Did you know
If you are a Canadian citizen, a newcomer to Canada, or a temporary resident, you need a Social Insurance Number (SIN) to work in Canada or to receive benefits and services from government programs.
A SIN is issued to one person only. It cannot legally be used by anyone else. You are responsible for protecting your SIN. Store any document containing your SIN and personal information in a safe place—do not keep it with you.
For more information on how to protect your SIN, please see our publication, Your Social Insurance Number: A Shared Responsibility!
Applying at a Service Canada Centre
Service Canada has made it easy for you to apply for a SIN, to request a confirmation of your SIN, or to amend your SIN record. When applying in-person, you do not have to complete an application form nor do you have to mail your original proof-of-identity documents.
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.
- 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 our website at servicecanada.gc.ca 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 and 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
If you do not meet the above mentioned criteria to apply by mail and it is not possible for you to apply in person at a Service Canada point of service, there are alternate options which include having another individual submit your application for you in person.
If you currently reside 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 required to apply for a SIN
Whether you apply in person or by mail, you must provide original primary proof of identity documents to prove your identity and legal status in Canada. Photocopies are not accepted. You may also need to provide supporting proof of identity documents if the name indicated on your primary proof of identity document is different than the name you are currently using. If you are a parent, a legal guardian, or a legal representative applying on behalf of an individual, you must provide additional documents; refer to the list provided below.
When applying in person, your original documents will be returned to you immediately.
All documents must be written in English or French or accompanied by an official translation attested to by the translator before a notary public, or prepared by an officer of a foreign government or an official of the British or Canadian Consulate.
What is a primary proof of identity document
A primary proof of identity document is an official document that proves your identity and status in Canada. We need to see an original of this primary proof of identity document.

Note: The Confirmation of Permanent Residence is acceptable if used within one year of the date you became a permanent resident. The Permanent Resident card is required after this period
- a Record of Landing issued by CIC before June 28, 2002
- a Verification of Landing issued by CIC. This document is only acceptable to amend a SIN record or to obtain confirmation of an existing SIN or

- a letter confirming eligibility for pension or benefits from Canada Pension Plan (CPP), Old Age Security (OAS) or Régie des rentes du Québec (RRQ)
What is a supporting proof of identity document
A supporting proof-of-identity document is a legal document and is required if the name on your primary proof-of-identity document is different than the name you currently use. You must provide one of the following supporting proof-of-identity documents with your request, if required:
- a certificate of marriage, record of solemnization of marriage, or marriage statement to support your family name after marriage. Note: This does not apply to Quebec residents who got married after April 1, 1981, regardless of where they were married

Applying for a SIN on behalf of someone else
Parents or legal guardians can apply for a SIN on behalf of a minor child. Children who are 12 years of age or older can apply for their own SINs. If you are applying on behalf of a child in-person at a Service Canada point of service, you must provide:
- the child's original proof-of-identity documents
- your own SIN or original document if you are applying in-person. If you were never issued a SIN and/or are applying by mail, you must provide your original proof-of-identity documents
If you are a legal guardian, you must provide an original document or certified copy of a document issued by a provincial/territorial authority that confirms your legal guardianship (in Quebec, a notarized will is an acceptable document).
Legal representatives applying on behalf of a minor child or an adult can apply for a SIN for a minor child or an adult. If you are a court appointed lawyer or individual, or a provincial/territorial employee applying on behalf of a child or adult in-person at a Service Canada point of service, you must provide:
- the original proof-of-identity documents of the person for whom you are applying
- your own original valid employee photo identification or government-issued identification
- an original document or certified copy of a document issued by a provincial/territorial authority that confirms your legal guardianship or representation (in Quebec, a notarized will is an acceptable document)

(Note: for court appointed lawyers or court appointed individuals such as family members, this letter is not required).
