What is a business registration number and why is it being required?
A Business Registration Number (BRN) is an official identifier issued by a government authority when a business is legally registered. It helps confirm that a business is legitimate and operating in line with local regulations.
Depending on where your business is registered, your BRN may be called something different. Common examples include:
ABN (Australian Business Number) — Australia
EIN (Employer Identification Number) — United States
Company Number / CRN — United Kingdom
NZBN (New Zealand Business Number) — New Zealand
For Toll-Free Verification (TFV), providing a BRN helps carriers and regulators verify the identity of the business sending messages. This builds trust, reduces spam and fraud, and helps ensure your messages are delivered reliably.
By verifying businesses at the source, BRNs help ensure messages:
Originate from a registered business entity
Align with known industry use cases
Meet opt-in and content policy expectations
Ultimately, this leads to stronger deliverability, reduced spam, and long-term trust for both businesses and their customers across carrier networks.
What are the current BRN requirements?
This section outlines the current Business Registration Number (BRN) requirements based on where your business is registered. Use the guidance below to make sure you provide the correct details for your region and avoid delays when submitting your Toll-Free Verification.
