With Update, you need to submit an application and the necessary paperwork in order to update your SIN record. You will receive a letter confirming your SIN after Service Canada makes the necessary modifications.
Receiving this mail confirms that the modification has been made even though your SIN remains unchanged.
Receiving your SIN and updating your SIN Record
Service Canada stores your personal information in the Social Insurance Register. This information includes:
- Your SIN
- Your name
- Your date of birth
- Your place of birth, and
- Your parents’ names
Updating information linked to your existing SIN
To update your SIN record, you must submit an application and the required documents. Once Service Canada makes the changes, you will receive a Confirmation of SIN letter. Your SIN stays the same, but receiving this letter indicates that the change has been made.
If you are legally changing your name
By law, you must update your SIN record when you change your name. To do this you will need to submit an application and the required documents.
If you would like to have your disc number removed from your SIN record
To remove your disc number from your SIN record, submit an application and the required documents in person, by mail or online.
If you are moving
You do not need to notify the SIN Program about a change of address, unless you are waiting to receive a Confirmation of SIN letter.
If you are changing your gender designation
You may now choose to have your gender marked as “X” or choose to not declare your gender. Service Canada will add a note to your record with your choice. Please note, until our computer systems are upgraded to register this information, “male” or “female” will still appear on your SIN record.
To make any changes to your SIN record, you will need to submit an application and the required documents.
