10DLC Policy & Explainer
Provider: RingzU Telecommunications Corporation (including SMS/MMS/VoIP services used by all associated sub offerings of the Corporation and its affiliates.)
Summary: 10DLC (“10-Digit Long Code”) are standard local 10-digit numbers that U.S. businesses use for A2P (Application-to-Person) SMS/MMS. Registration with The Campaign Registry (TCR) and adherence to carrier/industry rules are required for compliant, reliable delivery.
1) 10DLC Explained
10DLC stands for 10-Digit Long Code, referring to standard, local, 10-digit phone numbers used by businesses in the U.S. to send A2P (Application-to-Person) SMS and MMS messages.
Key Aspects
- A2P messaging: Automated or bulk messages sent from software to individuals or groups.
- Purpose: Provide a more reliable, regulated channel than legacy, unregistered long codes to reduce spam.
- Registration required: Businesses must register their brand and campaigns with The Campaign Registry (TCR).
- TCR: Central database used by mobile carriers to manage/verify 10DLC campaigns.
- Registration process:
- Brand Registration — verifies business identity (legal name, EIN, address, website).
- Campaign Registration — defines use case (e.g., reminders, marketing), sample messages, and how opt-in consent is obtained.
- Benefits:
- Improved deliverability and reduced filtering vs. unregistered long codes.
- Higher throughput than P2P long codes (typically below short codes).
- Local-number trust and two-way messaging/voice on the same number.
- Cost-effective relative to dedicated short codes.
- Regulatory compliance; avoidance of penalties for unregistered messaging.
- Compliance is crucial: Follow CTIA guidelines; obtain explicit opt-in; provide opt-out (e.g., “STOP”) and HELP instructions; link to your Privacy Policy and Terms of Service.
- Alternatives: Short codes and toll-free numbers remain options, each with different costs, throughput, and use-case profiles.
In Essence
10DLC gives U.S. businesses a regulated, efficient way to send high-volume A2P messaging from local numbers, with better deliverability and customer engagement—provided you register with TCR and follow messaging rules.
2) Penalties for Non-Compliance
Non-compliance can trigger financial penalties, blocking, and reputational harm. Examples include:

- Messaging program evasion(e.g., “snowshoeing,” number recycling): about $1,000 per violation.
- Tiered fines (e.g., T-Mobile examples):Tier 1 (phishing, smishing, social engineering) $2,000; Tier 2 (illegal content) $1,000; Tier 3 (other violations, including SHAFT) $500.
- Non-use obligations:Failure to have at least one LVN associated with a 10DLC campaign in TCR can lead to monthly fines of $250.
- Carrier surcharges:Extra fees may apply to A2P traffic, especially at high volumes.
- TCPA lawsuits:The Telephone Consumer Protection Act allows statutory damages of $500–$1,500 per message for unsolicited texts.
- Fines:Carriers impose fines that can range from hundreds to thousands of dollars per violation. Examples:
