A transit number identifies which branch of a bank holds your account

A transit number is a five-digit code that tells you which specific branch of a bank processes your account. It is not the same as your account number or your bank's main routing number. When you write a cheque or set up a direct deposit, the transit number tells the other bank's system exactly which branch to send the money to or pull it from.

In Canada, transit numbers are required on every cheque. In the United States, banks use a different system called the routing number, which serves a similar purpose but covers a wider area. If you are in Canada or dealing with a Canadian bank account, you will see the transit number printed on your cheques and statements.

The transit number appears in a specific place on a cheque: it is the first set of digits printed in the bottom left corner, before your account number. For example, a transit number might look like 12345. The first two digits identify the bank itself, and the last three digits identify the specific branch.

Key Takeaways

  • A transit number is a five-digit code that identifies the specific branch where your bank account is held, not the bank as a whole.
  • Transit numbers appear on the bottom left of Canadian cheques, before your account number, and are required for cheques to process correctly.
  • The first two digits of a transit number identify the bank, and the last three identify the branch location.
  • You will need your transit number when setting up direct deposits, automatic bill payments, or wire transfers to your account.
  • The transit number is different from your account number and your bank's routing number, though all three are needed for different payment purposes.

Where to find your transit number

Your transit number is printed on every cheque you receive from your bank. Look at the bottom left corner of the cheque, where you will see a series of numbers. The first five digits are your transit number. If you do not have cheques on hand, you can find it on your bank statement, usually near your account number in the account information section.

You can also call your bank's customer service line and provide your account number. They will give you your transit number over the phone. Many banks also display it in their online banking portal under account details or account settings. Some banks print it on the back of your debit card, though this is less common.

Why banks need your transit number

The transit number exists because most large banks operate many branches across a country or region. When money moves between accounts, the payment system needs to know not just which bank, but which branch. A cheque drawn on a branch in Toronto needs to route differently than one drawn on a branch in Vancouver, even though both are the same bank.

Direct deposits work the same way. Your employer's payroll system uses your transit number to send your pay to the correct branch. If you give them the wrong transit number, your deposit might go to the wrong branch or be delayed while the bank tries to figure out where it should go. Wire transfers and bill payments also use the transit number to may support money reaches the right place.

Transit number versus routing number versus account number

These three numbers all appear together on a cheque, but they do different jobs. Your transit number identifies the branch. Your account number identifies your specific account at that branch. Your routing number (in the United States) or institution number (in Canada) identifies the bank itself, not the branch.

In Canada, the routing number is actually a nine-digit code made up of the institution number (three digits) plus the transit number (five digits) plus a check digit (one digit). In the United States, the routing number is a nine-digit code that covers a wider geographic area and does not break down into branch-level detail the way a transit number does. If you are sending money internationally or to a US account, you will need the routing number, not the transit number.

What happens if you give the wrong transit number

If you provide an incorrect transit number on a cheque, the cheque may be rejected or delayed. The receiving bank's system will try to match the transit number to a real branch. If it cannot find a match, the cheque will bounce, and you will be notified that the cheque was not processed.

For direct deposits and bill payments, a wrong transit number usually results in the payment being returned to the sender. Your employer or the organization sending the money will contact you to ask for the correct information. The payment does not go through until the correct transit number is provided. This is why it is worth double-checking before you give out your banking details.

Transit numbers for online and mobile banking

If you use online banking or a mobile app, you may not need to think about your transit number at all. When you set up a direct deposit or bill payment through your bank's own system, the transit number is already filled in automatically because the bank knows which branch your account is at.

You only need to provide your transit number manually when you are dealing with another organization—your employer, a government agency, a utility company, or another bank. In those cases, they are asking for it because they need to send money to your account and do not have access to your bank's internal systems.

Frequently Asked Questions

Is my transit number the same as my account number?

No. Your transit number identifies the branch (five digits), while your account number identifies your specific account at that branch (usually 7 to 12 digits). Both appear on your cheque, but they serve different purposes. You need both to receive payments.

Do I need my transit number to use my debit card?

No. Your debit card uses your account number and PIN to process purchases and withdrawals. The transit number is only needed when someone outside your bank needs to send money to your account, such as your employer or a government agency.

Can my transit number change?

Your transit number can change if you move your account to a different branch of the same bank. If you close your account at one branch and open it at another, the new branch will have a different transit number. Your bank will issue you new cheques with the updated number.

What if I do not have a cheque to find my transit number?

Call your bank's customer service line with your account number, and they will provide your transit number. You can also log into your online banking account and look for account details or account information, where the transit number is usually listed.

Do I need a transit number for international wire transfers?

For transfers to a Canadian account from outside Canada, you may need the full routing number (which includes the transit number) or a SWIFT code, depending on the sending bank's requirements. For transfers to a US account, you will need the US routing number, not a transit number. Ask the organization sending the money which code they need.
