Your routing number is a nine-digit code that identifies your specific bank or credit union
The routing number is printed on the bottom left of every check you receive from your bank. It tells other banks and payment systems which financial institution holds your account. When you send money to someone else's account — whether through a wire transfer, automatic bill payment, or direct deposit — that routing number is how the money finds the right bank.
Think of it like a postal code for your bank. Your account number is like your street address. Together, they tell the sending bank exactly where to deliver the money.
Every bank and credit union has its own routing number, and some large banks have more than one depending on which state or region the account is in. The number never changes for your account, and you don't need to do anything to "get" it — it's already assigned to you when you open the account.
Key Takeaways
- Your routing number appears as a nine-digit code on the bottom left of your checks, before your account number.
- The routing number identifies your bank or credit union, while your account number identifies your specific account within that bank.
- You need both numbers together when setting up direct deposit, wire transfers, or automatic bill payments.
- Your bank's website, customer service phone line, or mobile app can provide your routing number if you don't have a check available.
- Large banks may have different routing numbers for different states or regions, so confirm you have the correct one for your location.
How to read the routing number on a check
Open a check from your checking account and look at the bottom of the page. You will see a series of numbers printed in a special magnetic ink. The first nine digits on the far left are your routing number. After those nine digits comes your account number, which is longer and unique to your account.
The routing number always comes first and is always exactly nine digits. If you see fewer or more digits in that first group, you are looking at a different number. Some checks also print the routing number in the top right corner for reference, but the official version is always at the bottom left.
Finding your routing number without a check
If you don't have a check in front of you, your bank can give you the routing number in seconds. Call the customer service number on the back of your debit card, log into your online banking account, or visit your bank's website and search for "routing number." Most banks list it in the account information or FAQ section.
Your bank's mobile app often displays it too. Open the app, go to account details or settings, and look for routing number or bank information. Some banks show it right on the account summary screen.
If you are at a branch in person, any teller can write it down for you. This is useful if you need to confirm you have the correct routing number for your specific location, since large banks sometimes have different numbers for different regions.
When you need to provide your routing number
You will need your routing number and account number together whenever you set up a payment that moves money into or out of your checking account. Common situations include setting up direct deposit for your paycheck, arranging automatic bill payments to utilities or loan servicers, or sending a wire transfer to another person's account.
Some employers ask for both numbers before your first paycheck so they can deposit your wages directly. Landlords or mortgage servicers may ask for them to set up automatic rent or payment withdrawals. If you are sending money to someone else's account at a different bank, you will need their routing number and account number, not yours.
Routing number versus account number
These two numbers work together but mean different things. Your routing number identifies the bank itself — it is the same for everyone who banks at that institution in that region. Your account number is unique to you and identifies which specific account within that bank is yours.
Imagine a large apartment building. The routing number is the building's address. Your account number is your apartment number inside that building. The mail carrier needs both to deliver a package to the right place. A payment system needs both to move money to the right account at the right bank.
What to do if you have multiple accounts at the same bank
Each account you hold — whether it is a checking account, savings account, or money market account — has its own account number. They all share the same routing number because they are all at the same bank in the same region.
When you set up a payment or transfer, make sure you are providing the account number for the specific account you want the money to go to or come from. Using the correct routing number but the wrong account number will send the money to the wrong place within your bank.
Routing numbers for different states and branches
Large national banks sometimes have different routing numbers depending on which state the account was opened in or where the branch is located. If you opened your account in one state and moved to another, your original routing number usually still works, but it is worth confirming with your bank.
When you set up a payment, use the routing number that matches your account's home location, not your current location. If you are unsure which one is correct, call your bank or check your account information online — they will show you the routing number associated with your specific account.
Frequently Asked Questions
Is my routing number the same as my bank's code or SWIFT code?
No. Your routing number is used for domestic transfers within the United States. A SWIFT code is used for international wire transfers and is different. If you are sending money to someone outside the U.S., ask your bank for the SWIFT code instead of the routing number.
Can someone steal money from my account if they have my routing number?
They would need both your routing number and your account number, and even then, most banks require additional verification before processing a transfer. Do not share either number with people you don't trust, but a routing number alone is not enough to access your account.
What if I give someone the wrong routing number?
The payment may be rejected, delayed, or sent to the wrong bank. If this happens, contact the person or organization that sent the payment and ask them to reverse it, then provide the correct routing number. Direct deposits are usually caught and corrected quickly by the employer's payroll system.
Do I need a routing number to use my debit card?
No. You only need a routing number when setting up transfers between bank accounts or direct deposits. Swiping or inserting your debit card at a store or ATM does not require it.
Where do I find the routing number if my checks are blank or custom-printed?
Blank checks and custom-printed checks still have the routing number printed at the bottom left in magnetic ink. If for some reason it is not there, call your bank or log into your account online to find it.
