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

When you write a check or set up a direct deposit, you need three pieces of information to route money to the right place: your bank's main routing number, your account number, and your transit number. The transit number tells the payment system which specific branch of your bank to send the money to. Think of it like a street address — the routing number is the city, and the transit number is the exact building.

In Canada, transit numbers are five digits long. In the United States, the system works slightly differently — American banks use a nine-digit routing number that includes branch information built in, so you typically do not need a separate transit number. If you bank in Canada or receive payments from Canada, you will encounter transit numbers. If you bank only in the US, you will use routing numbers instead.

You can find your transit number on the bottom left of your checks, right before your account number. If you do not have checks, your bank can tell you the number in seconds — call the branch where you opened your account, or log into online banking and look for account details.

Key Takeaways

  • A transit number identifies the specific branch of your bank, while a routing number identifies the bank itself.
  • Transit numbers are used in Canada and are five digits long; the US uses routing numbers instead.
  • You need your transit number, routing number, and account number together to set up direct deposits or receive wire transfers.
  • Your transit number appears on the bottom left of your checks, before your account number.
  • If you cannot find it, your bank branch can provide it in one phone call.

How transit numbers work with routing numbers

A routing number and a transit number serve different purposes, and you need both for most electronic payments. The routing number identifies your bank — for example, Royal Bank of Canada has one routing number for the entire institution. The transit number narrows it down to the branch where your account lives.

When you set up direct deposit at work or receive a wire transfer, you provide both numbers. The payment system uses the routing number to find your bank, then uses the transit number to find the right branch within that bank. Without the transit number, the payment might be delayed or sent to the wrong location.

In the United States, this information is combined into a single nine-digit routing number, so American banks do not use the term "transit number." If you are moving between the US and Canada or working with international payments, knowing the difference prevents confusion.

Where to find your transit number

The easiest place to look is the bottom of a check you have written. On the left side, you will see a series of numbers. The first five digits are your transit number. The next eight digits are your account number. The last set of numbers is your routing number.

If you do not have checks or cannot read them clearly, log into your online banking account. Most banks display your transit number in the account details or account summary section. Some banks label it "branch number" or "branch transit number" instead of "transit number."

You can also call your bank branch directly. Have your account number ready, and they will give you the transit number over the phone. This takes less than a minute and requires no paperwork.

When you need your transit number

You need your transit number whenever you are setting up a payment that routes to a specific branch. The most common situation is direct deposit — when your employer deposits your paycheck into your account. Your employer's payroll system uses the transit number to send the money to the right branch.

You also need it for wire transfers, both incoming and outgoing. If someone is sending you money by wire, they will ask for your transit number along with your account number and routing number. If you are sending money out, your bank will ask for the recipient's transit number.

Some bill payment systems and money transfer services also ask for transit numbers, though many now accept account numbers alone. When in doubt, provide it — having the extra information never causes problems, and leaving it out sometimes does.

Transit numbers and account security

Your transit number is not secret information, and sharing it does not put your account at risk. It is printed on every check you write and is visible to anyone who sees your checks. The number only tells someone which branch your account is at — it does not let them access your money or move funds.

To actually move money from your account, someone would need your account number and your online banking password, or they would need to forge a check with your signature. The transit number alone cannot do either of those things.

That said, you should never share your full banking information (transit number, account number, and routing number together) with someone you do not trust. While the transit number itself is safe to share, the combination of all three numbers can be used to set up unauthorized payments. Only provide complete banking details to your employer, your bank, or other organizations you have chosen to work with.

Transit numbers for different types of accounts

Your transit number depends on the branch where you opened your account, not on the type of account you have. A checking account, savings account, and money market account at the same branch will all have the same transit number. If you move your account to a different branch, your transit number changes.

If you have accounts at multiple branches of the same bank, each account has its own transit number based on where that account is held. This matters if you are setting up transfers between your own accounts — you need to use the correct transit number for each one.

Some online banks that do not have physical branches use a single transit number for all customers. When you open an account with an online-only bank, ask which transit number to use, or check your account details in online banking.

What happens if you use the wrong transit number

If you provide an incorrect transit number, the payment may be delayed while the bank tries to figure out where it should go. In some cases, the payment is sent to the wrong branch and has to be rerouted, which adds a few days to the process. In rare cases, if the transit number does not exist, the payment may be rejected and sent back to the sender.

Direct deposits are usually the most forgiving — if the transit number is slightly wrong but the account number is correct, payroll systems often route the money to the right place anyway. Wire transfers are stricter. If you provide the wrong transit number for a wire, the bank may reject it or ask you to confirm the details before processing.

If you are unsure whether you have the right number, call your bank and confirm before setting up the payment. It takes one minute and prevents delays.

Frequently Asked Questions

Is a transit number the same as a routing number?

No. A routing number identifies your entire bank, while a transit number identifies the specific branch where your account is held. In Canada, you need both. In the US, routing numbers include branch information, so transit numbers are not used.

Can I use the same transit number for all my accounts?

Only if all your accounts are at the same branch. If you have accounts at different branches of the same bank, each account has its own transit number. Check your account details or ask your bank which transit number goes with which account.

What if I moved and my branch closed?

Your account was transferred to another branch, and your transit number changed. Log into online banking or call your bank to find your new transit number. Update any recurring payments (like direct deposit) with the new number.

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

No. Debit cards work with your account number and PIN. You only need a transit number for checks, direct deposits, wire transfers, and other payments that route through the banking system to a specific branch.

Can someone steal money using just my transit number?

No. Your transit number only identifies your branch — it does not give access to your account. To move money, someone would need your account number and password, or would need to forge a check with your signature.
