Your routing number is printed on the bottom left of every check you receive from your bank
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. The format looks like this: the routing number comes first, then your account number, then the check number on the far right. All three are printed in magnetic ink that machines can read.
If you do not have checks in front of you, your routing number is also available through your bank's website, your mobile app, or by calling the customer service number on the back of your debit card. Many banks print it on statements as well, though the location varies by institution.
Key Takeaways
- Your routing number appears in the bottom left corner of every check, printed in magnetic ink before your account number.
- You can find your routing number on your bank's website, in your mobile app, or by calling customer service without needing a check.
- The nine-digit routing number identifies your bank; your account number identifies your specific account within that bank.
- If you cannot locate your routing number, your bank's website usually has a search tool where you enter your state and bank name.
Reading the numbers at the bottom of a check
The bottom of a check contains three separate numbers in a specific order. On the far left is the routing number—always nine digits. In the middle is your account number, which varies in length depending on your bank but is typically ten to twelve digits. On the far right is the check number, which is usually four digits and identifies that individual check.
These numbers are printed in MICR font (Magnetic Ink Character Recognition), which looks slightly different from regular text. This special ink allows bank machines to read and process checks automatically. The numbers are always in the same order on every check from your account, so once you find your routing number on one check, it will be the same on all your other checks.
Finding your routing number without a check
If you do not have checks available, log into your bank's website or open the mobile app. Most banks display your routing number in the account details or settings section. Look for a tab labeled "Account Information," "Account Details," or "Routing and Account Numbers." Some banks require you to click through to a specific account if you hold multiple accounts with them.
If you cannot find it online, call the customer service number on the back of your debit card or the number listed on your bank statement. A representative can provide your routing number immediately. You can also visit a branch in person with your ID, and a teller will give you the number on the spot.
Using an online routing number lookup tool
Most banks maintain a routing number search tool on their website. You typically enter your state and the name of your bank or branch, and the tool returns the correct routing number. This is useful if you have moved, changed branches, or are unsure whether your bank has merged with another institution.
Be careful to use only your bank's official website or the Federal Reserve's routing number database. Do not enter your account number or personal information into third-party lookup sites. Your routing number is public information—it is printed on every check you write—but you should never share your full account number with unknown websites.
Why banks have multiple routing numbers
Large banks and credit unions sometimes maintain separate routing numbers for different regions, branches, or processing centers. If you have moved to a different state or switched to a different branch of the same bank, your routing number may have changed. This is why it is important to verify your current routing number rather than relying on an old check.
When you set up direct deposit or automatic payments, always use the routing number associated with the specific branch where your account is held. Using an outdated routing number can cause deposits to be delayed or sent to the wrong account. If you are uncertain, contact your bank directly to confirm the correct routing number for your account.
What happens if you use the wrong routing number
If you provide an incorrect routing number for a direct deposit or wire transfer, the transaction may be rejected outright, or it may be sent to a different bank or account. Some payments take several days to process, so the error might not be caught immediately. When the receiving bank realizes the routing number does not match their institution, they typically return the funds to the sender.
The return process can take five to ten business days, which means your money is delayed but not lost. To avoid this, double-check your routing number before submitting any direct deposit forms or payment instructions. If you have already sent money with the wrong routing number, contact your bank's customer service immediately to report the error and ask about recovery options.
Routing numbers versus account numbers
These two numbers serve different purposes and should never be confused. Your routing number identifies your bank or credit union—it is the same for all customers at that institution (or at that branch, depending on the bank's structure). Your account number identifies your specific checking account within that bank. Together, they form a complete address for your money.
When you set up direct deposit, you need both numbers. When you write a check, both numbers are printed on it. If someone asks for your "routing number," they are asking only for the nine-digit code on the left; they should already have or separately request your account number. Sharing your routing number alone does not put your account at risk, since it is printed on every check you write.
Frequently Asked Questions
Is my routing number the same for all my accounts at the same bank?
Usually yes, but not always. If your bank has multiple routing numbers by region or branch, different accounts might have different routing numbers. Check your statements or contact your bank to confirm. When setting up direct deposit, use the routing number from the account where you want the money to go.
Can I find my routing number on my debit card?
No, your debit card does not display your routing number. However, the customer service number on the back of your card will connect you to someone who can provide it. Your routing number is printed on checks and available through your bank's website or app.
What if my bank merged with another bank?
After a merger, your routing number may change. Contact your bank or check your most recent statement to confirm your current routing number. If you have automatic payments or direct deposits set up, you may need to update them with the new routing number to avoid delays.
Is it safe to share my routing number?
Yes. Your routing number is public information printed on every check you write. Sharing it alone does not allow anyone to access your account. However, never share your full account number with unknown sources, and never provide both your routing number and account number to untrusted websites.
Why do I need a routing number for direct deposit?
Your employer or the organization sending the payment needs to know which bank to send your money to. The routing number tells their system where your bank is located and how to process the transfer. Without it, the payment cannot reach your account.
