Common Reasons 10DLC Registrations Are Rejected (and How to Avoid Them)

Overview

Carrier review is strict. Even small inconsistencies can cause delays or rejection.

Below are the most common issues — and how to prevent them.

1. Incomplete or Vague Use Case Description

Problem:

“Sending promotional messages to customers.”

Why it fails:

Too broad and lacks detail.

Solution:

Clearly explain:

• Who signs up
• How they sign up
• What type of messages they receive
• Approximate frequency

2. Missing Brand Identification in Message Samples

Messages must clearly identify your business.

Incorrect:

“Get 20% off this weekend!”

Correct:

“ABC Retail: Get 20% off this weekend! Reply STOP to unsubscribe.”

3. No Opt-Out Language in Samples

All samples must include:

• “Reply STOP to unsubscribe”
• Or equivalent language

4. Weak or Non-Compliant Opt-In Process

Carriers may reject registrations if:

• Consent is implied but not explicit
• Checkboxes are pre-selected
• There is no record of consent

Ensure:

• Customers actively opt in
• Terms clearly disclose SMS messaging
• Opt-in language is visible and documented

5. Website Mismatch

If your website:

• Is under construction
• Does not match your business name
• Does not describe your services

Approval may be delayed.

Ensure your website clearly reflects your brand and business activity.

If Your Registration Is Rejected

Don’t worry — this is common.

Your Client Success Manager will:

• Explain the rejection reason
• Recommend changes
• Resubmit your registration

Most rejections are resolved quickly with minor adjustments.
