One Business, One Number- CRA identifier

Currently, government programs use different means to identify business clients. This results in businesses having to use multiple identifiers when dealing with government. For instance, businesses are issued distinct identifiers when they register their business, open a workers’ compensation account, or obtain a liquor license.


The Common Business Number is a unique number already issued by the CRA to every Canadian business for federal income tax purposes. By adopting the Common Business Number, businesses will be able to conveniently identify themselves to participating government programs using a single business identifier.
