Social Insurance Number – Newborn registration

Parents can use the Newborn Registration Service to complete their child's Birth Registration and apply for their child’s Social Insurance Number (SIN). With this integrated application, parents no longer have to deal with different levels of government and repeat the same information in separate applications.

When applying through the Newborn Registration Service, you should receive your child's SIN in the mail within 10 business days from the date your child's application was processed by the province. If more than 15 business days have passed and you would like to find out the status of your application, contact the SIN program.

You must be the parent of the child and a Canadian citizen or permanent resident to use this service. If you are not a Canadian citizen or permanent resident, you may still be eligible but you will need to visit a Service Canada Office to apply for your child’s SIN.

This service is available in all Canadian provinces, but is not currently available in the territories. For parents living in the territories, consult Section 3: What you need before you apply for your child’s SIN.


  • For all provinces except Quebec, the confirmation of SIN letter will reflect all the names provided on the birth registration form.
  • For Quebec, the confirmation of SIN letter will reflect the "usual given name" and "surname" provided on the Application for Simplified Access to Birth−related Government Programs and Services form. If you need to modify the name on your child’s confirmation of SIN letter, you will need to apply for your child’s SIN in person at a Service Canada office.
