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.
There is no fee to apply for a Social Insurance Number (SIN).
On March 31, 2014, Service Canada began issuing SINs in a paper format (confirmation of SIN letter). Production of the plastic SIN cards has stopped.
SIN cards that are not expired and are currently in circulation can still be used.
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 any of the provinces. Service Canada requires 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 proof of identity documents. To apply for your SIN, please visit a Service Canada Centre with your original proof of identity documents.
