Definition: A sole proprietor brand is a 10DLC brand type for US or Canadian individuals and small businesses without an EIN, limited to one campaign and one phone number.

This option exists so a freelancer or very small business can still text customers. The tradeoff is tight limits and less flexibility than a standard brand.

What are the sole proprietor limits?

What else should I know?

• Review speed. Twilio says sole proprietor campaigns are typically decided within hours to days.
• Provider support varies. Bandwidth says sole proprietor campaigns are auto-rejected on its network. Check with your provider first.
• Fees. Vonage lists a $2 monthly campaign fee for Sole Proprietor.
• Links. Twilio says embedded links must relate to your use case.

Why it matters for your website

Vonage made a website required for all brands except sole proprietors in 2025, so a site may not be mandatory for you there. Still, reviewers check how people opt in, and a clear site with SMS terms and a privacy policy makes that easy to show. See the 10DLC website requirements.
