Section 2: Brand Registration Requirements
To register a brand successfully:
- U.S. Companies: Use your EIN (Employer Identification Number) and ensure it matches your Legal Company Name exactly as registered with the IRS (CP 575 or 147c letter).
- International Companies: Provide a valid Tax ID or equivalent business registration number from your country.
- Canada: Use the 9-digit Business Number (BN-9) from CRA.
- Avoid: Using DUNS numbers, trade names, SSNs, or mismatched names — these will result in rejections.
Pro Tip: Match your brand name, business website, and sample messaging consistently.
Section 3: Campaign Registration Requirements
Each messaging campaign must have:
- Clear Use Case Description — Who sends messages, who receives them, and why.
- Sample Messages — Must include:
- Your business name
- Templated fields (e.g., [Customer Name])
- Opt-out instructions (e.g., “Reply STOP to unsubscribe”)
- Your business name
- Opt-in Method — Required before sending messages. Acceptable formats:
- Web form (checkbox must not be preselected)
- Paper form
- Text keyword (e.g., “JOIN”)
- QR code linked to form
- Verbal (with documentation)
- Web form (checkbox must not be preselected)

Section 4: Best Practices for Approval
- Ensure all data is accurate: business name, website, EIN, and opt-in message.
- Maintain consistency across brand details and messaging.
