When to Submit an an Update Social Insurance Number (SIN) Request

  • A client’s SIN is incorrect on file and needs to be updated.
  • A client provides new SIN documentation to replace or correct the existing SIN.

How to Submit an an Update Social Insurance Number (SIN) Request

To submit an Update SIN request, use the Service Extension on the client’s CRM Contact Record. When submitting the request, there are two distinct submission methods and workflows: Manual Submission, which involves uploading a scanned or physically signed document, and Straight-Through Processing (STP), which automatically generates the required forms and sends them to the client through DocuSign.

Although both methods are valid, we strongly recommend using Straight Through Processing whenever possible for real-time tracking, reduced errors, and faster turnaround times.
