Telnyx opens 10DLC registration to sole proprietors

Customers without a federal Tax ID (EIN) can now register for 10DLC messaging through the new Sole Proprietor brand type. Freelancers, small business owners, and individuals can complete registration directly in the Telnyx Mission Control Portal or via API, with a simplified data collection flow that removes the EIN requirement.

What's New

A new Sole Proprietor brand entity type is now available in both the Portal and API. Instead of requiring an EIN and full business documentation, sole proprietors provide personal information, address, mobile phone number, and the last four digits of their SSN or SIN. Identity is confirmed through a TCR-mandated OTP verification flow, where registrants receive an SMS PIN and have a 24-hour window to complete verification.

Key Benefits

• 10DLC access without an EIN: Freelancers, sole proprietors, and individuals can now register for 10DLC messaging without needing a federal Tax ID or formal business entity.
• Simplified registration: Streamlined data collection means faster onboarding with fewer fields to complete.
• Secure identity verification: OTP verification via SMS PIN ensures compliance with TCR requirements while keeping the process simple.
• Built-in guardrails: Sole proprietor brands are limited to one campaign and one phone number, with low-volume throughput and mobile reuse prevention (max three brands per mobile number) to maintain ecosystem trust.
