Business Number (BN) 

Canada Revenue Agency (CRA), Government of Canada

Your Business Number is a nine-digit account number that identifies your business to federal and provincial governments. You can open several different accounts for your business through a single registration. The accounts include:

  • GST/HST
  • Payroll deductions
  • Corporate income tax
  • Import/export
  • Other federal and provincial accounts

Businesses located in Quebec must register for the GST/HST with Revenu Québec. There may be additional business registration requirements in your province or territory.
