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 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.
Special measures are in place to accommodate individuals who cannot apply in-person at a Service Canada point of service.
Note: Only individuals in these circumstances are permitted to apply by mail:
Individuals living 100 km or more from the nearest Service Canada point of service, in an inaccessible area, or where outreach is very infrequent may apply by mail. To confirm your eligibility to apply by mail, you must verify your postal code.
Individuals with other extenuating limitations preventing them from visiting a Service Canada point of service and cannot use the assistance of another individual to submit an application on their behalf may be eligible to apply by mail. Note: Individuals must contact 1-800-206-7218 (select Option #3) to determine if they are eligible to apply by mail.
