How is the BN validated?
The Business Number (BN) is a unique 9-digit registration number assigned by the Canada Revenue Agency (CRA) to identify businesses to federal, provincial, and municipal governments.
This tool generates and validates structurally correct 9-digit BNs with optional 6-character program account suffixes (e.g., RC0001) for integration testing.
