SMS Sender profile registration
Last updated on: July 18, 2023

Complete your Sender Profile registration to avoid blocked messages

Anyone sending SMS or MMS messages to U.S. or Canadian numbers must complete their Sender Profile Registration. This registration keeps you in compliance with the 2023 update to the Telephone Consumer Protection Act (TCPA).

If you send messages without registering, carriers such as AT&T, T-Mobile, Verizon, etc. will likely block your messages. You will still be charged for sending blocked messages.

To avoid this, submit your Sender Profile Registration here. And use the information below to successfully complete your registration. Reach out to our Support team with any questions!

Note that The Campaign Register (TCR) reviews each submission manually. Their review might take a few weeks, and they may contact you for more information.

This article will help you successfully submit your Sender Profile registration so you can send SMS/MMS messages to numbers in the US and Canada.

SMS Sender Profile registration

In March 2023, the Federal Communications Commission (FCC) enhanced the rules of Application-to-person (A2P 10DLC) messaging to combat spam and scams from text messages. A2P 10DLC messaging is a system that allows apps such as Twilio and Ontraport to send SMS and MMS messages quickly and reliably.

Any businesses sending SMS or MMS messages from an app (including Ontraport and our SMS provider, Twilio) to US or Canadian phone numbers must now be registered. This registry is designed to promote transparency about who is sending SMS messages and their purpose. To see the full report by the FCC released in March 2023, click here.

Registering your Sender Profile involves brand verification and campaign use case vetting.

  • Brand verification establishes your company with a governing body.
  • Campaign vetting confirms that the purpose and types of SMS messages you’re sending in a campaign align with your brand.

In this article, you’ll find information about the different registration types as well as guidance on how to successfully submit your Sender Profile registration.

Twilio Brand verification

Back to top

Brand verification contains information about your company. Every Ontraport customer sending SMS messages to contacts in the US or Canada (even if you do not reside in the US or Canada) must provide information about their company. This information is sent to The Campaign Registry, the reputation authority for customers sending SMS messages through an app.

  • There is a one time $10 brand registration fee associated with this process
    • Note: If your brand verification is not submitted successfully after three attempts, you will be charged an additional $10 fee to restart the process.
  • To avoid delays on your brand registration, ensure the information you submit is accurate. The application requirements differ based on whether you’re registering as a sole proprietor and whether you are a low or high volume customer.
    • See the diagram below to determine which registration type applies to your business.
  • Learn more about each registration type below, or visit the Sender Profile Registration page here to get started on your application.

  • You have a valid address in the US or Canada.
  • You have a valid US or Canadian mobile phone number.

Preventing brand registration failure

Some brand registrations fail and need to be amended and resubmitted. Here are the most common reasons brand registrations are rejected:

  • The business contact cell phone number is not a valid US or Canadian cell phone number.
  • The applicant did not reply to the SMS compliance message from The Campaign Registry within 24 hours.
  • The email address is not a valid domain or uses a freemail or disposable email address (Gmail, Yahoo, etc.)
  • The physical address is not a valid US or Canadian address.
  • The brand name is not the applicant’s real business name.

See Twilio here for more reasons brand registration can fail.

  • Select “other” if your business registration type is not included in the dropdown.

Your EIN, CCN, ACN or equivalent business registration number that matches the values on your tax registration document

  • This should not be a “doing business as” (DBA) name.

    • Alberta Corporation Number
    • British Columbia Corporation Number (the BC prefix is part of the number)

Twilio Campaign Use Case vetting

Back to top

The second part of the registration process is campaign use case vetting. Mobile carriers need to confirm that the purpose and types of SMS messages you’re sending align with your brand. This process gives mobile network operators (AT&T, T-Mobile/Sprint, Verizon, etc.) a way to control message traffic on their networks.

  • There is a one-time $40 campaign vetting fee associated with this process.
    • After approval, there is an ongoing campaign use fee of $5/month. The fee is $20/month for High Volume.
  • Read more about Twilio’s campaign approval best practices here.
    • Note, Twilio does not allow certain categories of message types on its platform, including messages about high-risk financial services, third-party lead generation services, debt forgiveness, illegal substances, prescription drugs, gambling, sex, hate, alcohol, firearms, and tobacco.

There are four parts of your Campaign Use Case that will be evaluated:

  1. Message Flow
  2. Campaign Description
  3. Sample SMS Messages
  4. Sender Compliance Message

Message Flow

Back to top of section

In this section, describe how and where a contact can opt in to receive SMS messages from you. It proves that contacts are legitimately consenting to receive messages from you.

  1. The call to action must be explicitly clear and inform the receiver of the types/nature of SMS messages they’ll receive from you.
  2. If there is more than one way a contact can opt in to receive SMS messages, such as a form on a website, paper form, form behind a membership login, or by sending a message to your SMS number, list them all here.
Opt-in methodMessage flow must include:Example message flow description

Website form on your website

  1. A link to your website
    • Your site will need terms of service and a privacy policy. Your privacy policy needs to include a statement of non-sharing for mobile numbers, message frequency, and a “message and data rates may apply” disclosure.
    • Your site must have an SSL certificate.
  2. A link to the page where you collect SMS numbers

“Customers opt-in by filling out a registration form on this page: and entering their SMS number into the non-required field.”

Texting a message to your number

  1. Opt-in keywords they need to include in their message
  2. Opt-in message they will receive

“Customers send us a text message to get information about our product. Our offer of information includes the following message: “By sending us a message, you authorize ACME to send text messages with offers and other information. Message/data rates apply. Consent is not a condition of purchase. Text STOP to unsubscribe at any time.” [Page//Link to terms and conditions]

Paper form or form behind a membership login

  1. A hosted link to an image of your opt-in form
  2. A “message and data rates may apply” disclosure

“Customers opt-in by filling out this form: [Page//hosted link with a screenshot of opt-in form].”

Campaign Description

Back to top of section

In this section, explain the campaign’s objective or purpose in detail. Your description should include the type of messages you’ll send. What you describe must be appropriate and realistic for your brand. For example, a software company should not describe a campaign for a food delivery messaging campaign use case. And if you specify that the campaign’s purpose is to send appointment reminders, you can not also send messages about other topics, such as new products and services.

Here are a few example campaign descriptions:

  • “This campaign allows customers to confirm when they’ve made changes to their own profile or preferences.”
  • “This campaign provides shipping alerts to customers about products they ordered on [Page//website name].”
  • “This campaign sends SMS webinar reminders to clients who have opted in.”

Sample SMS Messages

Back to top of section

In this section, provide sample messages that are typical of this particular campaign. These messages should also be consistent with your campaign description.

  • Ensure that at least one sample message includes your business name.
  • Ensure at least one sample message includes opt-out language.
  • Use brackets to indicate any merge fields you are using.

Here are some examples of effective and ineffective sample SMS messages.
