Toll-Free Numbers Verification API

Overview

A toll-free number can be used to send messages in US & Canada once it passes an additional verification process. Users who don’t verify their toll-free numbers will be blocked from sending messages as of November 8, 2023.

A verified toll-free number ensures that the business owning the number is identified, and that the message's content has been reviewed and does not oppose the Disallowed Content Policy. This process ensures better deliverability and less filtration.

To set up a new channel to send SMS messages using a toll-free number the following steps are required.

API Access

The following API requests can only be made using a valid access key, and attached to an access role, with an access policy that at least specifies the permissions to the resources outlined in each section below. Learn more about API access.

If you do not already have a US or Canadian toll-free number available in your workspace you can find one to purchase.

Submit a verification application for a toll-free number(s)

To reduce the likelihood of rejection, ensure you are familiar with TFN registration examples and best practices. Specifically

• Check this article for tips on how to write an effective useCaseSummary

• Check this article on how to write an effective optInWorkflowDescription

Most TFN rejections are caused by unclear or incomplete useCaseSummary and/or optInWorkflowDescription

A-Sync : this will start a background process that may require some time to complete. A Get call may be required to to retrieve the final result .

Before you can use a toll-free number to send SMS messages, you must submit a toll-free number verification request and wait for it to be approved.

You can submit one toll-free number per verification request.

You are not allowed to submit the same number twice, unless the previous submission was resolved with status Rejected or Verified.
