This release is a **mandatory update** from The Campaign Registry (TCR) and is designed to enhance security, prevent brand impersonation, and ensure compliance with 10DLC messaging regulations. As of **October 3, 2024**, all new and existing brands marked with a PUBLIC\_PROFIT entity type must undergo this mandatory verification process. The process includes submitting a business contact email and completing Two-Factor Authentication (2FA) to validate the brand identity. Brands that fail to complete the verification process **will not** be able to register new campaigns or perform certain vetting actions. ### Key Features and Changes 1. **New Brand Verification Flow:** * For **new brands**, upon creation via the 10DLC API, a verification email will automatically be triggered to the business contact email provided. * New brands that do not complete the verification will remain in an **unverified state** and will be unable to register campaigns until verification is completed. 1. **Existing Brand Impact:** * **Existing brands** in a verified state can continue operating as usual, but they will be restricted from: * Adding new campaigns * Importing vetting * Requesting vetting * To restore full functionality, existing brands must **update their business contact email** and complete the 2FA process to re-verify their status. 1. **Two-Factor Authentication (2FA):** * Telnyx will send a verification email with a unique link and PIN to the business contact email. * The verification email is valid for **7 days**. If not clicked, the brand remains unverified. * If the verification process is not completed within **30 days**, the brand will remain unverified and need to be resubmitted via the API. 1. **API Endpoint Updates**: * New field: businessContactEmail is now required for PUBLIC\_PROFIT brands when creating or updating a brand. * Upon updating this email, a new 2FA verification process will be triggered. ### API Integration To update the business contact email or trigger a resend of the verification email, the following API calls can be used: * Update Business Contact Email: curl -X PATCH \--header 'Authorization: Bearer YOUR\_TOKEN\_HERE' --header 'Content-Type: application/json' -d '{"businessContactEmail": "[\[email protected\]](https://telnyx.com/cdn-cgi/l/email-protection#4c3523393e6229212d25206224293e290c29342d213c2029622f2321)" }' * Resend 2FA Verification Email: curl -X POST \--header 'Authorization: Bearer YOUR\_TOKEN\_HERE' ### Portal Availability While the brand verification flow is currently available only via the API, it will be accessible through the Telnyx portal in an upcoming release. ### Action Required * **New Brands:** Ensure that your brand completes the verification process upon creation by following the 2FA link sent to the business contact email. * **Existing Brands:** Update your brand’s business contact email via the API to trigger the new verification flow and maintain full functionality for campaigns and vetting. ### Why This Update Matters This is a **mandatory update from TCR**, and we encourage you to take these steps to avoid disruptions to your campaigns by **October 3, 2024**. This will help with our ongoing efforts to enhance security, reduce the risk of fraud (e.g., brand impersonation, smishing), and ensure compliance with carrier regulations for 10DLC messaging. By implementing a robust 2FA verification system, we aim to ensure that only authorized personnel can manage and operate messaging campaigns.
