If you live in Canada
Applying at a Service Canada Centre
Bring all the necessary documents to the nearest Service Canada Centre. If everything is in order, you will get a SIN during your visit.
Applying by mail
Normally you must apply for a SIN in person, or have someone else apply for you in person. However:
- if you live in a remote area with no Service Canada Centre within 100 km, you are eligible to apply by mail. To confirm this is the case, you can use your postal code to check your eligibility on the Service Canada website or call Service Canada at 1-800-206-7218 (select option 3).
- if you are unable to apply in person or to have someone else apply for you in person, you may be eligible to apply by mail. You must call Service Canada at 1-800-206-7218 (select option 3) in order to find out if you can apply by mail.
If you do not live in Canada
You are eligible to apply by mail. In order to apply, consult the Application for a Social Insurance Number – Information Guide for Applicants.
When you apply for a SIN, you must provide a valid original primary document to prove your identity and legal status in Canada. If the name on your primary document is not the name you are currently using, you may also need to provide a valid supporting document.
If you are applying for someone else, you may need to provide additional documents.
Important: All documents must be valid originals. Photocopies are not accepted.
Acceptable primary documents
Canadian citizens must provide one of the following documents:
- Birth certificate (also known as Certificate of birth) issued by the province or territory in which you were born.
- In most cases, original birth certificates (certificates of birth) 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.
- Service Canada does not accept Quebec proof of birth documents issued before 1994.
- Certificate of Canadian Citizenship issued by Immigration, Refugees and Citizenship Canada (IRCC) or Citizenship and Immigration Canada (CIC).
- Certificate of Registration of Birth Abroad issued before 1977 by CIC.
Note: If you have Indian status under the Indian Act and you want to register your status in your SIN record, you must provide your primary document and a Certificate of Indian Status issued by the Government of Canada
Permanent residents must provide one of the following documents:
- Permanent resident card issued by IRCC or CIC.
- Confirmation of Permanent Residence issued by IRCC, accompanied by either a travel document (for example, a foreign passport) or an alternate photo identification issued by a provincial/territorial authority (for example, a driver’s licence).
Note: You can use the Confirmation of Permanent Residence within 1 year of the date you became a permanent resident. After that you must use the permanent resident card.
- Record of landing issued by CIC before June 28, 2002.
- Verification of Landing issued by IRCC or CIC when an original Record of Landing or the Confirmation of Permanent Residence is not available (if it has been lost, for example). This document is acceptable only to update a SIN record or confirm an existing SIN.
- Status Verification or Verification of Status issued by IRCC or CIC. This document is acceptable only to update a SIN record or confirm an existing SIN.

- states that the permit holder “may accept employment” or “may work” in Canada; or
- is accompanied by a “confirmation to work off campus” letter issued by IRCC or CIC before February 11, 2015.
Note: If neither of these requirements is met, you may contact IRCC to ask if you are eligible to apply for an amended study permit.
- visitor record issued by IRCC or CIC, stating that you are authorized to work in Canada or that was issued under:
- Regulation 186 (except for R186[a] – see Note)

- Regulation 19 of the repealed Immigration Act; or
- issued to a member of the clergy.
Note: Anyone who comes to Canada under Regulation186 (a) as a “business visitor” is not entering the Canadian labour market, so they cannot get a SIN.
- diplomatic identity card and a work authorization note/letter issued by the Department of Foreign Affairs, Trade and Development.
Acceptable supporting documents
- certificate of marriage, record of solemnization of marriage, marriage statement or a document with a similar name — to support your family name after getting married
