A transit number is a code that identifies which branch of your bank holds your account
A transit number is a five-digit code that tells other banks and financial institutions exactly which branch of your bank you use. When someone sends you money through electronic transfer, or when you set up automatic payments, the transit number routes that money to the right location. Without it, a transfer could get lost or delayed because your bank has hundreds of branches across the country.
You'll also hear this called a branch number or sort code, depending on the country and the bank. In Canada, where the system is most standardized, transit numbers are always five digits. The first two digits identify the bank itself, and the last three identify your specific branch.
The transit number is different from your account number (which identifies your specific account) and your bank's routing number (which is used in the United States). If you're moving money between Canadian banks, you need the transit number. If you're receiving money from the US, you'll need a routing number instead.

Where to find your transit number
The easiest place to find your transit number is on a cheque from your account. Look at the bottom left corner of the cheque. You'll see a series of numbers printed there. The transit number is the first five digits, followed by your account number.
If you don't have a cheque handy, log into your online banking portal. Most banks display your transit number alongside your account number in the account details section. You can also call your bank's customer service line and ask them to read it to you—they'll verify your identity first and then provide the number in seconds.
Some banks print the transit number on your debit card or in your welcome package, though this is less common. If you're unsure where to look, your bank's website usually has a help section that walks you through finding it.
When you actually need to provide your transit number
You'll need your transit number whenever someone or something needs to send money directly into your account. The most common situations are direct deposit from your employer, automatic bill payments you set up with utilities or insurance companies, and transfers from other people using their online banking.
If you're receiving a wire transfer from outside Canada, you won't use a transit number—you'll use your bank's SWIFT code or routing number instead. Similarly, if someone is paying you through a payment app like Interac e-Transfer, you typically don't need to provide a transit number; you just share your email address or phone number.
When you're the one sending money to someone else, you'll need their transit number and account number to set up the transfer in your own online banking. Some banks also ask for the recipient's full name to match against their account.
How transit numbers are structured
Every transit number follows the same five-digit pattern. The first two digits represent the bank code—for example, Royal Bank of Canada always starts with 00, TD Bank starts with 04, and Scotiabank starts with 02. These codes are assigned by Payments Canada, the organization that oversees the Canadian payments system.
The last three digits represent your specific branch. A large city might have multiple branches of the same bank, each with a different three-digit code. So if you bank at the Royal Bank branch on King Street in Toronto, that branch has a different three-digit code than the Royal Bank branch on Bloor Street, even though both start with 00.
This structure means you can tell which bank someone uses just by looking at the first two digits of their transit number. It also means that if you move to a different branch of the same bank, your transit number will change because the last three digits will be different.
What happens if you provide the wrong transit number
If you give someone an incorrect transit number, the transfer will usually be rejected before it goes through. The receiving bank's system will recognize that the transit number doesn't match any real branch, and the money will bounce back to the sender. This can take a few business days, which is frustrating but not permanent.
In rare cases, a wrong transit number might route the money to a different branch of your bank. If this happens, the money will eventually reach your account, but it may take longer because the receiving branch has to figure out where it's supposed to go. Call your bank when ready if you think money was sent to the wrong branch—they can usually track it and redirect it faster than waiting for the system to sort it out.
If you consistently provide the wrong transit number to your employer or a regular payment source, the payments will keep failing. Update the information as soon as you realize the mistake, and ask the sender to retry the transfer once you've corrected it.
Transit numbers versus other banking codes you might need
It's straightforward to confuse a transit number with other codes your bank uses. Your account number is unique to your account alone—no one else at your bank has the same account number. Your routing number is used for transfers within the United States and is different from a transit number. Your bank's SWIFT code is used for international transfers and is usually eight or eleven characters long.
Some banks also use an institution number, which is the same as the first two digits of your transit number—it identifies the bank itself, not the branch. When you're setting up a transfer, the form will usually tell you which code you need. If you're unsure, ask the person or organization requesting the information what code they're looking for.
Your IBAN (International Bank Account Number) is used for transfers to Europe and other countries that use the IBAN system. Canada doesn't use IBANs, so you won't need one for domestic transfers, but you might need one if you're sending money internationally.
Frequently Asked Questions
Do I need my transit number to use my debit card or withdraw money from an ATM?
No. Your transit number is only needed for electronic transfers and direct deposits. You can use your debit card and withdraw cash without ever knowing your transit number. It's only relevant when money is being routed electronically from one bank account to another.
What if I moved to a different branch of the same bank?
Your transit number will change because the last three digits identify your specific branch. You'll need to update your transit number with your employer, bill payment providers, and anyone else who sends you money regularly. Your account number usually stays the same, but always confirm with your bank.
Can someone steal money from my account if they have my transit number?
No. A transit number alone is not enough to access or withdraw from your account. Someone would also need your account number, and even then, they can only send money out if they have authorization to do so. Your transit number is meant to be shared—it's not secret information like your PIN or password.
Is a transit number the same in Canada and the US?
No. Canada uses transit numbers; the United States uses routing numbers. They serve the same purpose but are different systems. If you're receiving money from a US bank account, you'll provide a routing number, not a transit number.
What if my bank doesn't have a transit number?
All banks operating in Canada have transit numbers assigned by Payments Canada. If your bank is Canadian and you have a chequing or savings account, you have a transit number. Some online-only banks or credit unions might structure their numbers differently, so call them directly if you can't find it on a cheque or in your online portal.
