When residing in Canada
All applicants residing in Canada should apply in-person; however, special measures are in place to accommodate individuals who cannot apply in-person at a Service Canada point of service.
Applying at a Service Canada Centre
When applying in-person, gather all the required documents and take them to the nearest Service Canada point of service. If everything is in order, you will get your SIN during your visit.
Applying by mail
- If you live in an inaccessible area or 100 kilometers or more from a Service Canada point of service, you are eligible to apply by mail. If you are unsure if you are eligible, visit the Social Insurance Number page to confirm your eligibility to apply by mail using your postal code or contact Service Canada at 1-800-206-7218 (select option #3).
- If you are unable to apply in person due to other extenuating limitations there are alternate options which include having another individual submit your application for you in person. If you cannot have another individual submit an application in person on your behalf, you must contact Service Canada at 1-800-206-7218 (select option #3) to confirm if you are eligible to apply by mail.
When residing outside Canada
You are eligible to apply by mail. Please consult the Application for a Social Insurance Number – Information Guide for Applicants for more information on how to apply.
Documents needed in order to apply
When you apply for a Social Insurance Number (SIN), you must provide a valid original primary document to prove your identity and status in Canada. You may also need to provide a valid supporting document if the name indicated on your primary document is different than the name you are currently using. There is no fee to apply for a SIN.

If you are applying for someone else, you may need to provide additional documents.
Acceptable primary documents
Canadian citizens must provide an original of one of the following:
- Certificate of birth of birth certificate issued by the province or territory in which where you were born
- In most cases, original certificates of birth and birth certificates are considered acceptable. However, some birth certificates, although they are original documents issued by a vital statistics agency, may no longer be considered valid by the issuing province/territory or meet the requirements for various reasons. Service Canada must review the document to determine its validity.
- We do not accept Quebec proof of birth documents issued prior to 1994
- If you are a registered Indian and you want to register your status in your SIN record, you must provide your birth certificate (see section on Canadian citizens) and a Certificate of Indian Status issued by Indigenous and Northern Affairs Canada or Indian and Northern Affairs Canada

- Record of Landing issued by CIC before June 28, 2002

Note: Clients who are coming to Canada under R186 (a) as “business visitors” are not entering the Canadian labour market and for this reason cannot obtain a SIN.
