Get a Social Insurance Number

A social insurance number (SIN) is really useful. You need your SIN to get a job, tax refunds, and student loans. 

Do I already have a SIN card?

If you had a Continuing Custody Order (CCO) or were a permanent ward you may have a SIN card. Contact the Public Guardian and Trustee’s office to find out.

You can apply for a SIN card at your local Service Canada Centre or by mail.

In person

1. Go to your local Service Canada Centre.

By mail

If you live 100 km or more from the nearest Service Canada office you can apply by mail.

  2. Find one of these pieces of ID:
    • Canadian birth certificate

Insider Tip

It's a good idea to photocopy your ID before you mail it away. Or, you can just write down your ID numbers. It'll help you get new ID if the original is lost in the mail.
