What documents do I need to apply for a Social Insurance Number?

The primary document required is a valid original primary identification document that proves your identity and legal status in Canada, such as a Canadian birth certificate, Canadian passport, or Certificate of Canadian Citizenship. Additionally, you must provide a valid secondary document that supports your identity and legal status, like a provincial or territorial identification card. If you are a non-Canadian applicant, you will also need to submit supporting documents, such as a work permit or study permit. These documents are essential for authentication purposes and to ensure that you meet the eligibility criteria to obtain a SIN.
