Social Insurance Number
The Social Insurance Number (SIN) is a nine-digit number that you need to work in Canada or to have access to government programs and benefits.
Service Canada offers the Newborn Registration Service, which is an integrated birth registration and SIN application process. This service is available for parents living in Alberta, British Columbia, Manitoba, Nova Scotia, Ontario, Prince Edward Island, Québec, and Newfoundland and Labrador.
To apply for your SIN, please visit a Service Canada Centre with your original primary documents.
NOTE: Special measures are in place to accommodate individuals who cannot apply in-person at a Service Canada Centre. These include submitting applications via Service Canada outreach services or requesting a third party to submit the application in-person on their behalf. Individuals living in remote areas can contact Service Canada at 1‑800‑206‑7218 (select Option #3) to obtain information on how to submit an application by mail.
Service Canada strongly encourages individuals to apply in-person. By doing so, if your application is in order, you can obtain your SIN in less than 15 minutes and do not need to part with your original identity documents.
