Registering your business for text messaging involves carrier-mandated setup and monthly fees established by major US telecom networks, not software markups. Total initial registration costs typically range between $15 and $60 in one-time setup fees, followed by a $1.50 to $10 monthly campaign maintenance fee passed through directly from telecommunication clearinghouses.
Why SMS Registration Fees Exist
In the past, businesses could text clients from standard phone numbers without formal approval. To combat spam and fraudulent messaging, US wireless carriers (AT&T, Verizon, and T-Mobile) established a framework called A2P 10DLC (Application-to-Person 10-Digit Long Code).
Under these industry regulations, managed by an independent organization called The Campaign Registry, any business sending automated texts—including review requests, appointment reminders, and customer follow-ups—must register their legal entity and text templates before messages can be delivered.
These registration procedures ensure compliance with federal consumer privacy laws like the FCC Telephone Consumer Protection Act (TCPA). The fees associated with registration cover the cost of verifying your legal business identity, inspecting your messaging use cases, and maintaining your verified status on mobile networks.
Core Fee Breakdown
When registering your phone number for business text messaging through SoTrustworthy, four distinct carrier fee categories apply:
1. Brand Registration Fee (One-Time)
Before sending texts, your business must register as a recognized "Brand." This process verifies your Employer Identification Number (EIN) or Tax ID against legal state and federal business registries.
- Standard Business Brand Registration: $44 (one-time)
- Sole Proprietorship Registration: $4 (one-time, for individuals without an EIN sending very low volume)
Most home-service businesses—such as plumbers, HVAC contractors, electricians, and cleaning services—register as a Standard Business Brand using their official company EIN.
2. Campaign Vetting Fee (One-Time)
Once your Brand is approved, you must register your specific "Campaign." A campaign defines why you are texting customers and what your messages say. For SoTrustworthy users, this campaign covers customer feedback and review requests.
- Campaign Submission & Vetting Fee: $15 (one-time per submission)
Third-party vetting agencies review your sample text templates, privacy policy link, and opt-in disclosure during this process to ensure your texts adhere to anti-spam guidelines.
3. Monthly Campaign Maintenance Fees (Recurring)
Telecom networks charge a monthly administrative fee to keep your registered campaign active on their routing gateways. This fee depends on your messaging volume:
- Low-Volume / Starter Campaigns: $1.50 to $2.00 / month (ideal for businesses sending under 6,000 texts monthly)
- Standard / High-Volume Campaigns: $10.00 / month (for higher volume or multi-use messaging)
For almost all local service providers using SoTrustworthy, a Low-Volume Campaign ($1.50–$2.00/month) provides more than enough capacity for daily automated review requests.
4. Carrier Pass-Through Surcharges (Per-Message Micro-Fees)
In addition to fixed registration fees, wireless carriers charge small fraction-of-a-cent surcharges on every outbound and inbound text message segment.
- AT&T: ~$0.003 to $0.005 per SMS segment
- Verizon: ~$0.003 to $0.005 per SMS segment
- T-Mobile: ~$0.005 per SMS segment

Unexpected Fees and How to Avoid Them
Failing an SMS registration audit can lead to unnecessary extra costs. Below are common mistakes that cause unexpected carrier charges and how to prevent them:
Resubmission Fees ($15 per attempt)
If your campaign application is rejected by vetting clearinghouses due to mismatched business details, you must pay a $15 resubmission fee to apply again.
- Prevention: Ensure the Legal Business Name and EIN listed in your registration match your official IRS paperwork (such as your CP575 form or W-9) word-for-word. Even minor discrepancies—like listing "LLC" on your application when your IRS form says "L.L.C."—will trigger an automatic rejection.
Non-Compliance Fines
Major carriers, particularly T-Mobile, enforce strict monetary penalties for businesses sending non-compliant, unregistered, or deceptive text messages over their networks. Penalties for severe violations (such as missing opt-out language, sending prohibited content, or impersonation) can range from $500 to $10,000 per violation.
- Prevention: Always send messages using SoTrustworthy’s pre-approved compliant templates. Never modify your system to remove required opt-out disclosures like "STOP to opt out."
Unregistered Message Penalties / Blocking
If you attempt to send commercial SMS review requests without completing A2P 10DLC registration, carriers will silently block your texts or charge elevated unregistered messaging fees (up to 10x standard carrier rates).
- Prevention: Complete your registration inside SoTrustworthy before activating automated SMS review triggers.
