How can I protect my SIN?
There are a number of things you can do to protect your SIN:
- Provide your Social Insurance Number only when you know that it is legally required.
- Store any document containing your SIN and personal information in a safe place—do not keep it with you.
- Contact Service Canada if you change your name, if your citizenship status changes, or if information on your SIN record is incorrect or incomplete.
- Take immediate measures to protect your SIN when you suspect someone else is using your SIN fraudulently.
