Yes, completing a Verified Sender Form provides a simple layer of verification for your Toll-Free messaging campaign and with this verification it provides better deliverability than if you didn’t have a form on file.
Keep in mind that TFNs that are unverified (or have not yet been submitted for verification) are subject to the highest amount of filtering applied to their traffic, and are subject to daily, weekly and monthly message volume restrictions. TFNs in an unverified state will automatically get shut off if any spam or unwanted traffic is detected.
To learn more about traffic restrictions for unverified TFNs, please refer to the article What are the traffic restrictions for Unverified and Pending Verification TFNs?
Unverified toll-free numbers (TFNs) and Pending Verification toll-free numbers (TFNs) are subject to industry-wide message blocking. Unverified toll-free numbers are TFNs that have not completed the toll-free sender verification process. Pending Verification toll-free numbers are TFNs where a verification request has been submitted, but the request is pending review and approval.
Note: In the past it was possible to send messages from an Unverified TFN or Pending Verification TFN. However, as a result of industry-wide changes, all toll-free numbers, regardless of the use case, must be Verified to originate traffic.
UNVERIFIED toll-free numbers (TFNs) are subject to industry-wide message blocking, effective November 8, 2023.
PENDING VERIFICATION toll-free numbers (TFNs) are subject to industry-wide message blocking, effective January 31, 2024.
All toll-free numbers (TFNs) must be in a VERIFIED state in order to originate traffic.
Unverified TFNs and TFNs pending verification will be blocked with Sinch error code 64 “Blocked due to exceeded quota”. Please see Toll-Free Delivery Report Errors for a full list of Sinch Toll-Free error codes.
