Understanding 10DLC Registration & Compliance Requirements
What is 10DLC
10DLC stands for "10-Digit Long Code." It is the carrier-approved system for businesses to send Application-to-Person (A2P) text messages using standard local phone numbers. Major U.S. mobile carriers (AT&T, Verizon, T-Mobile, etc.) require businesses to register their brand and messaging campaigns before sending SMS traffic over local numbers.
Why is 10DLC Required?
10DLC was implemented to reduce spam, protect consumers, and ensure transparency in business messaging. Carriers now require all businesses sending text messages through local numbers to complete brand and campaign registration through The Campaign Registry (TCR).
• Verifies that a legitimate business is sending messages.
• Ensures proper opt-in consent is collected.
• Reduces spam and fraudulent messaging.
• Improves message deliverability and throughput.
• Provides accountability for message content and practices.
Why Are Privacy Policies & Terms Required?
As part of 10DLC vetting, carriers require businesses to maintain publicly accessible Privacy Policy and Terms of Service documents. This applies even if texting is intended for internal employee communications only.
• Explain how phone numbers and personal data are collected and stored.
• Describe how messaging consent is obtained.
• Outline message frequency expectations.
• Disclose that message and data rates may apply.
• Provide instructions for opting out (e.g., Reply STOP to unsubscribe).
Carriers require these documents to be publicly accessible on the organization’s website so they can verify transparency and compliance during campaign review.
What is Opt-In?
Opt-in refers to the process by which an individual provides explicit consent to receive text messages from a business. Consent must be clear, documented, and voluntary.
• Signed written consent (physical or digital form).
• Employee handbook acknowledgment for internal messaging.
• Web form submission with clear SMS disclosure language.
• Texting a keyword to initiate enrollment.
Opt-in records must be retained and made available if requested by carriers or regulators.
Internal Employee Messaging Clarification
Even when SMS is used strictly for internal employee communications, carriers apply the same compliance standards. This ensures consistent data protection, transparency, and consent practices across all business messaging.
Summary
10DLC registration is not optional for businesses sending SMS through local numbers. Maintaining publicly accessible Privacy Policy and Terms documents, defining opt-in clearly, and following carrier guidelines helps ensure message deliverability and protects your organization from carrier filtering or campaign rejection.
