If you've lost your Social Insurance Number (SIN) in Canada, it's crucial to take immediate action to prevent identity theft. This article will guide you through multiple ways you can retrieve your lost SIN.

Option 1: Request a SIN Confirmation Letter

One of the easiest ways to retrieve your lost SIN is to request a SIN confirmation letter from Service Canada. Here are the steps:

Note: The online system has its operating hours—usually 6 AM to 3 AM, Eastern Standard Time.

Option 3: In-Person at a Service Canada Centre

If you prefer in-person assistance, you can go to a Service Canada Centre. Here's how:

• Locate your nearest Service Canada Centre using their website.
• Bring the essential original documents that identify you. For example, your valid Canadian passport.
• Speak to a representative and request assistance retrieving your lost SIN.

Bear in mind that due to COVID-19, some locations require book appointments in advance.
