What is the difference between a BN and a BIN?
The Business Number (BN) is a 9-digit federal client identification number to which businesses can register program accounts. This number should be used when communicating with the Canada Revenue Agency (CRA) about accounts you have or wish to create. For example, if you would like to discuss your GST/HST account or you would like to create a payroll account, you should quote your existing BN. The Business Identification Number (BIN) is also a 9-digit number used by the Ontario government to identify provincial business accounts. It also appears on the Ontario Master Business License and should be used for communications with the Ontario government about your business.
