A transit number is a code your bank uses to route money between financial institutions
A transit number is a four- or five-digit code that identifies the specific branch of your bank. When you send money to someone else's account or receive a transfer, the transit number tells the banking system which physical location or processing center should handle the transaction. It works alongside your bank account number and your bank's institution number to create a complete routing address for your money.
Transit numbers are used primarily in Canada. In the United States, the equivalent is called a routing number or ABA number. If you bank in Canada or are sending money to a Canadian account, you will need the transit number. If you are in the US, you will use a routing number instead.
You can find your transit number on the bottom left of your cheques, in your online banking portal, or by calling your bank's customer service line. It is not secret information — it is printed on every cheque you write.
Key Takeaways
- A transit number identifies which branch of your bank processes your account, and is required for electronic transfers and direct deposits.
- Transit numbers are four or five digits and appear on the bottom left of your cheques, before your account number.
- You need both your transit number and your institution number (the bank code) to complete a full routing address for money transfers.
- In the United States, the same function is performed by a routing number; transit numbers are specific to Canadian banking.
Where to find your transit number
The easiest place to locate your transit number is on a cheque from your account. Look at the bottom left corner — you will see a series of numbers. The first four or five digits (depending on your bank) are your transit number. The next eight digits are your account number.
If you do not have a cheque handy, log into your online banking account. Most Canadian banks display your transit number alongside your account number in the account details section, sometimes labeled as "branch number" or "transit code." You can also call your bank's customer service number, which is usually on the back of your debit card, and ask them to provide it over the phone.
Some banks also print the transit number on your debit card or in your welcome package when you open the account. If you are unsure which number is which, your bank can clarify — they handle this question regularly.
How transit numbers work in transfers and direct deposits
When you set up a direct deposit (such as for payroll or government payments), your employer or the paying organization needs your transit number, institution number, and account number. These three pieces of information create a complete address that tells the banking system exactly where to deposit the money.
When you send money to someone else using online banking or a wire transfer, you provide their transit number, their institution number, and their account number. The sending bank uses this information to route the funds to the correct receiving branch. Without the correct transit number, the transfer may be delayed or sent to the wrong branch, which can cause the money to be returned or held in limbo.
The transit number is also used for automatic bill payments and recurring transfers. If you set up a payment to go to the same account repeatedly, the system uses the transit number to ensure each payment reaches the right destination.
Transit number versus institution number
These two numbers work together but serve different purposes. Your transit number identifies the specific branch of your bank. Your institution number identifies the bank itself. For example, if you bank at Royal Bank of Canada (RBC), the institution number is 003. If your account is at the RBC branch in downtown Toronto, that branch has its own transit number.
When you provide banking information to someone, you need to give them both numbers along with your account number. Some forms ask for all three separately; others ask for a "branch transit number" (which is the transit number) and an "institution number" as two distinct fields. If you are unsure which number goes where, ask the person or organization requesting the information — they can tell you which fields correspond to which numbers.
What happens if you provide the wrong transit number
If you give someone an incorrect transit number, the transfer may still go through, but it could be routed to the wrong branch. The receiving bank's system may catch the error and return the money to the sender, or it may process the transfer to a different branch within the same bank. In some cases, the money ends up in a suspense account while the banks sort out where it should go.
If money is sent to your account with the wrong transit number, contact your bank immediately. Provide them with the details of the transfer — the amount, the date it was supposed to arrive, and the sender's information. Your bank can trace the transaction and either retrieve the funds or work with the sending bank to correct the routing.
For this reason, it is worth double-checking the transit number before you provide it to someone, especially for large transfers or recurring payments. A simple mistake in one digit can cause unnecessary delays.
Transit numbers for different types of accounts
Your transit number depends on which branch your account is registered with, not on the type of account you hold. Whether you have a chequing account, savings account, or money market account, the transit number remains the same. If you have multiple accounts at the same branch, they all share the same transit number but have different account numbers.
If you move your account to a different branch or switch banks entirely, your transit number will change. When this happens, you need to update your direct deposit information with your employer or any organization that sends you regular payments. You should also update any automatic bill payments or recurring transfers you have set up.
Frequently Asked Questions
Is my transit number the same as my account number?
No. Your transit number identifies your branch; your account number identifies your specific account within that branch. On a cheque, the transit number appears first (four or five digits), followed by your account number (eight digits). You need both to complete a transfer.
Can I use my transit number to receive money from outside Canada?
International transfers typically require different information, such as your SWIFT code or IBAN, depending on the country sending the money. Ask your bank for the correct routing information for international deposits. Providing only a transit number may not be sufficient for money coming from outside Canada.
What if my bank doesn't have branch numbers?
Some online-only banks or credit unions may not use traditional branch transit numbers. In these cases, they provide alternative routing information for transfers. Contact your bank directly to ask what information you should provide when someone needs to send you money.
Do I need to memorize my transit number?
No. You can look it up on a cheque, in your online banking account, or by calling your bank whenever you need it. Most people do not memorize it because they only need it occasionally, and it is always available in multiple places.
What if I provide my transit number to the wrong person?
A transit number alone cannot be used to withdraw money from your account or cause fraud. You would also need your account number and other security information. However, you should still be cautious about sharing banking details with people you do not trust, as they could use the information to attempt unauthorized transactions.
