What happens when a Toll-Free message is identified as spam?

[Meredith_W]

Messages identified as SPAM will be rejected and error code 255 returned. Sinch continuously monitors for senders with a high number of SPAM rejections. If the SPAM message content is not resolved, the TFN is subject to blocking and deprovisioning. 

Please see our developer docs for more information on error codes.

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.
