Once you have a SIN

Protect your SIN

Your SIN is confidential and . You should be cautious about providing your SIN to people you do not know, including over the phone to suspicious callers.

If an organization asks for your SIN and it is not legally required, you can explain that you prefer not to provide it and offer different proof of identity.

Know your SIN

As an international student, you are a temporary resident of Canada, so your SIN begins with a 9 and should be valid for the same duration as your Canadian immigration document.

Expiry and extensions

If you apply to extend your temporary resident status in Canada before your Canadian immigration document expires, and your current document expires before you receive the new document, you will probably have  (previously known as “implied status”).

• if you are in Canada with maintained status, you may be allowed to continue studying or working until you receive your new document from IRCC, provided that you applied to extend your status in Canada before the expiry date and you have not left Canada

You will need to update your SIN record with Service Canada once you receive the new document from IRCC. The process is the same as in the initial application. You will receive a new Confirmation of SIN letter with an updated expiry date to match your new immigration document.
