A transit number identifies which branch of your bank holds your checking account
A transit number is a five-digit code that tells the banking system which specific branch of your bank processes your account. It is not the same as your account number, and it is not the same as your bank's main routing number. The transit number is used internally by your bank to sort checks and direct deposits to the right location.
You will see it printed on the bottom left of your checks, usually before your account number. If you have a checking account with a large national bank that has hundreds of branches, your transit number points to the exact branch where your account is held. A smaller regional bank might have fewer transit numbers, or only one.
The transit number matters most when you are depositing a check or setting up a direct deposit. It ensures the money lands in your account, not someone else's at a different branch. Without it, a deposit can be delayed or sent to the wrong place.
Key Takeaways
- Your transit number is a five-digit code printed on the bottom left of your checks that identifies your specific bank branch.
- It is different from your routing number (which is nine digits) and your account number (which is unique to you).
- You need your transit number when setting up direct deposits, wire transfers, or other transactions that route money to your account.
- If you cannot find your transit number on a check, your bank can provide it by phone or through your online banking portal.
Where to find your transit number
The easiest place to find your transit number is on a check from your checking account. Look at the bottom left corner. You will see a series of numbers printed in a special magnetic ink format. The first five digits are your transit number. The remaining digits are your account number.
If you do not have checks or cannot read the number clearly, log into your online banking account. Most banks display your transit number in the account details or settings section. You can also call your bank's customer service line and ask them to read it to you over the phone. Have your account number and a form of identification ready.
Some banks print the transit number on your debit card or in your account statements, though this is less common. If your bank does not list it anywhere obvious, ask a teller at your branch in person. They can write it down for you when ready.
Transit number versus routing number: what is the difference
The routing number is a nine-digit code that identifies your entire bank across the country. It is the same for all customers of that bank, no matter which branch they use. The routing number is used for wire transfers, ACH transfers (like direct deposits), and other transactions that move money between different banks.
The transit number is five digits and identifies your specific branch within that bank. It is used for internal bank operations and check processing. Two customers at the same bank but different branches will have different transit numbers but the same routing number.
In practice, you will use your routing number far more often than your transit number. When you set up direct deposit at work or receive a wire transfer, you give your routing number. Your transit number is mainly relevant for check deposits and some internal bank transfers. If you are unsure which one you need, ask the person or organization requesting the information—they will tell you.
When you actually need your transit number
You need your transit number when depositing a check at an ATM or through mobile deposit. The banking system uses it to route the check to the correct branch for processing. Without it, the deposit may be delayed or rejected.
You may also need it if you are setting up a transfer between two accounts at the same bank but different branches. Some banks ask for the transit number to may support the money goes to the right location. Wire transfers between different banks, by contrast, use your routing number instead.
If you are mailing a check to someone and they ask where to deposit it, you do not need to give them your transit number. They only need the account number and routing number printed on the check itself. The transit number is for your bank's internal use.
What happens if you use the wrong transit number
If you provide an incorrect transit number, the deposit or transfer may be delayed while the bank tries to figure out where the money should go. Some transactions will be rejected outright, and you will have to resubmit with the correct number. This can take a few business days to resolve.
In rare cases, a deposit sent to the wrong transit number might end up in a different account at a different branch. The bank's error-correction process will catch this eventually, but it can take a week or more to sort out. This is why it is worth taking 30 seconds to verify the number before you submit a transaction.
If you have already submitted a transaction with the wrong transit number and it has not been processed yet, contact your bank when ready. They may be able to stop it and resubmit it with the correct information. Once the transaction has cleared, reversing it is much harder.
Transit numbers for online and mobile banking
If you bank entirely online and never use checks, you may never need your transit number. Online transfers between accounts at the same bank usually do not require it—you just select the accounts from a dropdown menu. The bank handles the routing automatically.
Mobile deposit (taking a photo of a check with your phone) does require your transit number to be on the check itself, but you do not have to enter it manually. The app reads the magnetic ink numbers at the bottom of the check and processes them automatically.
The only time an online or mobile banking customer typically needs to know their transit number is if they are troubleshooting a problem or if they are setting up a transfer to another bank. In that case, they would use their routing number instead.
Frequently Asked Questions
Is my transit number the same as my account number?
No. Your account number is unique to you and identifies your specific account. Your transit number identifies your branch. Both are printed on your checks, but they are separate numbers. The transit number comes first (five digits), followed by your account number.
Can I use my transit number for direct deposit at work?
No. Your employer needs your routing number (nine digits) and your account number for direct deposit, not your transit number. If you give them your transit number by mistake, the deposit will likely be rejected. Check your offer letter or payroll system to see which number they are asking for.
What if my bank closed the branch where my account is held?
Your account will be transferred to another branch, and your transit number may change. Your bank will notify you of the change and send you new checks with the updated transit number. If you have pending transactions using the old transit number, contact your bank to update them.
Do I need my transit number to open a new checking account?
No. You only need your transit number once you already have an account and are using it for deposits or transfers. When you open a new account, the bank assigns you a new transit number and account number.
Can someone access my account if they know my transit number?
Your transit number alone is not enough to access your account. Someone would also need your account number and typically your PIN or online banking password. Your transit number is printed on every check you write, so it is not considered confidential information.
