Business Number vs Corporate Number

What is the difference between your business number and corporation number?

The business number is a 9-digit number assigned by the Canada Revenue Agency (CRA) and is part of a unique federal government numbering system. The business number is used to interact with other federal, provincial and even municipal authorities and/or regulators. The business number forms the beginning of your businesses payroll and sales tax numbers as well.

On the other hand, the corporation number refers to a number assigned by Corporations Canada or the provincial ministry at the time of incorporation. This number can be found in the company’s Certificate of Incorporation.
