What a routing number is and why you need it
A routing number is a nine-digit code that identifies the specific bank or credit union where your account lives. When money moves between banks — whether you're setting up direct deposit, sending a wire transfer, or paying a bill through your bank's website — the routing number tells the sending bank exactly where to send it. Without the correct routing number, the transfer can go to the wrong institution or bounce back.
You'll need your routing number whenever you give someone else instructions to deposit money into your account. This includes tax refunds, stimulus payments, insurance payouts, and business reimbursements. The IRS, state tax agencies, and other government bodies use routing numbers to deposit refunds directly into your bank account instead of mailing a check.
Key Takeaways
- Your routing number is a nine-digit code specific to your bank or credit union branch, and it is different from your account number.
- You can find your routing number on the bottom left of your checks, on your bank's website, or by calling your bank's customer service line.
- The routing number for direct deposit may differ from the one for wire transfers at the same bank, so confirm which one you need before submitting it.
- If you provide an incorrect routing number for a tax refund or government payment, the deposit will fail and you may receive a check by mail instead, delaying your money by weeks.
Finding your routing number on a check
The easiest place to find your routing number is on a blank check from your account. Look at the bottom left corner of the check. You will see three groups of numbers separated by vertical lines. The first group — always nine digits — is your routing number. The second group is your account number, and the third is the check number itself.
This method works only if you have checks from your current account at your current bank. If you've switched banks or closed an account, old checks will have the wrong routing number. If you don't have checks or prefer not to use them, move to the next method.
Looking it up on your bank's website
Log into your online banking account and look for a section labeled "Account Information," "Routing Number," or "Bank Details." Most banks display this information on the account summary page or in a dedicated settings area. Some banks require you to click through to a specific account to see its routing number, since different accounts at the same bank can sometimes use different routing numbers.
If you cannot find it online, check your bank's FAQ or help section — many banks have a dedicated page for routing numbers. You can also search "[Your Bank Name] routing number" in a search engine; most banks publish this information publicly on their website.
Calling your bank to confirm the number
If you're unsure whether you have the right routing number, or if you're about to submit it for a large payment like a tax refund, call your bank's customer service line. The number is usually on the back of your debit card or on your bank's website. Have your account number ready when you call.
Tell the representative you need the routing number for direct deposit or the specific purpose you have in mind. Some banks use different routing numbers for wire transfers versus ACH transfers (the method used for most direct deposits and bill payments), so naming your purpose helps the representative give you the correct one.
Understanding routing number variations
A single bank may have multiple routing numbers depending on the type of transfer. The routing number for direct deposit (an ACH transfer) is often different from the routing number for a wire transfer. If you're setting up direct deposit for a tax refund or paycheck, you need the ACH routing number, not the wire routing number. Submitting the wrong one will cause the deposit to fail.
Credit unions also have routing numbers, and they work the same way as bank routing numbers. If your account is at a credit union, the process for finding the number is identical — check your checks, log into online banking, or call the credit union's main line.
What happens if you submit the wrong routing number
If you provide an incorrect routing number when setting up direct deposit for a tax refund or government payment, the transfer will be rejected. The sending bank will attempt to return the money to the originating account, which can take one to three weeks. Once the money is returned, the IRS or other agency may reissue the payment by check instead, adding another one to two weeks to your wait time.
For this reason, double-check your routing number before submitting it for any refund or payment. If you're unsure, call your bank and have them confirm it while you're on the phone, then write it down before you enter it into the form.
Routing numbers for online banks and smaller institutions
Online banks and smaller regional institutions publish their routing numbers on their websites just as traditional banks do. Log into your account, check the FAQ section, or search the bank's name plus "routing number." If the information is not immediately visible, call the bank's customer service line — they can provide it in seconds.
Some online banks partner with larger institutions for processing, which means your routing number may belong to a different bank than the one you opened your account with. This is normal and does not affect how the routing number works. Use the routing number your bank provides, not the name on the check or website.
Frequently Asked Questions
Is my routing number the same as my account number?
No. Your routing number identifies your bank; your account number identifies your specific account within that bank. Both are needed for direct deposit. The routing number is always nine digits and appears on the left side of the bottom of a check. Your account number is longer and appears in the middle.
Can I use the same routing number for wire transfers and direct deposit?
Not always. Many banks use different routing numbers for ACH transfers (direct deposit) and wire transfers. Before you submit a routing number, confirm with your bank which type of transfer you're making and ask for the correct routing number for that method.
What if my bank doesn't have a routing number listed online?
Call your bank's customer service line. Every bank and credit union has a routing number; some simply don't publish it prominently on their website. A representative can provide it immediately and confirm it's the correct one for your purpose.
Do I need a different routing number if I switch banks?
Yes. Each bank has its own routing number. If you move your account to a new bank, you'll need to update the routing number with anyone who deposits money into your account — your employer, the IRS, or any other source of regular deposits.
What should I do if a direct deposit fails because of a wrong routing number?
Contact the organization that sent the payment (the IRS, your employer, or the government agency) and ask them to resubmit it with the correct routing number. Provide your bank's routing number and your account number. The resubmitted payment may take one to three weeks to arrive.
