Canadian SIN Number Application Guide for Newcomers
The social insurance number (SIN) is a powerful 9-digit number you will need in Canada. This article will guide you on how to start your SIN number application, how to check your SIN application status, the phone numbers to call if you want to, and what to do if you mistakenly lose your SIN. We will also cover how to renew your SIN number if it expires.
What is a SIN number?
Your Canadian Social Insurance Number (SIN) is a 9-digit number the Canadian government gives to each person. It would help if you had it to be able to legally work in Canada and also have access to Canadian government programs and benefits.
Each SIN number is unique. So nobody can use your SIN number (not your spouse or child). You also won’t be able to use another person’s SIN number. This is why it’s essential to get your SIN number and know how to safeguard it appropriately, which we’ll also cover in this article.
SIN numbers are now issued in paper format by Service Canada. The name of the paper is your “confirmation of SIN letter.”
The government used to give plastic SIN cards, but they’ve stopped it. So if you were issued a plastic card and it hasn’t expired, you can keep using it till it does. Then you apply for a renewal and get your renewed SIN in paper format.
What does it mean when your SIN begins with “9”?
SINs that begin with the number “9” are issued to anyone not in Canada when they apply for the number. This includes those who are not Canadian citizens and those who have not been granted permanent residency.
SINs starting with 9 are usually SIN numbers for students, temporary workers, etc.
Who can get a Social Insurance Number?
If you’re going to Canada, you must get a social insurance number. Those that need a SIN also include:
- Canadian citizens
- Permanent residents
- Some temporary residents (visitors, students, etc.)
- Some refugee claimants and
- Children who are 12 years of age or older
What can you do with your SIN number?
Anyone who wants to study, live and work in Canada must apply for a SIN number. With your SIN number, you will be able to:
- Work and earn money in Canada
- Enjoy student aids
- Reap the harvest from your investments
- Contribute to retirement and pension plans
- Use government services like social assistance, veterans benefits, workers’ compensation benefits, etc.
So if you are migrating to Canada, we advise you to start your SIN number application as soon as possible.
The law in Canada says that you can be asked to present your SIN at any time, so start now so that you will have it when you need it.

Top 8 Ways to Protect your SIN Number

- If you still use the SIN card, keep it in a safe place at home
- Don’t use your SIN as a means of identification
- Only release your SIN only when it is legally required
- Never disclose your SIN over the phone unless you’re sure beyond doubt that it’s legally required
- Never reveal personal information like your SIN over email
- Destroy paper records with your SIN number once you no longer need them (do not recycle)
- Always contact Service Canada if you change your name, your citizenship status, or the information on your SIN record
- Take immediate action if you suspect someone is using it fraudulently using your SIN
What if you lose your sin number
If you lose your confirmation of SIN letter, you can quickly get your SIN number from your income tax return or ask your employer to give you your SIN number. Alternatively, you can apply to Service Canada for another Confirmation of SIN. As we explained above, online, by mail, or in person.
If applying online, change the application type to “Confirmation of SIN.”
