Update or confirm a Social Insurance Number
How do I update or confirm my SIN record?
Use Service Canada's SIN guidance to correct a record, report a legal name or status change, or update a temporary document's expiry information. The official contact guide separates these requests from checking an application already submitted. It also points to ways to locate an existing number, which may avoid an unnecessary application.
Where to begin
- Choose the SIN issue that matches your situation on the official page.
- Follow its application or existing-record instructions and document checklist.
- Use the relevant status or contact route if you already submitted a request.
Before you open the official service
- The type of record change needed
- Your previous submission date, if applicable
- The official supporting-document checklist
Keep your actual documents and account details off this website. Use the official service’s current checklist before applying.
What to check for your situation
A change to an immigration document does not itself confirm that a SIN record was updated. Service Canada handles that determination.
Fees, processing times and document rules can change. This page helps you navigate; it does not confirm eligibility or replace the government’s instructions.
