<Info>
  **Last updated:** July 22, 2025
</Info>

## Overview

If you're planning to send business SMS messages in the US or Canada, you must complete A2P (Application-to-Person) 10DLC registration with Twilio. This guide walks you through filing a compliant campaign registration to avoid rejections and ensure your messaging gets approved.

<Warning>
  **Required for US & Canada**: A2P 10DLC registration is mandatory before sending any application-generated messages to US or Canadian phone numbers. Start this process early as approval can take several weeks.
</Warning>

## What You Need Before Starting

Before beginning your A2P registration, ensure you have:

* A registered business with Twilio
* A clear opt-in process for collecting SMS consent
* Compliant message samples
* Privacy policy and terms of service
* Screenshots of your consent forms

***

## Step 1: Set Up Compliant Opt-In Forms

Your lead form must meet Twilio's strict requirements to ensure compliance.

### Required Elements

**1. Clear Opt-In Language**

Use explicit language that explains what users are agreeing to receive:

```
"Do you agree to receive SMS notifications about appointments and offers?"
☐ Yes, I agree to receive SMS messages from [Company Name]
```

**2. Separate Consent Checkbox**

<Warning>
  **Critical**: Do NOT bundle SMS consent with Terms & Conditions or Privacy Policy. SMS consent must be a separate, unchecked checkbox.
</Warning>

**3. Visible Policy Links**

Include direct links to your Privacy Policy and Terms of Service on the form. Your Privacy Policy must explicitly state:

> "Mobile information will not be shared with third parties/affiliates for marketing/promotional purposes."

### Form Checklist

* Separate SMS consent checkbox (unchecked by default)
* Clear description of what messages users will receive
* Privacy Policy link visible on form
* Terms of Service link visible on form
* Privacy Policy includes third-party sharing language

***

## Step 2: Describe Your Opt-In Process

In the **"How do end-users consent to receive messages?"** section of your Twilio application, provide a clear description of your opt-in process.

### Example Description

```
Users opt in via our website [yourdomain.com] and provide explicit consent 
to receive SMS communications from our company through a separate, 
unchecked checkbox on our lead form.
```

</CardGroup>

### Supporting Form Evidence for Your Application

When submitting your A2P campaign, you'll need to provide evidence of your compliant opt-in process in this field of your Twilio application.
This should be a link in the **"How do end-users consent to receive messages?"** field.

#### Documentation to Include

* **Either** screenshots of your complete opt-in form **OR** a direct link to the live form

<Note>
  **File Sharing**: Use a public file-sharing service like Google Drive, OneDrive, or Dropbox to host your documentation folder, then provide the link in your Twilio application.
</Note>

## Step 3: Create Message Samples

You'll need to provide two sample messages that represent the type of content you'll send.
