To apply online you will need to upload copies of at least 3 different documents:

  1. a valid primary document that proves your identity and legal status in Canada, and
  2. a valid secondary document to confirm your identity, and
  3. proof of address

If the name indicated on your primary or secondary document is different than the name you are currently using, you must also provide supporting documents.

If you are applying for someone else, you will need to provide additional documents.

For children over the age of 12 but under the age of majority that are applying for themselves the same requirements apply. If the child cannot provide the 3 required documents, then a representative must apply on their behalf and must follow the instruction for Additional documents required for representatives.

Refer to the list of documents below to determine the proof-of-identity and secondary documents as well as proof of address you are required to submit.

If you are requesting the SIN confirmation to be mailed to an address other than your own, you must apply by mail.

Note: Failure to provide required documentation will result in your application being rejected.

Additional information about the online form

Note: In the online form, items with a star (*) are mandatory.

The information on the application form should match your primary document with the exception of your gender. For gender you have the option to have your gender marked as “X” or not to declare your gender. Service Canada will add a note to your record indicating your choice. However, until our computer systems are upgraded to register this information, “male” or “female” will still appear on your SIN record.

If there are minor variances between the information provided on the online application and the information as it appears on the primary document, the information will be entered in the Social Insurance Registry as it appears on the primary document.

Parents

The parent listed must not be repeated. Parents can appear in any order.

Note: Some provinces have passed legislation to recognize up to 4 parents on the registration of birth and you now have the option to have them all listed on your SIN record. In order to document the parent(s) that do not appear on the application form, submit a separate sheet of paper. On this sheet, provide the given name(s) and the family name at birth of each parent and underline the family name at birth.
