How do I submit my TFNs for verification in bulk?

[Meredith_W]

Verification requests for multiple senders (i.e. businesses) can be submitted in bulk via CSV file. This approach is useful if you have many Toll-Free Numbers to submit for verification for multiple senders. Please follow the instructions below to submit a bulk TFN verification request to Sinch.

Please note opt-in image is required and the bulk submission must include either a URL for an opt-in image mock up, or a live opt-in URL. If you needs assistance with hosting opt-in images online, please let your Sinch Account Manager know.

• Fill in the CSV template (found below) with the end customer’s verification information (For more information on the business contact info to provide, see this article.)
• Do not modify the column headers and save the file only as a .csv file.
• Each row should be unique to an individual business.
• If request is for new TFNs, leave “Phone_Number” column blank. Sinch will assign TFNs upon submission.
• Multiple numbers associated with a business can be included in the ‘Phone_Numbers’ column, separated by a semicolon. Make sure to include the reason why multiple numbers are required in the "Use_Case_Summary" column.
• There is a 1,000 character limit for the “Message_Content” and “Additional_Opt_In_Information” columns, and a 500 character limit for all other columns.
• If you would like to include a comma within a field value, surround the value with double quotes.
• Each column is required to have data within it (Excludes: BusinessAddr2, State, Zip, AdditionalDocumentation, ISV/Reseller, InternalTicket, businessCountry and External_Customer_Id).
• An opt-in image or live URL is required in “Additional_Opt_In_Information” column. This column must include either a URL to a hosted opt-in image mock up, or a live opt-in URL. If you needs assistance with hosting opt-in images online, please let your Sinch Account Manager know so that Sinch can assist with hosting.

Provide the completed CSV file to your Sinch Account Manager. Your account manager will let you know once your TFNs have been successfully verified, or if any further details are needed to process your submission.

Please use the Sinch Bulk TFN Verification template attached here for your bulk submission. You can also find a Sample Bulk TFN Verification template attached, for your reference.

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.
