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 and businessCountry). 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.  ... View more

Certain types of content are not allowed on toll-free numbers. Here is a list of what NOT to send via text from your business’s toll-free number:   High-risk financial services: Promotion of high-risk financial services is not allowed on toll-free numbers. This includes payday loans, short-term-high interest loans, auto loans, mortgage loans, student loans, third-party lending programs, gambling, sweepstakes, stock alerts, and cryptocurrency. All 1st party and 3rd party loan marketing are blocked and disallowed. However, if your content is account-related or is not promoting disallowed content (like a casino promoting a dinner show or an OTP for account login), it may be okay. “Get rich quick” schemes: This includes content related to or promoting work from home programs, risk investment opportunities, and multi-level marketing. Third-party debt collection: This includes third-party debt collection and consolidation. Examples include debt reduction, debt forgiveness, and credit repair programs. Controlled substances: This includes federally illegal drugs, such as medical marijuana and cannabis dispensaries (even if legal in your state). SHAFT content: SHAFT stands for Sex, Hate, Alcohol, Firearms, and Tobacco. Examples include pornographic or sexually explicit content, profanity or hate speech, products containing alcohol, content related to guns or other weapons, and tobacco products (including vape, cigars, and smoke/vape shops). * Indirect marketing: Only direct marketing content is allowed on toll-free numbers. Promotions must come directly from the brand, not sent by a third party. Lead generation (selling or sharing customer opt-in data with third parties) is also not allowed. All of the above categories are considered disallowed content on toll-free numbers.    *Alcohol-related content is allowed to be sent from toll-free numbers to US destinations with an age gate. An acceptable age gate would consist of, at minimum, a recipient entering a day, month, and year confirming their age at messaging opt-in prior to receiving messaging. A tick box, check box, or age gate that asks if the recipient is over a certain age is not considered an acceptable age gate. At this time any content that requires age gating is not allowed to be sent from toll-free numbers to Canadian destinations. ...

A compliant opt-in process (also called a "Call to Action") is required to get your toll-free number (TFN) verified. A compliant opt-in process means the way you get people’s consent to send them messages. You can only use a business messaging service to send messages to people who've given their explicit consent to receive those messages from you. This applies to all business messaging, including sending to employees.     If you don’t provide evidence of a compliant opt-in process, your TFN cannot be verified and you won’t be able to keep sending messages. If you don’t currently have a compliant opt-in process, you’ll need to create one to in order to get your TFN verified.   Opt-in language in Terms & Conditions or Privacy Policy is NOT considered compliant opt-in. TFNs used for Marketing/Promotional use cases MUST include visual documentation (i.e. screenshot, live URL) of a compliant opt-in process in order to get verified.   Examples of accepted methods of opt-in documentation include: Website opt-in: Screenshot or URL of webform where the client adds number and agrees to receive messaging. Website Posting: Screenshot or URL of where the number is advertised or where the customer finds the number to text in. Keyword or QR Code Opt-in: Screenshot or copy of material showing where customer finds the keyword in order to opt-in to receive messages. If a QR code is provided, please include the URL that the QR code redirects to (ex. opt-in webform or webpage) where the end user provides their phone number with SMS disclosures.  There’s a legal requirement for businesses to obtain written consent before sending customers promotional text messages when using a keyword as a business must do a double Opt-in process. The customer provides their phone number on a form on a business’ website in exchange for a discount on their first purchase (first opt-in). The business sends them a text message that includes the instruction “Reply YES to receive promotional messages.” The customer replies “YES” (second opt-in). The business now has explicit written consent to send the customer promotional messages. Voice/IVR opt-in: Verbal script and detailed description of process to opt-in. 2FA/OTP: Screenshot of process to receive the initial text. Paper form: Screenshot or copy of form. ... View more

If you are migrating a verified TFN to Sinch, the verification status will not change, but verification submission data is not migrated.
