Open KOHO Free — Code 45ET55JSYAA Social Insurance Number (SIN) is a 9-digit number issued by Service Canada. It is the cornerstone of your identity in the Canadian financial and tax system. You need your SIN to:
Your SIN is highly sensitive — treat it like a password. Only share it when legally required (employer, bank, government agency). Never carry your SIN card in your wallet.
| Category | Eligible | SIN Starts With |
|---|---|---|
| Canadian citizens | Yes | 1–8 |
| Permanent residents | Yes | 1–8 |
| Work permit holders | Yes (authorized to work) | 9 |
| Study permit with work authorization | Yes | 9 |
| Protected persons / refugees | Yes | 1–8 or 9 |
| Visitors / tourists | No | N/A |
If you are in Canada on a temporary basis — work permit, study permit, or certain other permits — your SIN will begin with the digit 9. This is entirely normal and does not affect your ability to work or bank. However, a SIN beginning with 9 has an expiry date linked to your permit. When you renew or change your permit, you must update your SIN at Service Canada.
When your temporary SIN expires and you become a permanent resident, you will receive a new SIN beginning with a different digit. It is important to update this with your employer and financial institutions promptly.
You must apply in person at a Service Canada Centre. There is no online application for newcomers at this time. Here is what to do:
| Immigration Status | Primary Document | Secondary Document |
|---|---|---|
| Permanent Resident | PR card or COPR + passport | Passport |
| Work Permit | Work permit | Passport |
| Study Permit | Study permit + letter from school | Passport |
| Convention Refugee | Protected person decision letter | Travel document or passport |
Legally, you should apply for your SIN within 3 days of starting work. However, you can open a basic bank account before receiving your SIN — most Canadian banks accept newcomers with a passport and immigration document alone. Once your SIN is issued, provide it to your bank so they can register your account for tax reporting purposes.
KOHO is an excellent option while you wait for your SIN — you can apply online using just your passport and start banking immediately. Your SIN can be added to the account later.
SIN fraud is a significant problem in Canada. Fraudsters use stolen SINs to file false tax returns, open fraudulent credit accounts, and collect government benefits. Protect yourself by never emailing your SIN, never sharing it over the phone unless you initiated the call, and regularly checking your credit report at Equifax and TransUnion for unfamiliar accounts.
KOHO accepts newcomers with no credit history. Code 45ET55JSYA = $20 welcome bonus.
