What is Business Registration Number for Toll-Free Sender Verification?

[Sabaah_A]

To keep messaging safe, trusted, and reliable for everyone, Toll-Free A2P messaging industry is making updates to the Toll-Free Verification (TFV) process. Starting on September 30th, 2025, customers can begin including their Business Registration Number (BRN) as part of the submission process. 

*Beginning January 2026, BRNs will be REQUIRED for all new TFN verification submissions.

Business Registration Number: A unique identifier assigned to a business by a government authority or regulatory agency to identify and legitimize the business is recognized and allow to operate within a specific jurisdiction. For example, in the U.S., most businesses are required to have an Employer Identification Number (EIN), which is a 9-digit number issued by the Internal Revenue Service (IRS) used for tax filing, business reporting, and other uses.

US-Based Organizations

• Required BRN: Employer Identification Number (EIN)
• The EIN must match the legal business name in your submission.
• If no EIN is available (e.g., a self-run business or sole prop with no employees), additional vetting will be required upon review. Approval is not necessarily guarantee if a business is classified as sole-proprietor.
  
  

Organizations Outside the US

• Provide your official business registration number as issued by a national or local business authority.
• You must also include:
  • Legal business name
  • Issuing country
  • Name of the registration authority (e.g., Companies House in the UK, Canada Revenue Agency (CRA), Australian Business Register etc.)

Do I need to submit a new Toll-Free Verified Sender Form based on the new BRN requirements if my TFN is already verified?

• There is no need to re-submit a new form if your TFN has completed verification in the past with Sinch. Any new submissions going forward must follow the new requirements mentioned on Sinch’s online Toll-Free Verified Sender Form.

What is the benefit and purpose of providing a BRN?

• BRNs help reduce spam, improve message deliverability and build long-term trust across carrier networks by verifying that a brand is government-authorized, aligned with its campaign details, and comply with opt-in requirements and content policies.

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.
