Your routing number is a nine-digit code that tells the banking system which bank holds your account
The routing number is printed on the bottom left of your checks. It identifies your specific bank branch or the bank itself, depending on the institution. When you set up direct deposit, pay a bill online, or send money to someone else's account, that routing number tells the payment system exactly where to send the money.
Every bank in the United States has at least one routing number, and some large banks have multiple ones for different regions or account types. The number never changes for your account — it stays the same as long as you bank there, even if you move to a different state or switch to a different branch of the same bank.
You need this number whenever you receive money electronically (like a paycheck or tax refund) or send it out (like paying a bill or transferring funds). Without it, the transaction either fails or goes to the wrong place.
Key Takeaways
- Your routing number is a nine-digit code printed on the bottom left of your checks, before your account number.
- The routing number identifies your bank or bank branch to the payment system and never changes for your account.
- You need your routing number to set up direct deposit, pay bills online, or transfer money between accounts.
- If you cannot find your checks, you can get your routing number from your bank's website, by calling customer service, or by logging into your online banking portal.
Where to find your routing number on a check
Look at the bottom of any check you have. On the left side, you will see a series of numbers. The first nine digits are your routing number. After that comes your account number, which is longer and unique to you alone.
The routing number always appears in the same position on every check from your bank. If you have multiple checking accounts at the same bank, they will share the same routing number but have different account numbers.
How to find your routing number without a check
If you do not have checks in front of you, your bank's website usually has a page dedicated to routing numbers. Log in to your online banking account, look for a section called "Account Information," "Routing Number," or "Wire Transfer Information," and you will find it there.
You can also call your bank's customer service number (usually on the back of your debit card) and ask for your routing number. Have your account number ready, and they will give it to you in seconds. Some banks also display it in the mobile app under account details.
The Federal Reserve maintains a public database of routing numbers at frbservices.org. You can search by bank name and state to confirm your routing number if you want to double-check.
Routing number versus account number
These two numbers work together but mean different things. Your routing number identifies your bank. Your account number identifies you within that bank. Think of it like a postal address: the routing number is the city and state, and the account number is your specific street address.
Both numbers appear on your checks in the same order: routing number first (nine digits), then account number (usually ten to twelve digits). You need both to complete most transactions. If you give someone only the routing number without the account number, they cannot deposit money into your account.
When you need to provide your routing number
Direct deposit is the most common reason. Your employer or the government (for tax refunds or benefits) needs both your routing number and account number to deposit money into your account. Without the correct routing number, the deposit goes nowhere or bounces back.
Online bill pay also requires it. When you set up automatic payments through your bank's website or app, you enter your routing and account numbers so the bank knows where to pull the money from. Wire transfers, ACH transfers between banks, and setting up automatic transfers all require the same information.
Some employers and government agencies ask for it when you enroll in direct deposit. Mortgage lenders, investment firms, and insurance companies sometimes ask for it too, so they can withdraw payments directly from your account.
What happens if you give the wrong routing number
If you provide an incorrect routing number, the payment system sends the money to the wrong bank. It does not go into your account. The transaction may fail when ready, or it may take days or weeks to bounce back to the sender.
If someone deposits money using your wrong routing number, that money goes into someone else's account at a different bank. You will not see it. The sender will eventually get it back, but the process can take one to three weeks.
For this reason, always double-check the routing number before you give it out. Copy it directly from your check or your bank's official website rather than relying on memory.
Routing numbers for different types of accounts
Most checking and savings accounts at the same bank share the same routing number. A few large banks use different routing numbers for different regions or account types, but this is uncommon. If you have both a checking and savings account at the same bank, you can usually use the same routing number for both.
Credit unions have their own routing numbers, separate from banks. If you have an account at a credit union, ask the credit union for its routing number — it will not be the same as a bank's.
Online banks have routing numbers just like brick-and-mortar banks. You can find yours on the bank's website or by calling customer service. The process is identical.
Frequently Asked Questions
Is my routing number the same as my bank's routing number?
Usually yes, but not always. Most people at the same bank share one routing number. However, some large banks assign different routing numbers to different regions or branches. Check your check or your bank's website to confirm which one is yours.
Can someone steal money from my account if they have my routing number?
Not with just the routing number alone. They also need your account number. Together, these two pieces of information allow someone to set up unauthorized transfers or payments from your account. If you suspect fraud, contact your bank when ready.
Do I need my routing number to receive a wire transfer?
Yes. The person sending the wire needs both your routing number and your account number. Some banks also ask for a SWIFT code if the wire is coming from outside the United States. Ask your bank what information the sender needs.
What if my bank merged with another bank — does my routing number change?
Not automatically. Your routing number stays the same unless your bank explicitly tells you it has changed. If a merger happens, the bank will notify you and update any direct deposits or automatic payments on your behalf. Check your statements or call to confirm.
Can I use the same routing number for multiple accounts at the same bank?
Yes. All your accounts at the same bank typically share the same routing number. The account number is what distinguishes one account from another. When you provide both numbers together, the bank knows exactly which account to use.
