Understanding Your Canadian Bank Account Number

Updated March 2026 · 10 min read

Every Canadian bank account has three identifying numbers: the transit number, the institution number, and the account number. Together they form your complete banking coordinates — used for direct deposits, bill payments, wire transfers, and pre-authorized debits. Here's exactly what each number means and where to find it.

The Three Parts of a Canadian Bank Account Number

Transit Number (5 digits)

The transit number identifies the specific branch of the bank where your account was originally opened. Even if you primarily bank online, your account is still associated with a home branch. If you opened your account at the TD branch on King Street West in Toronto, that branch has a specific 5-digit transit number. Transit numbers are assigned by the Canadian Payments Association (Payments Canada).

Note: When you see a 9-digit routing number in Canada (used for some cross-border transactions), it's formatted as a leading zero, followed by the 3-digit institution number, followed by the 5-digit transit number: 0IIITTTTT.

Institution Number (3 digits)

The institution number (also called the bank code or financial institution number) identifies which bank holds your account. These are standardized across Canada:

Account Number (7–12 digits)

Your account number is the unique identifier for your specific account at your specific branch. Most Canadian banks use 7-digit account numbers, though some use up to 12 digits. The account number — combined with the transit and institution number — uniquely identifies your account within the Canadian banking system.

How to Find Your Account Number

Method 1: On a void cheque

The bottom of a Canadian cheque displays your numbers in MICR (Magnetic Ink Character Recognition) format. Reading left to right: cheque number, transit number, institution number, account number. The standard format at the bottom of a cheque is: [cheque#] [transit][institution] [account#]. See our void cheque guide →

Method 2: Online banking portal

All major Canadian banks display your transit, institution, and account numbers in the account details or "direct deposit" section of their online banking portal. Log in, select your chequing account, and look for "account details" or "direct deposit information."

Method 3: Bank statement

Your monthly paper or digital bank statement displays your full account number at the top of each page.

Method 4: Bank mobile app

Most bank apps have a "set up direct deposit" or "share account information" feature that displays your full banking coordinates including a pre-formatted direct deposit form.

Format for Direct Deposit Forms

When filling out a direct deposit form (for CRA, employer payroll, or government benefits), you'll typically be asked for:

1. Financial institution name and address
2. Transit number (5 digits)
3. Institution number (3 digits)
4. Account number (7–12 digits)
5. Account type (chequing or savings)

Some forms ask for a "9-digit routing number" — this is the transit and institution number combined in the format 0-[institution]-[transit]. See our routing number guide →

Are Account Numbers the Same as Card Numbers?

No. Your debit card number is a 16-digit payment network number (Visa Debit or Interac) that links to your account but is not the same as your account number. Your account number (7–12 digits) is your internal banking identifier. Never share your full debit card number when asked for a bank account number — they serve different purposes.

Security — Keep Your Account Number Safe

Your bank account number (transit + institution + account) is used to set up pre-authorized debits — anyone with your account number could potentially set up withdrawals from your account if they also have your banking institution name. Be careful where you share this information and monitor your account regularly for unauthorized transactions. Learn more about safe direct deposit setup →
