What is 10DLC Compliance?
10-Digit Long Code Compliance
10DLC compliance refers to following carrier regulations for sending business SMS messages using standard 10-digit phone numbers. Organizations must register their brand and messaging campaigns with The Campaign Registry (TCR) to send A2P (Application-to-Person) text messages without filtering or blocking.
10DLC Registration Requirements
To send compliant business SMS, you must:
- Register your brand — Company information verified with TCR
- Register campaigns — Describe each use case (alerts, marketing, etc.)
- Update Terms of Service — Include SMS consent language
- Update Privacy Policy — Describe how phone numbers are used
- Maintain opt-in records — Document consent for each recipient
Why 10DLC Matters
Non-compliant messages get filtered, delayed, or blocked by carriers. Registered 10DLC campaigns have higher throughput limits and better delivery rates than unregistered numbers.
