Getting Your Social Insurance Number (SIN)
A Social Insurance Number (SIN) is a nine-digit number you need to work in Canada and to get government benefits and services.
What You Need Before You Apply 📝
To get a SIN, you must provide a valid primary document that proves your identity and legal status in Canada.
You will need one of the following:
- For permanent residents: Your Permanent Resident card (PR card) or your Confirmation of Permanent Residence (COPR) if you arrived in the last year.
- For temporary residents: Your work permit, study permit, or visitor record that says you can work in Canada.
You also need a document that proves where you live (your proof of address). This can be a government letter or a bill with your name and address on it. If the name on your document is different from the name you are using now, you will need a supporting document, like a marriage certificate.
How to Get Your SIN ✅
Applying for your SIN is free. You can choose one of three ways to apply.
-
Gather your documents. Have your original primary document, proof of address, and any supporting documents ready. For online applications, you will need digital copies.
-
Apply online. This is often the fastest method. You will upload your documents on the Government of Canada website. You will get your SIN by mail.
-
Apply in person. 🏢 You can visit a Service Canada Centre. Bring your original documents with you. If everything is correct, you will get your SIN during your visit.
Once your application is approved, you will receive a letter with your SIN. Keep this number safe and do not share it unless it is necessary, for example, with your employer.
