Throughput Management
Track campaign throughput limits per carrier and per campaign. The platform automatically throttles sending to stay within approved Message Per Day (MPD) limits, preventing carrier filtering that results from limit violations.
Audit Trail
Complete audit log of all registration actions, campaign changes, opt-out events, and carrier appeals. TCR-generated campaign status webhooks are logged and archived for regulatory audit responses and carrier dispute resolution.
