Sole Proprietor Mismatch

Why This Rejection Happens

You registered as a "Sole Proprietor" (using a personal name) but the vetting data suggests you are actually a formal business entity (LLC or Inc) or provided an EIN. Alternatively, the name provided does not match the owner of the mobile number used for OTP verification.

• Providing a Business Name (e.g., "Joe's Plumbing") in the First/Last Name fields.
• Entering an EIN when the entity type is Sole Proprietor (use Standard Brand instead).
• Address provided does not match the personal address of the owner.

Root Cause Analysis

Primary Triggers

• Data Mismatch: Sole Prop registration requires a human name (First + Last). If you enter a company name, the identity check fails against credit bureau data.
• Entity Confusion: If you have an EIN, you are NOT a Sole Proprietor in the eyes of TCR v2. You are a Standard Brand. Sole Prop is reserved for individuals without tax IDs.

Step-by-Step Remediation

Check Entity Type

Do you have an EIN?
YES: Stop. Register as a "Standard Brand" (Low Volume).
NO: Continue as Sole Prop, but ensure you use your legal First and Last Name.

Correct the Name Field

In the registration form, change "Joe's Plumbing" to "Joseph Smith". You can use "Joe's Plumbing" as the *Brand* name later, but the *Legal Entity* must be the human owner.

Pre-Resubmission Checklist

• I used my personal legal name for the Entity Name.
• I used my personal home address (matching credit records).
• I did not provide an EIN.

Upgrade to Standard?

Standard Brands have fewer restrictions.

Sole Prop vs. Standard

Understanding the difference prevents rejection loops.

What reviewers check for code 30903

Code 30903 is reported as "Sole Proprietor Mismatch". The Sole Proprietor brand type is for individuals without an EIN. It allows one campaign and one phone number, requires one-time passcode verification on the owner's mobile, and cannot be used by companies that have an EIN, by resellers, or for restricted use cases. Reviewers reject registrations that do not meet these criteria or that do not match the owner's details.

Where code 30903 comes from

Code 30903 is one of the brand and campaign registration errors Twilio returns in its 30xxx error range when vetting fails. Other CSPs report the same underlying problem under their own reason codes, so the remediation below applies on any platform. It is marked High severity: it blocks approval, but it is fully fixable by correcting the submission and resubmitting.

Fix and verify before resubmitting

1. If the business has an EIN, register as a standard brand instead of a sole proprietor.
2. Use the owner's legal first and last name and a mobile number that can receive the verification OTP.
3. Complete OTP verification promptly; unverified sole proprietor brands expire.
4. Keep the campaign to a single permitted use case and a single number.
5. Confirm your CSP supports sole proprietor registration for your account type.
6. Resubmit with a note that references code 30903 (Sole Proprietor Mismatch) and lists each change made.

Sample resubmission note

Many CSPs let you add a note for the reviewer when you resubmit. A short, specific note shows what changed and speeds up the second review. Example for Ridgeway Auto Care:

Ridgeway Auto Care corrected the deficiency reported as code 30903 (Sole Proprietor Mismatch). Changes made: if the business has an EIN, register as a standard brand instead of a sole proprietor; use the owner's legal first and last name and a mobile number that can receive the verification OTP; complete OTP verification promptly; unverified sole proprietor brands expire. All URLs, keywords and auto-replies were re-tested from an external network before this resubmission, and the campaign text now matches the live opt-in exactly.

Common mistakes that keep code 30903 coming back

• Choosing sole proprietor to avoid EIN verification when an EIN exists.
• Using an office landline for OTP verification.
• Registering multiple sole proprietor brands for the same person.

Frequently asked questions about code 30903

Our CSP says sole proprietor is not supported. What now?

Some CSPs and account types (including ISVs registering for clients) do not offer sole proprietor registration. Obtain an EIN and register a standard brand, or move to a CSP that supports it.

Can a sole proprietor send marketing messages?

Yes, within the single campaign, if the opt-in, disclosures and content meet the same rules as any other campaign.

Legal Disclaimer: Code 30903 is an identity verification error. It ensures that individuals registering without an EIN are real people with verifiable addresses.
