Don’t carry your SIN card with you unless you know you will have to show it that day, for example, when starting a new job. Store your card safely, for example, in a secure file cabinet at home or in a safety deposit box.
Never use your SIN card as a piece of identification. Doing so puts your SIN and personal information at risk.
Don’t provide your SIN over the phone unless you make the call and you know with whom you are dealing.
Never reply to e-mails that request personal information such as your SIN.
Protect your personal information and your SIN. For example:
shred all paper records containing personal information once you no longer need them
use confidential passwords that contain a combination of upper and lower case characters, numbers and symbols
never use automatic login features that save user names and passwords on your computer
use a personal firewall and anti-virus software on your computer system.
5。SIN卡如果丢失或被盗，应该做什么？
Report the loss or theft of your SIN card to the police. Ask for the case reference number, and the officer’s name telephone number.
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. Contact information:

7。如果我的SIN号码是9开头的，怎么在到期日前更新？
Social Insurance Numbers (SINs) that begin with a "9" are issued to temporary workers who are neither Canadian citizens nor permanent residents. These SINs are temporary and valid only until the expiry date printed on the front of the card.
If you are a holder of a SIN card that begins with a "9", it is important that you renew your SIN card to ensure that the expiry date always corresponds with the expiry date on your document from Citizenship and Immigration Canada authorizing you to work in Canada.
If you are an employer, learn more about your responsibilities related to your employees' SINs.
