If you are a temporary worker in Canada, your Social Insurance Number will begin with the number 9 and have an expiration date. The expiration date on your SIN card is the same expiration date on your citizenship and immigration documents that authorize you to work in Canada. To renew your SIN when it expires, you must visit a Service Canada Office.
Visit a Service Canada Office
You can search for the nearest Service Canada Office using your zip code, city, province or territory. If you live in an area farther than 100 km, you might be able to mail in your renewal. You can check to see if you qualify on the Service Canada SIN card application page by entering your zip code. If you cannot visit a Service Canada in person and have no one to go on your behalf, you might also qualify for renewal through the mail. Call 1-800-206-7218 and select option number three to see if you meet the requirements.
Bring Identifying Documents
To change the expiration date on your SIN card, you'll need to bring in one primary document. Examples of primary documents for temporary residents include:
- Citizenship and Immigration Canada work permit
- CIC study permit
- CIC visitor record
- Diplomatic identity card and note of permission of employment from Foreign Affairs, Trade and Development Canada

If the name on your primary document is different from the name you go by, you'll also need to provide one supporting document, such as:
- Certificate of marriage
- Divorce decree
- Legal name-change certificate
- Adoption order
- Notarial adoption certificate
