Registering your A2P 10DLC campaign is an important step in enabling SMS messaging for your business. Carriers carefully review every registration to verify that businesses are collecting consent properly, sending compliant messages, and protecting consumers.

The good news is that most rejections can be avoided by providing clear, complete, and consistent information.

Before submitting your registration, use the checklist and guidance below to make sure you're ready.

5-Minute A2P Submission Readiness Checklist

Before submitting your campaign, confirm that all of the following are true:

☐ Your website is live and publicly accessible

☐ Your website clearly identifies your business and services

☐ Your Privacy Policy is published

☐ Your Terms & Conditions are published

☐ Your website includes SMS consent language where phone numbers are collected

☐ Your SMS consent checkbox is not pre-checked

☐ Your campaign description clearly explains your messaging use case

☐ Your message samples reflect actual messages you plan to send

☐ Your business name matches across your registration and website

☐ You have a screenshot of your opt-in form showing consent language

If any of these items are missing, we recommend fixing them before submitting your registration.

The 5 Most Common Reasons Campaigns Get Rejected

Most rejections fall into one of the following categories:

1. Missing SMS Consent Language

Users must clearly agree to receive SMS messages before you can message them.

2. Generic Campaign Descriptions

Descriptions such as "We send SMS messages to customers" do not provide enough information for review.

3. Missing Privacy Policy Disclosures

Your Privacy Policy should explain how phone numbers are collected and used.

4. Insufficient Proof of Opt-In

Carriers must be able to verify how users consent to receive messages.

5. Inconsistent Business Information

Your business name, website, campaign description, and message samples should all align.

Step 1: Write a Clear Campaign Description

One of the most common rejection reasons is a campaign description that is too vague.

Your campaign description should explain:

What your business does
What types of messages you send
Who receives those messages
How users opt in
That message frequency may vary
That message and data rates may apply
That users can reply STOP to opt out
That users can reply HELP for assistance

Bad Example

"We send SMS messages to customers."

Good Example

"[Business Name] uses this SMS campaign to send conversational customer care messages and promotional content to users who opt in through our website, landing pages, or online forms. Messages may include appointment reminders, account updates, order confirmations, customer support responses, and occasional marketing offers or service announcements. Message frequency varies. Message and data rates may apply. Users can reply STOP to opt out or HELP for assistance."

The more specific and transparent your description is, the smoother the review process will be.

Step 2: Clearly Explain How Users Opt In

Carriers require proof that users have explicitly agreed to receive SMS messages.

Your consent language should:

Identify your business
State that the user is agreeing to receive SMS messages
Explain the types of messages they will receive
Include message frequency disclosure
Include message and data rate disclosure
Explain STOP and HELP commands

Pre-checked boxes are not allowed.

Users must take a clear action to provide consent.

Bad Example

"Check here to receive updates."

Good Example

"By checking this box, you agree to receive transactional and informational SMS communications from [Business Name], including account notifications, customer care updates, appointment reminders, and service-related messages. Message frequency may vary. Message and data rates may apply. Reply HELP for help or STOP to opt out."

Marketing Consent Example

"By checking this box, you agree to receive promotional and marketing SMS communications from [Business Name], including special offers, promotions, and marketing updates. Message frequency may vary. Message and data rates may apply. Reply HELP for help or STOP to opt out."

If you send both marketing and informational messages, we strongly recommend using separate consent checkboxes for each type.

Step 3: Make Sure Your Website Is Ready

Carriers often review your website during the approval process.

Before submitting, verify that your website includes:

A visible Privacy Policy
Terms & Conditions
SMS consent language (if collecting phone numbers)
Accurate business information

Your Privacy Policy should clearly state:

That you collect phone numbers
How SMS information is used
That mobile information is not sold or shared for third-party marketing purposes

Use a Professional Business Domain

Whenever possible, use a website domain that belongs to your business.

Preferred

www.yourbusinessname.com

Avoid

yourbusiness.freewebsite.com

Your website should match the domain and business information submitted with your campaign registration.

Include a Screenshot of Your Opt-In Form

We strongly recommend providing a screenshot that clearly shows:

The webpage URL
Phone number field
SMS consent checkbox
Consent language presented to users

Providing this information upfront can help reduce review delays.

Step 4: Match Your Campaign Type to Your Messaging

The campaign use case selected during registration should match the messages you intend to send.

Marketing Campaign

Should primarily contain promotional content.

Customer Care Campaign

Should primarily contain support, account, or service-related messaging.

Mixed-Use Campaign

Should accurately disclose both conversational and promotional messaging.

Selecting the wrong use case can delay approval.

Step 5: Provide Realistic Message Samples

Message examples should reflect the actual messages you plan to send.

Every sample should:

Include your business name
Reflect a real use case
Include opt-out instructions
Include help instructions when appropriate

Bad Example

"Your request was received."

Good Example

"[Business Name]: Your request has been received. We'll notify you once it has been processed. Msg & data rates may apply. Reply STOP to opt out or HELP for help."

Avoid incomplete examples or placeholder content.

Step 6: Avoid Prohibited Content

Carriers prohibit certain categories of content, including:

Sexually explicit content
Hate-related content
Tobacco-related content
Firearms-related content
Illegal products or services
Deceptive or misleading messaging
Lead generation campaigns without direct brand interaction

Additional review may apply for regulated industries.

Final Pre-Submission Audit

Before submitting your registration:

Visit your website as a new visitor.
Locate the form where phone numbers are collected.
Confirm SMS consent language is visible.
Verify the consent checkbox is not pre-selected.
Review your Privacy Policy.
Review your Terms & Conditions.
Verify your business name matches your registration.
Confirm your message samples match your intended use case.
Capture screenshots of your opt-in process.
Submit your registration.

Taking a few minutes to complete this review can help prevent delays and improve your chances of approval.

What Happens After Submission?

Once your registration is submitted:

Your campaign enters carrier review.
Additional information may be requested if clarification is needed.
The carrier will either approve or reject the registration.
If approved, your campaign can begin using A2P 10DLC messaging.
If rejected, you'll receive feedback so corrections can be made and resubmitted.

Approval timelines vary depending on carrier review volume and campaign complexity.
