Why Was My A2P 10DLC Campaign Rejected?
If your A2P 10DLC campaign registration was rejected, you must correct the identified issue before submitting a new registration request.
Most A2P 10DLC campaign rejections occur because of incomplete business information, unclear opt-in processes, missing compliance documents, or sample messages that do not match the registered use case.
This guide explains the most common rejection reasons and how to resolve them.
Invalid Campaign Description
Your campaign description should clearly explain:
- What your business does
- Who receives your messages
- Why messages are sent
- The type of messages being delivered
Avoid vague descriptions such as:
“Customer notifications”
Instead, use a detailed description such as:
“We send appointment reminders and follow-up notifications to customers who opt in through our website.”
Additionally, if you are registering on behalf of customers as an ISV or software provider, mention that in the campaign description.
Sample Messages Do Not Match the Use Case
Sample messages must accurately reflect the messages you plan to send.
For example, if you register a marketing campaign but provide authentication code examples, carriers may reject the campaign.
Furthermore, at least one sample message should include your business or brand name.
Sample messages should:
- Match the selected campaign use case
- Reflect actual customer communications
- Include template placeholders when applicable
- Clearly identify your brand
Website Issues
The website submitted during registration must:
- Be publicly accessible
- Match your business name
- Clearly describe your products or services
However, registrations are commonly rejected when:
- The website is unavailable
- The website is under construction
- The website does not match the registered business
- The website lacks business information
If your website has not launched yet, clearly mention that in your campaign description.
Missing Opt-In Information
Carriers require proof that recipients consent to receive messages.
Because of this, you should clearly explain:
- How users provide consent
- Where consent is collected
- What messages users will receive
- How frequently messages are sent
Common opt-in methods include:
- Website forms
- Contact forms
- Appointment booking forms
- Customer signup pages
- Paper consent forms
If consent is collected through a website, ensure the website clearly displays SMS consent language.
Missing Opt-Out Process
Recipients must have a simple way to stop receiving messages.
For example, many businesses support keywords such as:
- STOP
- UNSUBSCRIBE
- CANCEL
Additionally, your registration should explain:
- Supported opt-out keywords
- Confirmation messages sent after opt-out
- How future messages are prevented
We recommend including language such as:
“Reply STOP to unsubscribe.”
Missing Privacy Policy or Terms of Service
Many A2P 10DLC campaign rejections occur because required compliance documents cannot be verified.
Your website should provide:
- A publicly accessible Privacy Policy
- A publicly accessible Terms of Service page
In addition, include direct links to these pages when completing your registration.
Common Compliance Mistakes
Before submitting your campaign, review the following:
- Using public URL shorteners in sample messages
- Submitting incomplete websites
- Providing inaccurate business information
- Registering one use case while describing another
- Missing opt-in disclosures
- Missing opt-out instructions
- Sharing SMS consent with third parties
As a result, even small inconsistencies can delay approval.
Prohibited Messaging Categories
Some campaign types cannot be approved regardless of registration quality.
Examples include:
- Illegal substances
- Gambling
- Phishing
- Fraudulent marketing
- Debt relief schemes
- Unauthorized lead generation
- High-risk financial promotions
If your use case falls into a prohibited category, carriers may permanently reject the registration.
Before You Resubmit
Before creating a new A2P 10DLC campaign registration request, verify the following:

✓ Privacy Policy is available
✓ Terms of Service is available
