when should i give my sin number

Some government organizations or private businesses ask for the SIN because it is a simple way to identify you.Many use it as a client account number so that they don't have to set up their own numbering system.ou do not have to give your SIN when you: 1  Apply for a job (before you are hired). 2  Apply for a rental home. 3  Negotiate a lease with a landlord. 4  Apply for a credit card. 5  Rent a car. 6  Sign up for a cell (mobile) phone. 7  Apply for a video club membership.
