T2125 Business Identification: Business Number, Address/House Number, or SIN?

[justin14]

This may be a silly question, but I am currently trying to fill out the "Business Identification" section for the T2125 using the online return and I would like some clarification regarding what the "Number" box is referring to.

(Please see attached image)

I initially thought that "Number" was referring to a business number, which I do not have as I am a self-employed sole proprietor working under my own name. The page shows that I am required to fill out the "Number" section if I also have filled out the "Street, P.O box" section. This made me question whether or not "Number" is actually referring to a business number, or if it is referring to the house/unit number of the address.

If "Number" is really referring to a business number, would I need to input my SIN instead, seeing as I don't have a registered business?

Thanks.

This refers to the street number, the address of your business.  In most cases for a self employed person it is there own address.
