Why This Rejection Happens
You are attempting to register a "Sole Proprietor" campaign type, but your Brand is registered as a formal entity (LLC, Inc., Corporation) OR your messaging provider (CSP) does not support Sole Prop registrations.
Root Cause Analysis
Entity Mismatch: Sole Proprietor campaigns are ONLY for individuals without an EIN (using a home address). If you have an EIN and registered as a Standard Brand, you CANNOT use the Sole Prop use case.
The Fix
You must select the correct campaign type for your business entity.
✓ Correct Path
Select "Low Volume Standard" or "Standard" campaign type. This matches your LLC/Corp status.
✗ Incorrect Path
Selecting "Sole Proprietor" to save money/time when you are actually an LLC.
