Sole Proprietor 10DLC
No EIN? Register as a Sole Proprietor brand: one number, low caps, full compliance duties. Upgrade to a standard brand when you incorporate.
Not every sender has an EIN. The Sole Proprietor brand type exists so freelancers, side businesses, and unincorporated operations can still register: identity is verified against personal details and a mobile number OTP instead of IRS records.
The trade-offs are strict: one phone number per campaign, the lowest throughput tier, T-Mobile daily caps around 1,000 message segments, and tighter content scrutiny. Some CSPs add their own volume limits on top.
Sole proprietor registration is a legitimate on-ramp, not a loophole — consent, disclosure, and STOP-handling requirements are identical. Once a business forms an entity and obtains an EIN, upgrading to a standard brand removes the caps.
