How To Apply For A Business Number In Canada

Business Number (BN) is a nine-letter number selected by the Canadian Revenue Agency (CRA).

It is used as a standard identifier for businesses to facilitate business interaction with the federal, provincial, and municipal governments.

As OCI works with partner funding agencies, OCI must adhere to provincial government standards.

Business Number only applies to people who run a business (sole proprietors) and partnerships if your business is merged. Not all companies truly require a BN.

You only require a business number if you need a system account to deduct certain taxes such as GST / HST, tax deductions, import duties, fill out information returns, etc.

Who Can Apply for a Business Number?

Any client required to conduct business with the CRA and any partner who has taken over BN must register with BN. Business registration operates under the one business number BN administrative policy.

An entity is granted only one BN regardless of the number of business premises or businesses owned by that business.

Business is defined as the sole ownership of land, a partnership, a company, a trust, a government, or any other organization that identifies it as a charity.

BN registration is not limited to commercial businesses. So, for example, a customer who deducts the deduction from their nanny will not be considered a commercial entity but may still be able to sign up for BN.

Required Documents for Business Number Registration

You will need these documents to register your business:

  • Business ID type (single owner, trust, or partnership)
  • Owner information, including name, social insurance number, occupation, and contact number
  • Personal contact details
  • The official name of the business and its trade or operational name
  • Business location
  • Great business activity
  • The type of system accounts you need

Work of Canadian Intellectual Property Office About Business Number

The Canadian Intellectual Property Office (CIPO) collects BN in compliance with the Canadian Treasury Board Secretary’s Order of Business Number, which directs government programs that provide businesses to collect BN as a standard business identifier.

It is an essential step in a successful business partnership with the government.

BN is a solid incentive to “tell once” about making the government increase service efficiency and improve system integrity, leading to a faster access to services, more crowded forms, and integrated business service delivery.

As CIPO modernizes customer-centered services, it will add a platform for business numbers to client-assisted forms and intellectual property and registration forms.

Government Departments that Collect Business Numbers

All business department departments are expected to use BN as a business-specific identifier under the Business Number Order. In addition, BN is used by eight provinces, even at the municipal level, with the City of Winnipeg.

Sectors within the Canadian Department of Economic Development and Development Science have adopted BN, such as Corporations Canada, Measurement Canada, Competition Bureau, and CIPO.

Benefits of Acquiring a Business Number

In the meantime, businesses should repeat the same identification information when registering for programs. In addition, companies need to manage multiple identifiers and communication systems to update their information.

Once fully utilized, BN will make it easier for businesses to contact provincial or state departments regarding their accounts.

In addition, BN facilitates business communication with the government, as business owners will eventually be recognized in various areas of the government system by their business numbers.


Giving a BN is voluntary. However, if you have a BN, it is highly recommended to provide it when working with CIPO.

For Quebec Businesses and GST / HST program accounts, Revenu Québec generally manages the GST / HST.

Therefore, if your business location is in Quebec, you must complete your returns at Revenu Québec using its forms unless you are a designated financial institution (SLFI) for GST / HST or QST purposes.
