Your routing number is a nine-digit code that tells banks where your checking account lives
A routing number is a nine-digit identifier assigned to your bank or credit union by the Federal Reserve. It tells the financial system which institution holds your account. When money moves between banks—whether you're setting up direct deposit, paying a bill online, or sending a wire transfer—the routing number is how the sending bank knows where to send it.
Every bank and credit union has its own routing number, sometimes more than one if the institution operates multiple processing centers. The number itself is not secret; it appears on your checks, and you can find it on your bank's website or by calling customer service. You need it to receive money from employers, government agencies, insurance companies, and other payers.
Key Takeaways
- Your routing number is a nine-digit code printed on the bottom left of your checks and identifies which bank or credit union holds your account.
- The routing number is different from your account number; together they tell a payer exactly where to send your money.
- You can find your routing number on your bank's website, by calling customer service, or by looking at a check or bank statement.
- Routing numbers are public information and safe to share when you need to receive direct deposits, tax refunds, or other payments.
Where to find your routing number
The easiest place to look is a check from your account. On the bottom left of any check, you'll see three groups of numbers separated by vertical lines. The first group of nine digits is your routing number. The second group is your account number, and the third is the check number itself.
If you don't have a check handy, log into your bank's website or mobile app. Most banks display the routing number in the account details or settings section. You can also call your bank's customer service line—the number is usually on the back of your debit card—and ask for your routing number. Credit unions work the same way; call or log in to find yours.
Your bank statement, whether paper or electronic, may also list the routing number. Some banks print it at the top or bottom of the statement; others include it in the account information section.
Routing number versus account number
These two numbers work together but do different jobs. Your routing number identifies your bank or credit union—it's the same for all customers at that institution. Your account number identifies your specific checking account within that bank. Think of the routing number as the bank's address and the account number as your mailbox number inside that building.
When you set up direct deposit for a paycheck or tax refund, you need both numbers. The routing number tells the payer's bank which institution to send the money to; the account number tells your bank which account to deposit it into. If you give only one, the payment will not go through.
When you need to provide your routing number
You'll need your routing number whenever you want money deposited directly into your checking account. Common situations include setting up direct deposit with your employer, receiving a tax refund from the IRS, getting a state tax refund, receiving unemployment benefits, or setting up automatic bill payments from your account.
Insurance companies, government agencies, and businesses that owe you money will ask for both your routing number and account number before they can send a payment. Some will ask you to provide this information on a form; others will ask over the phone or through an online portal.
Is it safe to share your routing number
Yes. Your routing number is public information and safe to share. It appears on every check you write, and anyone who receives a check from you already has it. Banks publish routing numbers on their websites and in public directories.
However, never share your routing number along with your account number to someone you don't trust or who contacts you unexpectedly. Scammers sometimes call or email claiming to be from your bank and ask for account information. Your bank will never ask for your account number or routing number unsolicited. If someone calls asking for these details, hang up and call your bank directly using the number on your debit card or statement.
What happens if you use the wrong routing number
If you provide an incorrect routing number, the payment will go to the wrong bank. The sending institution will eventually catch the error and return the money to the payer, but this can take several days or weeks. During that time, you won't have the money you expected, and the payer may think the payment failed.
If you're waiting for a direct deposit and suspect you gave the wrong routing number, contact your employer or the payer immediately and provide the correct information. They can often resubmit the payment. For tax refunds, you can check the status through the IRS website or your state's tax authority to see if there was an error.
Routing numbers for different types of accounts
Your checking account routing number is specific to that account type at your bank. If you also have a savings account at the same bank, it uses the same routing number. However, if you bank at multiple institutions, each one has its own routing number.
Some large banks operate multiple processing centers and may have different routing numbers depending on where your account was opened or which branch you use. If you're unsure which routing number to use, ask your bank directly or check the account details section of your online banking portal, which usually shows the correct routing number for your specific account.
Frequently Asked Questions
Can I use the same routing number for all my accounts at one bank?
Yes. All checking and savings accounts at the same bank typically share the same routing number. The routing number identifies the bank; your account number identifies which specific account within that bank receives the money.
What if my bank merged with another bank?
After a merger, your routing number may change. Your bank will notify you and update your account information. If you have direct deposits set up, contact your employer to provide the new routing number. For tax refunds already submitted with the old routing number, check the status through the IRS or your state tax authority.
Do I need a routing number to use my debit card?
No. You only need your routing number when money is being deposited into your account or when you're paying from your account using banking information rather than the card itself. Debit card purchases don't require a routing number.
Is my routing number the same as my bank's SWIFT code?
No. A SWIFT code is used for international wire transfers and is different from a routing number. Routing numbers are used only for transfers within the United States. If you're sending money internationally, ask your bank for the SWIFT code instead.
What if I can't find my routing number anywhere?
Call your bank or credit union directly. Customer service can provide your routing number over the phone in seconds. Have your account number or debit card ready when you call.
