Last updated: March 3, 2026
What is A2P 10DLC?
A2P 10DLC (Application-to-Person 10-Digit Long Code) is the industry standard for sending business text messages from standard 10-digit phone numbers. Since 2023, all major U.S. carriers (AT&T, T-Mobile, Verizon) require businesses to register their brand and messaging campaigns before sending SMS.
Unregistered messages are being blocked or filtered by carriers. If your SMS messages aren't being delivered, A2P 10DLC registration is likely the reason.
Why It Matters for Your Business
Message Delivery
Unregistered messages are increasingly filtered or blocked by carriers. Registration ensures your messages reach your leads.
Higher Throughput
Registered campaigns get higher message throughput (messages per second), so you can reach more leads faster.
Legal Compliance
Carriers can levy fines for non-compliant messaging. Registration protects your business from penalties.
Brand Trust
Registered messages are less likely to be flagged as spam, improving your brand reputation with carriers.
How LeedAgent Helps

Registration Process
- Connect Your Phone Provider: Bring your own Twilio account (BYOT). Connect your Twilio credentials in LeedAgent settings to enable SMS and voice.
- Register Your Brand: Submit your business information (legal name, EIN, address, website) for brand verification with The Campaign Registry (TCR).
- AI Underwriter Review: Our AI reviews your registration details and suggests improvements to maximize your trust score before submission.
- Create Messaging Campaign: Define your use case (e.g., appointment reminders, lead follow-up), provide sample messages, and submit for carrier approval.
- Start Messaging: Once approved, your messages are delivered with full carrier trust. Monitor delivery rates and compliance from your dashboard.
Costs & Fees
A2P 10DLC registration involves one-time and recurring fees charged by carriers and The Campaign Registry. These are industry-standard fees, not LeedAgent charges:
| Fee | Amount | Frequency |
|---|---|---|
| Brand Registration | $4 | One-time |
| Campaign Registration (Standard) | $15 | One-time per campaign |
| Campaign Monthly Fee | $10/mo | Monthly per campaign |
| Brand Vetting (optional) | $40 | One-time (higher trust score) |
Fees are subject to change by carriers and TCR. Per-message carrier surcharges also apply. LeedAgent does not add markup to these registration fees.
