Can I apply for a SIN online in Canada?

Online SIN applications are only available in limited circumstances: specifically for newborns through the Newborn Registration Service (offered by some provinces at birth registration) and for replacing a lost SIN letter. Most applicants must apply in person or by mail.

What documents do I need to get a SIN in Canada?

You need one primary identity document. For Canadian citizens: birth certificate or Canadian passport. For permanent residents: Permanent Resident card or Confirmation of Permanent Residence (COPR). For temporary residents: work or study permit and a valid foreign passport. You may also need a secondary document if your primary document doesn't show your address.

Is there a SIN card in Canada?

No. Canada stopped issuing physical SIN cards in 2014. Instead, ESDC issues a SIN confirmation letter, which is the official document showing your Social Insurance Number. Treat it with the same care as you would a SIN card — your SIN should never be shared unnecessarily.

What is a temporary SIN (starting with 9)?

A SIN beginning with the number 9 is a temporary SIN issued to temporary residents (those with a work or study permit). It is valid only as long as your immigration status is valid and must be renewed when your permit is renewed. Employers are required to track the expiry date of a 9-series SIN.

How Long Does It Take to Get a SIN in Canada? (2026)

Q: How long does it take to get a SIN in Canada?

In-person at a Service Canada office, you receive your SIN number verbally on the same day and a confirmation letter within 4–5 weeks. If you apply by mail, allow 4–6 weeks to receive the SIN letter. There is no physical SIN card — Canada stopped issuing SIN cards in 2014.

Your Social Insurance Number (SIN) is a 9-digit number issued by Employment and Social Development Canada (ESDC) that you need to work, file taxes, and access most government programs. Getting one is straightforward — and if you apply in person, you’ll have your number the same day.

SIN Application Timeline by Method

Method	When You Get the Number	When You Receive the Letter
In-person at Service Canada	Same day (verbally)	4–5 weeks by mail
By mail	4–6 weeks	4–6 weeks
Newborn Registration (provincial)	Days to weeks	4–6 weeks

Note: There is no physical SIN card. Canada eliminated SIN cards in 2014 and now issues a SIN confirmation letter — an official document on Security Canada letterhead with your SIN. This letter is your proof of SIN.

If you’ve forgotten your SIN entirely and have no letter, you must apply in person with identity documents.

Protecting Your SIN

Your SIN is used by CRA, employers, financial institutions, and government programs — and is a common target for identity theft. Share it only when legally required:

Required to provide your SIN:

Employer (for payroll and T4 reporting)
CRA (for tax filing)
Banks/investment accounts (for T5 and investment income reporting)
RRSP/TFSA providers
Federal and provincial benefit programs

Not required to provide your SIN:

Rental applications
Loyalty programs
Landlords
Most private businesses

If someone requests your SIN without a clear legal reason, ask why they need it and what their privacy policy is.
