Improving Your Chances of Toll-Free Verification Approval

What is Toll-Free Verification (TFV)?

This post is relevant for you if you already have a Toll-Free Phone Number (TFN) in your account and want to start using it. 

To be able to send messages from your TFN, you will first have to verify it. As of January 31, 2024, messages sent from any unverified (Restricted or Pending) TFN are blocked in the US and Canada. Only fully verified TFNs are eligible to send messages. This is an industry standard and carrier requirement. 

For TFV we collect 3 types of information: your business details, your business use case and opt-in requirements (i.e. how customer consent to receive messages from your business is collected).

Best Practices for a TFV application

TFV applications often get rejected due to common errors. We discuss these errors and best practices so your TFV process is smooth!

1. Ensure Business Information is Accurate and Verifiable

Rejections occur when we receive business details that are incomplete, incorrect, or unverifiable. To avoid this:

  • Ensure your business name, website, and email domain match and are publicly accessible.
  • Use an official business email rather than a freemail account (e.g., use yourcompany.com instead of gmail.com).
  • Make sure the submitted business details align with your legal business name. Some companies may have a legal entity name such as “Company Name LLC” as well as a different public name known by the customers. The latter is referred to as the Doing Business As or DBA. If this applies to your case, please include both names in the request (you will see fields for both names in the form). 

Tips for Independent Software Vendors / end businesses using ISVs

  • An ISV setting up Toll-Free services on behalf of their client must include the end business information, client’s name, contact email, address, and website. Twilio has streamlined TFV for ISVs and their clients through Compliance Embeddable. This will ensure your clients can go to market much faster.
  • If the TFN is being requested directly by the End Business but this company is using an ISV to gather consent for text messages or even powering their whole SMS services, then please include the name of this ISV in the “ISV/Reseller” field

2. Ensure that your company’s online presence can be validated

Another common rejection reason is because we are unable to validate the business URL provided in the application. This happens when:

  • The website has no content or is under development.
  • The site is private, password-protected, or otherwise inaccessible.
  • The URL is misspelled or does not match the business name.

If your company’s website is publicly unavailable or under construction, you can share publicly available social media pages (e.g., LinkedIn) for your business.

3. Specify Your Use Case Clearly

Clearly defining your use case is critical for TFV approval. The more detailed information you provide for the use case/ summary the better. Most commonly, TFV requests are rejected because the use case description is vague or incomplete. 

  • A good example of use case  is “This number will be used to send out promotional offers and coupons to the customers of [Company Name]”. Or “This number will be used to send out order confirmation and delivery information to the customers or [Company Name]”
  • A bad example is “Marketing” or “Status”

Please note that some use cases such as communications related to multi-level marketing, illegal substances, debt collection, etc. are prohibited by carriers and will be automatically rejected.

4. Provide Opt-In Consent with Clear Documentation 

[Note: each type of opt-in will be a collapsible tab so customers don’t have to go through every type of opt-in]

Opt-in consent is required for TFV to ensure recipients have explicitly agreed to receive messages from your business. 

General considerations for all forms of opt-in 

  • Opt-in should not be embedded with other agreements (e.g., embedded deep in your Terms of Service or Privacy Policy). 
  • Consent cannot be shared across multiple use cases (e.g., receiving order confirmation and receiving coupons as marketing offers are two separate use cases requiring 2 different opt-in consents). You cannot mix and match or use 1 opt-in consent for both. But you can group consent within a single use case (e.g. coupon alerts and new product launches would be considered as two marketing use cases that can be bundled together.)
  • Opt-in must be branded, which means that the name of the end business must be mentioned in it. This could be written or through a display of the company logo. 
  • Opt-in cannot be shared across businesses or sold to third parties. 

You can meet the Opt-in requirements for your TFN through verbal, web/online, paper, mobile QR code, and text-based consent. To see more details, please click on the method that your company will use to obtain customer consent for your use case. 

  1. Web/Online Opt-in must be a standalone consent form present on your website / app (e.g., please check this box to opt-in for promotional messages from [Company Name]). 
  2. Verbal Opt-in requires a detailed script showing how consent was collected. 
  3. Paper Opt-in should be a signed document clearly indicating consent for messaging (e.g. Please sign here to opt-in to receive promotional messages from [Company Name])
  4. Mobile QR opt-in should lead to a web form to opt-in with a phone number OR to a templated message in the user’s messaging app seeking opt-in consent
  5. Text-based opt-in consent should provide keyword campaign information (e.g. Text ‘Subscribe’ to 12345 to receive updates)

1. Web/Online opt-in

Some things to consider when using a web/online opt-in:

  • Provide URLs or images of the opt-in request from your website/ application. You can take a screenshot of the webpage showing how you ask for user consent.
  • Online opt-in can be a form on your company’s website that prompts end-users to enter their mobile handset phone number and opt into the texting campaign (as shown in the example below). 
  • Checkbox should not be preselected and should be selectable by the end-user if they decide to opt in.

Example of web/online opt-in (Build your own web Opt-In template here)

Contact form requesting first and last name, email, phone, marketing consent, and terms agreement.

2. Verbal opt-in

Some things to keep in mind when using a verbal opt-in:

  • If you choose VERBAL, you must provide the sample verbal consent collection. Please copy paste the script in the OptInImageURLs document.
  • Verbal consents are not sufficient for Marketing use cases. For Marketing use-cases, “written” consent is required. Requiring a customer to select a checkbox on a website or providing signatures or opting in via text is adequate. 

Example of Verbal opt-in 

Twilio IVR: "As part of our service we can send you automated monthly text alerts regarding Twilio account payment activity. We will send two messages per month. Message and data rates may apply, depending on your mobile phone service plan. At any time you can get more help by replying HELP to these texts, or you can opt out completely by replying STOP. 

Twilio Customer: "Yes please"

Twilio IVR: "Great! We will send you a text message to confirm your enrollment here shortly."

3. Paper opt-in

Some things to consider when using paper opt-in:

  • If you choose PAPER_FORM, you must provide the form in the OptInImageURLs document

Example

An in-store visitor completes a physical form that collects their phone number and their consent to subscribe to your texting campaign

4. Mobile QR opt-in

Some things to consider when using paper opt-in: 

  • If you choose MOBILE_QR_CODE, you must provide the QR Code in the OptInImageURLs document.
  • Please include a brief explanation of how the end users will get to know where the QR is located. This could be, for example, mentioning that the end users will find the QR in a banner placed in the cashier when paying for a product, in a social media advertisement, etc. This information has to be included in the "Opt in Workflow Description" field in the TFN request

Example of Mobile QR opt-in

Contact form requesting first and last name, email, phone, marketing consent, and terms agreement.

5. Text-based opt-in

Some things to consider when using text-based opt-in:

  • If you choose VIA_TEXT, you must provide the keyword campaign information (e.g. text ‘Subscribe’ as stated in the above example) in the OptInImageURLs document
  • Please include a brief explanation of how the end users will get to know where the keyword is located. This could be, for example, mentioning that the end users will find the keyword in a banner placed in the cashier when paying for a product, in a social media advertisement, etc. This information must be included in the "Opt in Workflow Description" field in the TFN request.

Example of text-based opt-in

Text alerts subscription flyer with a keyword, QR code, and information about receiving promotional SMS.
