Messaging Compliance
Last updated: March 18, 2026
Why Compliance Matters
US and Canadian wireless carriers require all businesses sending application-to-person (A2P) SMS messages to register their phone numbers under the 10-Digit Long Code (10DLC) framework. This registration ensures better deliverability, prevents messages from being blocked or flagged as spam, and demonstrates your commitment to responsible messaging.
10DLC Registration
10DLC registration involves two components managed through The Campaign Registry (TCR):
- Brand Registration: Identifies who is sending the messages — your company name, EIN/business number, and contact information
- Campaign Registration: Describes what you are sending — the type of messages (e.g., appointment reminders, survey invitations, customer follow-ups) and sample content
EthnicPath Virtual handles the 10DLC registration process on your behalf. Contact us to get started.
Opt-In / Opt-Out Requirements
All SMS campaigns must comply with consent and opt-out regulations:
- Prior Consent: You must have documented consent from recipients before sending messages
- Opt-Out Mechanism: Every message must include a way for recipients to unsubscribe (e.g., “Reply STOP to opt out”)
- Opt-Out Honoring: Opt-out requests must be processed immediately — no further messages may be sent to that number
- Record Keeping: Maintain records of consent for compliance auditing
Applicable Regulations
- CASL (Canada's Anti-Spam Legislation) — Governs electronic messaging in Canada, requiring express or implied consent
- TCPA (Telephone Consumer Protection Act) — US federal law regulating telemarketing calls and SMS
- CTIA Guidelines — Industry best practices for A2P messaging
