A Business Number (BN) is a unique identifier the Canada Revenue Agency (CRA) assigns to track a business’s dealings with the government. This number becomes particularly crucial as it simplifies the management of federal tax and program accounts for businesses across Canada. When a business incorporates, it is automatically assigned a BN, which is integral to its operations, including tax filings and setting up payroll, HST, or import/export accounts. For companies operating within Ontario, understanding how to find or retrieve your Ontario business number is essential for maintaining compliance and ensuring smooth business operations.

BN Number For a Corporation

Upon incorporation, the Canada Revenue Agency (CRA) automatically assigns every business an Business Number (BN). This number serves as the corporation’s unique tax identifier, streamlining all related tax processes.

BN Number For a Registered Business

With a registered business, the CRA now automatically issues a BN, however, the tax filings are still done under the individual owner/s. If any additional CRA program accounts, such as Payroll, HST or Import/Export, are needed, this BN would be used to create these accounts.

When registering directly through CRA they will send all new BN numbers by mail once generated. You can typically expect to receive this within 1-2 weeks after registering. If you have recently registered or incorporated but did not receive your BN, or you can no longer find the BN that was previously sent to you, Ontario Business Central can assist with looking up this information for an Ontario corporation or business name registration, a Federal corporation or a B.C. corporation.

BIN Number vs BN Number, What is the Difference?

In the Province of Ontario, there are two very similar numbers that can be assigned to a business.  One is the BIN (Business Identification Number) number which is a 10-digit number attached to a Business Name Registration (Previously a 9-digit number for Master Business Licence registrations), whether it be a Sole Proprietorship, Firm Name for a General Partnership or Business Name for a Corporation (formerly called a Trade Name under a corporation).  The Ontario BIN number is a unique 10-digit number assigned to the registration. Alternatively, there is a 9-digit tax number with the Canada Revenue Agency called the BN number.  The BN number is only applicable when you are applying for HST, Payroll etc. If you are confused by the difference between these two numbers, you are not alone, and we are here to assist.

The reasons for a BN number for a Business Name Registration formerly a Master Business Licence are as follows:

  • Tax accounts such as HST, Payroll, Import Export
  • Grants and some funding programs
  • Wholesale licensing
  • Many municipal services

We can assist you with obtaining the BN number when you register your business with us.
