Your routing number is printed on the bottom left of every check you write
The routing number is a nine-digit code that identifies your specific bank or credit union. On a paper check, it appears in the bottom left corner, before your account number. If you write checks regularly, you already have this number in front of you every time you look at one.
The routing number stays the same for your bank, no matter which account you hold there. If you have multiple checking accounts at the same bank, they all share the same routing number — only the account number changes between them.
You need the routing number when you set up direct deposit, arrange wire transfers, or authorize automatic bill payments. It tells the financial system which bank to send money to or pull money from.
Key Takeaways
- Your routing number appears in the bottom left corner of any check you have, printed as a nine-digit code before your account number.
- You can find your routing number on your bank's website, by calling customer service, or through your online banking portal without needing a check.
- The routing number is specific to your bank or credit union, not to your individual account — all your accounts at that bank share the same routing number.
- Banks and credit unions maintain public routing number databases, so you can search by institution name if you need to verify the number.
Finding your routing number without a check
If you do not have checks handy, your bank's website has your routing number listed in the customer service or FAQ section. Most banks publish this information publicly because it is not sensitive — the routing number alone cannot access your account.
Log into your online banking portal and look for account details or account information. Many banks display the routing number alongside your account number in that section. If you cannot find it there, call your bank's customer service line — they can read it to you in under a minute.
Credit unions work the same way. Your routing number is available through your credit union's website, mobile app, or by phone. Some credit unions call it a "transit number" instead, but it serves the same purpose.
The difference between routing number and account number
The routing number identifies your bank. The account number identifies your specific account within that bank. On a check, they appear together at the bottom: the routing number comes first (nine digits), then the account number (usually ten to twelve digits), then the check number.
When you set up direct deposit, you need both numbers. Your employer uses the routing number to find your bank and the account number to deposit money into the right account. If you give only one, the transaction will not go through.
For wire transfers and bill payments, the same rule applies — the system needs both pieces of information to route your money correctly.
Verifying your routing number is correct
If you are unsure whether you have the right number, the Federal Reserve maintains a public database of routing numbers. You can search by bank name and state to confirm the nine-digit code matches what your bank gave you.
Your bank's official website is the most reliable source. Scammers sometimes post fake routing numbers online, so always pull the number from your bank's actual website, your checks, or a direct call to customer service — not from a third-party site.
If a company asks you to verify your routing number before you give it to them, that is normal. Employers, payroll processors, and bill payment services all ask you to confirm the number to prevent mistakes.
What happens if you use the wrong routing number
If you provide an incorrect routing number, the transaction usually fails and bounces back. Direct deposit will not land in your account. A bill payment will not go through. The money does not disappear — it either returns to the sender or sits in a holding account while the bank tries to sort out where it should go.
If money does land in the wrong account by mistake, contact your bank immediately. They can trace the transaction and work with the other bank to recover the funds, but the process takes time. Catching the error quickly makes recovery easier.
This is why double-checking the routing number before you submit it matters. A few seconds of verification prevents weeks of back-and-forth if something goes wrong.
Routing numbers for different types of transfers
The routing number you use for direct deposit is the same one you use for bill payments, wire transfers, and ACH transfers. One routing number covers all of these. You do not need different numbers for different transaction types.
Some banks maintain separate routing numbers for wire transfers versus ACH transfers, though this is less common. If your bank is one of them, they will tell you which number to use for which type of transfer. When in doubt, ask your bank which routing number applies to the specific transaction you are making.
International wire transfers sometimes require additional information beyond the routing number — such as a SWIFT code — but for domestic transfers within the United States, the routing number is what you need.
Frequently Asked Questions
Is my routing number the same as my bank's main routing number?
Usually yes, but some large banks operate multiple routing numbers for different regions or branches. Your personal routing number is printed on your checks and shown in your online banking portal. That is the one to use for your transactions. If you are unsure, use the number from your check or your bank's website rather than a general number you find elsewhere.
Can someone access my account with just my routing number?
No. The routing number identifies your bank, not your account. Someone would need both your routing number and your account number to move money. Even then, most transactions require additional verification. The routing number alone is not sensitive information — it is printed on every check you write.
Do I need a different routing number for each account I have?
No. All accounts you hold at the same bank share the same routing number. Only your account number changes between accounts. When you set up direct deposit or bill payments for a different account, you use the same routing number but provide the different account number.
What if my bank merged with another bank?
Your routing number may change after a merger, but your bank will notify you and provide the new number. Old checks with the old routing number may still work for a period of time, but you should update any automatic payments or direct deposit arrangements with the new routing number to avoid delays.
Where do I find my routing number if I bank online only?
Log into your online banking account and look for account details or account information — the routing number is usually displayed there. You can also call your bank's customer service line or visit their website. Online-only banks publish their routing numbers just like traditional banks do.
