How do I replace my lost or stolen confirmation of SIN letter or SIN card?
- There is no fee to apply for a Social Insurance Number (SIN).
- On March 31, 2014, Service Canada began issuing SINs in paper format (confirmation of SIN letter). Production of the plastic SIN cards has stopped.
If your confirmation of SIN letter or SIN card was lost or stolen, you can request a confirmation of your SIN. For more information on how to obtain a confirmation of your SIN, refer to: How do I apply for a SIN?
If you suspect that someone is using your Social Insurance Number (SIN), please see What should I do if I suspect someone is using my SIN?
What should I do if I don't remember my SIN?
If you don't remember your SIN, you can refer to your income tax return where your SIN can be found.
