Understanding 10DLC Registration for SMS Messaging

Overview

If you plan to send SMS or MMS messages to customers in the United States using the bLoyal Engagement Solution, you are required to complete 10DLC registration before launching campaigns.

10DLC stands for 10-Digit Long Code. It is the industry-standard framework that allows businesses to send application-to-person (A2P) text messages using local 10-digit phone numbers.

This registration process helps mobile carriers:

• Verify your business identity
• Understand how you plan to use messaging
• Reduce spam and fraudulent traffic
• Improve message deliverability and throughput

Completing 10DLC registration ensures your messages are delivered reliably and in compliance with carrier regulations.

Why 10DLC Registration Is Required

U.S. mobile carriers require all businesses sending SMS messages over standard 10-digit numbers to register their:

1. Business information
2. Brand
3. Messaging use cases (campaign types)

Without proper registration:

• Messages may be blocked or filtered
• Delivery speeds may be restricted
• Messaging services may be suspended

To protect your brand and ensure high deliverability, 10DLC registration must be completed and approved before you begin sending customer-facing campaigns.

Who Needs to Register?

You must complete 10DLC registration if:

• You are sending marketing or promotional SMS messages
• You are sending loyalty or rewards notifications
• You are sending order updates or account alerts
• You are using SMS for customer engagement or support
• Your audience includes U.S. mobile numbers

If you are unsure whether your use case requires registration, your Client Success Manager can help determine this.

What 10DLC Registration Covers

The registration process connects three key elements:

1. Your Business (Brand Registration)

This verifies your legal business identity.

2. Your Messaging Campaign(s)

This defines:

• The type of messages you will send
• Who will receive them
• How customers opt in
• Sample message content

3. Your Sending Phone Numbers

Your registered campaigns are linked to the phone numbers used to send SMS messages.

Benefits of Completing 10DLC Registration

Once approved, you can expect:

• Higher message deliverability
• Faster sending speeds
• Reduced carrier filtering
• Compliance with U.S. carrier regulations
• Increased trust with mobile networks
