What should I do if my SIN card has been lost or stolen?
If your Social Insurance Number (SIN) card has been lost or stolen, it is important to be aware that someone could try to use your Social Insurance Number.
We recommend that you follow these steps to protect your SIN:
- Carefully review your bank account, credit card and other financial transaction statements. If anything concerns you, contact your financial institution.
- Monitor your mail for any disruption in delivery.
- Call Canada’s two national credit bureaus. Ask for a free copy of your credit report and review it for any suspicious activity. You may also wish to see if your credit file should be flagged to indicate that your personal information has been put at risk and may be vulnerable to fraud.
- Report the theft of your SIN card to the police, if you suspect your SIN card is used fraudulently. Ask for the case reference number, the officer’s name and telephone number.
If you suspect someone is using your SIN, consult our Web section for more information on how to deal with SIN fraud.
